Cytomorphology of gastrointestinal stromal tumors and extra-gastrointestinal stromal tumors: A comprehensive morphologic study
M Vij, V Agrawal, A Kumar, R Pandey
January-March 2013, 30(1):8-12
DOI

PMID
:23661933
Background:
The term gastrointestinal stromal tumors (GIST) is used to refer to those mesenchymal neoplasms of the gastrointestinal tract (GIT) which express CD117, a c-kit proto-oncogene protein.
Aims:
To study the cytological features of GIST and extra-gastrointestinal stromal tumors (EGIST), to correlate them with histology and to determine cytological indicators of malignancy.
Materials and Methods:
Cytological smears from patients diagnosed as GIST/EGIST on histology were retrieved. From Jan 2000 to July 2010, 26 GIST (13 primary, 12 metastatic, one recurrent) and seven EGIST (5 primary, one metastatic, one recurrent) cytologic samples from 27 patients were identified.
Results:
The patients included 20 males and 7 females with a mean age of 50.6 years. Tumor sites included stomach (5), duodenum (5), ileum (2), ileocecal (1), rectum (1), liver (9), retroperitoneum (5), mesentery (1), subcutaneous nodule (1), supra-penile lump (1), ascitic (1) and pleural fluids (1). The smears were cellular with cohesive to loosely cohesive thinly spread irregularly outlined cell clusters held together by thin calibre vessels. The tumor cells were mild to moderately pleomorphic, spindle to epithelioid with variable chromatin pattern and variable cytoplasm. Cellular dyscohesion, nuclear pleomorphism, intranuclear pseudoinclusions, prominent nucleoli, mitosis and necrosis were more prominent in malignant, metastatic and recurrent tumors.
Conclusions:
GISTs show a wide spectrum of cytological features and the presence of mitosis, necrosis and nuclear pleomorphism can help in prediction of malignant behavior. Further, cytology is a very useful screening modality in patients of GIST and EGIST to detect early recurrence and metastasis at follow-up.

Cytodiagnosis of alveolar soft part sarcoma: Report of two cases with special emphasis on the first orbital lesion diagnosed by aspiration cytology
K Majumdar, RK Saran, I Tyagi, AK Jain, A Jagetia, S Sinha, A Singh
January-March 2013, 30(1):58-61

Alveolar soft part sarcoma (ASPS) is a rare neoplasm of uncertain cell of origin. Known to occur in adolescents and young adults, this tumor usually involves the muscles and deep soft tissues of the extremities and trunk. Orbital localization is rare and not yet subjected to cytological assessment, as per our literature search. We present here two cases of ASPS diagnosed by aspiration cytology, one in the orbit and the other in the lower extremity. The cells displayed abundant clear to finely vacuolated cytoplasm, often with disrupted margins and flowing of the cytoplasmic material; prominent nucleoli and scattered bare nuclei were also seen in the background. Two close cytological differential diagnoses include metastatic renal cell carcinoma and paraganglioma. Intracytoplasmic periodic acid schiff (PAS) positive, diastase-resistant, needle-shaped crystals and corresponding rhomboid crystals with regular lattice pattern on ultrastructure are the hallmarks of this neoplasm. Due to its slowly progressive clinical course and poor outcome, preoperative diagnosis of ASPS through fine-needle aspiration cytology may be essential for deciding therapy, especially in rare and difficult locations like orbit, where adjuvant radiation may not be possible.

Image-guided fine-needle aspiration of retroperitoneal masses: The role of the cytopathologist
Ghazala Mehdi, Veena Maheshwari, Sheerin Afzal, Hena A Ansari, Ibne Ahmad
January-March 2013, 30(1):36-41
DOI
:10.4103/0970-9371.107511
PMID
:23661939
Background
: Retroperitoneal tumors constitute a difficult diagnostic category as they are not easily accessible. The advent of image-guided fine-needle aspiration (FNA) has resolved this problem significantly.
Aims
: We present a short study based on guided aspiration of retroperitoneal tumors, in which we have tried to assess the role of image-guided fine-needle aspiration cytology as a tool for pre-operative diagnosis.
Materials and Methods
: The study was conducted on patients diagnosed with retroperitoneal masses. FNA was performed under image guidance with the help of ultrasonography and/or computed tomography; smears were prepared and meticulously screened according to a fixed protocol. The results were analyzed to determine sensitivity, specificity, and diagnostic efficacy of cytopathological diagnosis using image-guided FNA techniques.
Results:
We assessed 38 patients with retroperitoneal masses. In all cases, adequate cellular material was obtained. No major complications were encountered. Statistical analysis was carried out in 35 cases; sensitivity, specificity, and diagnostic accuracy were 100% in these cases.
Conclusion:
FNA under image guidance should be considered a first-line diagnostic approach for retroperitoneal and other abdominal tumors, although caution should be exercised in case selection. In areas where advanced tests are not available, the cytotechnologist and cytopathologist have a very important role to play in ensuring accurate diagnoses.

Leishman Giemsa cocktail as a new, potentially useful cytological technique comparable to Papanicolaou staining for oral cancer diagnosis
UI Belgaumi, P Shetty
January-March 2013, 30(1):18-22
DOI
:10.4103/0970-9371.107507
PMID
:23661935
Background:
Papanicolaou staining is commonly used for staining exfoliative cytology smears with Romanowsky stains being used sparingly. Leishman Giemsa (LG) cocktail, being a relatively new staining technique, has not been used in exfoliative cytology. This easy, cost-effective and one-step technique warrants further study because of its potential application in screening of oral cancer.
Aim:
To study and evaluate the diagnostic efficiency and reliability of Leishman Giemsa (LG) cocktail in comparison with Papanicolaou (Pap) and May-Grόnwald Giemsa (MGG) stains in exfoliated cells for the detection of oral squamous cell carcinoma.
Materials and Methods:
Three smears were prepared from each 100 controls (buccal mucosa) and 100 patients, clinically diagnosed with oral squamous cell carcinoma and stained with Pap, MGG and LG cocktail stains. The slides were evaluated for the staining characteristics of nucleus and cytoplasm. The diagnostic efficiency of each stain was evaluated by comparing the cytologic diagnosis of each stain with the histopathological diagnosis. Finally, the diagnostic reliability was evaluated by comparing the three stains with each other and the histologic diagnosis.
Statistical Analysis:
The data were statistically evaluated with Friedman test, Wilcoxon sign rank test and McNemar chi square test using SPSS15 software.
Results:
The results from the histologically confirmed cases of squamous cell carcinoma and the number of cases diagnosed by Pap and LG cocktail were almost identical and both were superior to MGG. The
P
value obtained for the confirmed cases of squamous cell carcinoma in comparison for Pap
vs
MGG was 0.001, MGG
vs
LG cocktail was 0.001 and LG cocktail
vs
Pap was 0.157. Hence, no statistical significant difference was observed between the diagnostic ability of Pap and LG cocktail stains.
Conclusion:
LG cocktail is an easy, cost-effective and one-step technique comparable to Pap staining; however, it warrants further study in its potential application in screening of oral cancer.

Benign breast myoepithelioma
L Khan, S Srivastava, PK Singh, M Ather
January-March 2013, 30(1):62-64

Myoepithelioma of the breast is very rare. Breast myoepithelioma can develop in women from their early 20s right up to their 80s, but it is most common in women over 50. We report a case of 20-year-old female, who presented with a well-defined breast lump of 3 × 3 cm in size. Fine needle aspiration was performed. The cytological findings revealed good cellularity comprising monomorphic loosely cohesive sheets of plasmacytoid, round to polygonal cells with round to ovoid eccentrically placed nuclei, finely dispersed chromatin, and moderate amount of cytoplasm. On the basis of cytological findings, a diagnosis of benign myoepithelioma (plasmacytoid type) was made which was confirmed on histopathologic examination. The breast is a very rare localization for this type of tumor. The benign character of the disease in conjunction with its slow progression could delay its detection and diagnosis. A detailed pathology examination is a prerequisite for avoidance of misleading diagnosis.

Adenomatoid tumor is a benign neoplasm of the male and female genital tracts arising from mesothelial cells. Fine needle aspiration cytology (FNAC) plays a pivotal role in its preoperative diagnosis. Therefore, it is imperative that pathologists should be well aware of its cytological features so as to avoid erroneous diagnosis and hence prevent unnecessary surgical interventions. We hereby, present a case of adenomatoid tumor of testis in a 41 year male diagnosed by FNAC and later confirmed by histopathological examination.

A 75-year-old man was diagnosed as having pancreatic ductal carcinoma containing remarkable lymphocytic and plasma cell infiltration, as revealed by the cytological examination of endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) specimen. The EUS-FNA specimen showed small amounts of atypical epithelium with noticeable lymphocytes and plasma cells. A pancreatic resection was performed, and the histopathological features showed an invasive pancreatic ductal carcinoma with autoimmune pancreatitis (AIP) lymphoplasmacytic sclerosing pancreatitis (LPSP)-like lesions. Most of the plasma cells were immunoreactive to anti-IgG4 antibody. EUS-FNA may be necessary for the differential diagnosis of AIP and pancreatic cancer, and close attention should be given to the presence of marked lymphoplasmacytic cells in EUS-FNA specimens while making the diagnosis.

Adult-type granulosa cell tumors (AGCT) account for 1-2% of all ovarian tumors and 95% of granulosa cell tumors. In AGCT, at the time of peritoneal washing, tumor cells are rarely seen to exfoliate and FIGO stage is raised from IA/IB or IIA/IIB to stage IC or IIC despite the absence of a gross intraepithelial tumor. Patients with positive peritoneal washing cytology must be followed up for pelvic recurrence and metastasis. A more sensitive cytologic evaluation, histopathologic correlation and immunohistochemical staining can advance our practice. Here, we describe a case of AGCT with the emphasis on cytologic features observed in specimens obtained from peritoneal washing fluid.

January-March 2013, 30(1):23-26
DOI
:10.4103/0970-9371.107508
PMID
:23661936
Background:
Fine needle aspiration cytology (FNAC) is a valuable adjunct to pre-operative screening in the diagnosis of thyroid nodules, and in most cases, it can distinguish between benign and malignant lesions.
Aim:
To study the cytology of neoplastic thyroid lesions to minimize surgical intervention and for confirmation of the diagnosis by histopathological study.
Materials and Methods:
100 cases of thyroid FNAC smears were analyzed and cyto-histopathological correlation was done in 47 cases. Galen and Gambino's method was used to calculate the sensitivity and positive predictive value.
Results:
Of the 100 cases, 90 were diagnosed as neoplastic lesions by FNAC and ten cases as non-neoplastic lesions, which turned out to be neoplasms on histopathological study. Among 100 cases, 47 were biopsied and subjected to histopathological study. The sensitivity of FNAC was 75.60%, and positive predictive value was 83.78% for malignant lesions.
Conclusions:
FNAC is a rapid, efficient, cost-effective, relatively painless procedure with a high diagnostic accuracy. It has high rate of sensitivity and positive predictive value in diagnosing thyroid neoplastic lesions. Hence, it is a valuable tool in the diagnosis and management of patients.

Langerhans cell histiocytosis (LCH) is a rare disease affecting predominantly children. The course of the disease varies, from spontaneous resolution to a progressive multisystem disorder with organ dysfunction and potential life-threatening complications. Diagnosis of LCH is often difficult and may be delayed because of its rarity and especially so if it occurs with unusual presentation. Fine needle aspiration cytology of a 4 year old male child, a case of LCH is presented with a purpose of highlighting the characteristic cytological features. A high index of suspicion, awareness of characteristic cytological features of LCH and its differential diagnoses is necessary. This can obviate the need of biopsy and electron microscopy. Immunohistochemistry if available can be performed on cytology smear and cell block.

Spindle cell lipoma masquerading as lipomatous pleomorphic adenoma: A diagnostic dilemma on fine needle aspiration cytology
S Agarwal, A Nangia, P Lalita Jyotsna, M Pujani
January-March 2013, 30(1):55-57

Spindle cell lipoma is a relatively uncommon benign adipocytic tumor that usually presents in subcutaneous fat of adult men. These are a rare form of lipoma, accounting for 1.5% of all lipomatous tumors, with a low rate of local recurrence and no risk of malignant behavior/dedifferentiation. Although few studies addressing the histological findings of spindle cell lipoma have been described, only a few descriptions of fine needle aspiration cytology (FNAC) findings have been documented in literature. We present a case of a 55-year-old male with a nodular swelling over left cheek (in the parotid region), which due to its location as well as prominent myxoid background prompted us to include the lipomatous salivary gland lesions in differential diagnosis. Our objective is to document and delineate the characteristic cytological features of spindle cell lipoma, which may permit a confident diagnosis on FNAC smears.

JS Nigam, V Misra, V Dhingra, S Jain, K Varma, A Singh
January-March 2013, 30(1):13-17
DOI
:10.4103/0970-9371.107506
PMID
:23661934
Background:
The nasal cavity and paranasal sinuses - including the maxillary, ethmoid, sphenoid, and frontal sinuses are collectively referred to as the sinonasal tract. Fine needle aspiration (FNA) of paranasal sinus lesions for early diagnosis of neoplastic lesions is difficult due to closed architecture, and only one study has been documented in the literature.
Aims:
To find the efficacy of intra-operative cytology and frozen section for frequently encountered tumor and tumor-like lesions of the nose and paranasal sinuses.
Materials and Methods:
Thirty cases were included in this study. The material for cytologic examination and frozen sections were taken per-operatively. Cytological smears were prepared by imprint/squash methods from the representative tissue pieces and stained with Leishman-Giemsa and Papanicolaou. Frozen section and paraffin-embedded section were stained with hematoxylin and eosin stain. A rapid opinion regarding the benign or malignant nature of the lesion and the type of tumor was given.
Results:
The sensitivity, specificity, and positive predictive value of imprint cytology, squash cytology, and frozen section were 100%, 100%, and 100%; 100%, 96.15%, and 80.0%; and 100%, 96.15%, and 80.0%, respectively. Overall diagnostic accuracy of imprint smears, squash smears, and frozen section was100%, 96.7%, and 96.7%, respectively. Imprint smears had better specificity as cells morphology could be more accurately appreciated.
Conclusions:
Intra-operative cytology and frozen section examinations of lesions of nose and paranasal sinuses are useful, quick, and reliable diagnostic technique for rapid diagnosis in the operation theatre and can be used as an adjunct to histopathology for better management of patients.

Intravascular papillary endothelial hyperplasia (IVPEH) is an unusual form of intravascular endothelial proliferation. Fine needle aspiration (FNA) diagnosis of IVPEH is quite challenging and only rare reports of the cytopathological features of this entity have been published. We report a case of a 55-year-old female patient who presented with a mass on her left jaw. FNA of the mass revealed pleomorphic polygonal and spindle cells. A preliminary (onsite) cytological diagnosis of suspicious for malignancy was rendered. Subsequent cell block showed delicate papillae composed of attenuated endothelial cells overlying collagenized cores. The endothelial cells were positive for CD34 and factor VIII, supporting the cytological diagnosis of IVPEH. Surgical excision confirmed the diagnosis. To the best of our knowledge, this is the first reported case of IVPEH diagnosed by preoperative FNA.

Fine needle aspiration cytology was performed in a 46-year-old female presenting with a breast lump and mammography suggesting a malignancy. The smears were cellular with cohesive clusters and scattered epithelial cells showing moderate nuclear pleomorphism and focal acinar formation. Stromal fragments, benign epithelial cell clusters and a few naked nuclei were noted in the background. Considering the clinical features, mammography findings as well as cytological features, a diagnosis of ductal carcinoma was suggested. Subsequent histopathological examination revealed it to be nodular sclerosing adenosis. The cytohistological correlation of this uncommon lesion, a potential pitfall in breast fine needle aspiration diagnosis which may lead to a false-positive diagnosis is discussed.

Paget's disease is a rare form of breast cancer often associated with an underlying ductal carcinoma
in situ
or invasive cancer. A 47-year-old female patient presented with bleeding from the left nipple since 4 months. Imprint smears from the lesion showed pleomorphic malignant epithelial cells in singles and in small clusters, many of them containing dark brown cytoplasmic pigment granules. There was no palpable breast lump or axillary lymph node enlargement. Based on the physical examination and cytological features, a diagnosis of malignant melanoma with a differential of Paget's disease of the nipple was made. Biopsy showed features of Paget's disease and immunohistochemistry was positive for HER-2/neu, negative for HMB-45 and S-100, thus confirming the diagnosis. This case has been reported to emphasize the fact that Paget's cells can contain imbibed brown cytoplasmic pigment and should not be mistaken for melanoma cells on cytology smears.

January-March 2013, 30(1):27-32
DOI
:10.4103/0970-9371.107509
PMID
:23661937
Background:
Scrotal ultrasound, though reliable in distinguishing between intratesticular and extratesticular lesions and characterizing them as cystic and solid, cannot distinguish benign from malignant pathology. Although fine needle aspiration cytology (FNAC) has proved to be of great diagnostic importance in testicular lesions, its scope in extratesticular lesions is largely unexplored.
Aim:
To evaluate extratesticular scrotal lesions cytologically and compare it with their clinical, radiological, and histological findings.
Materials and Methods:
Sixty five patients with extratesticular scrotal lesions were assessed clinically, radiologically, and cytologically. Histopathology was done in 45 cases where surgical exploration was undertaken. All the data were then analyzed and correlated.
Results
: Extratesticular lesions accounted for 72.2% of the scrotal swellings. Of these, the epididymis is most commonly involved (61.5% cases) with the commonest type of lesion being cystic (49.3% cases). Ultrasonography preferably with color doppler is highly useful for the evaluation of the scrotum. Apart from distinguishing extratesticular from testicular and cystic from solid lesions, it has an important role in identifying individual lesions, thus reducing the list of differential diagnosis. Fine needle aspiration cytology contributed to a definitive diagnosis in 47.7% cases. It helps classify cystic masses on the basis of their contents and defines the etiology of chronic inflammatory lesions, apart from corroborating with the clinico-radiological diagnosis. Histological evaluation was possible only in cases where surgery was performed and helps further define the diagnosis.
Conclusion
: Fine needle aspiration cytology is essentially non-traumatic and easy to carry out and should be a technique of choice for the study of scrotal pathology, main advantage being avoidance of delays in diagnosis.

Evaluation of the category high-grade squamous intraepithelial lesion in The Bethesda System for reporting cervical cytology
Subhalakshmi Mukhopadhyay, Sumit Ray, Supria Dhar, Ranjana Bandyopadhyay, Swapan K Sinha
January-March 2013, 30(1):33-35
DOI
:10.4103/0970-9371.107510
PMID
:23661938
Background:
High grade squamous intraepithelial lesion (HSIL) is a category of The Bethesda System (TBS) for reporting cervical cytology that is in vogue since the introduction of the said system in 1988 and it was not modified in 2001 modification of TBS. The term includes moderate dysplasia (CIN II), severe dysplasia (CIN III) and squamous cell carcinoma
in situ
. Terms like ASC-US used in TBS are being considered to be not very useful in the prediction about the possible behavior of the pathological status of the cervix. After more than 10 years of use the term HSIL also needs fresh evaluation as in this category two entities of potentially different outcome are clubbed.
Aims:
The aim was to find out whether it is justified to have a term like HSIL which includes different points of the spectrum of intraepithelial pathology of cervix from moderate hyperplasia through carcinoma
in situ
, all having different significance.
Materials and Methods:
In this study 619 cases of cervical cytology reported by TBS were evaluated by comparing them with biopsy reports of the same lesion for the assessment of the sensitivity, specificity and positive predictive value of HSIL as a category of diagnosis in TBS.
Results:
As a category, HSIL had the diagnostic sensitivity of 96.4%, specificity of 87.5%. The positive predictive value was 96.4%.
Conclusion:
HSIL as a diagnostic category shows a very good predictive accuracy, which implies that it provides a very high probability of the accurate diagnosis collectively of all the conditions in the disease spectrum from moderate dysplasia through
in situ
carcinoma. Hence, HSIL was found to be a very useful diagnostic category in TBS that conveys proper message to the clinician.

The integration of HR-HPV increases the expression of cyclins A and E in cytologies with and without low-grade lesions
MI Zubillaga-Guerrero, B Illades-Aguiar, MA Leyva-Vazquez, E Flores-Alfaro, E Castañeda-Saucedo, JF Muñoz-Valle, LC Alarcón-Romero
January-March 2013, 30(1):1-7
PMID
:23661932
Background:
Cyclin-A and cyclin-E are regulators of G1-S phase of normal cell cycle. Integration of human papilloma virus high-risk (HR-HPV) could alter this mechanism, and its overexpression has been associated with poor prognosis in cervical cancer.
Aim:
To determine the expression of cyclin-A and cyclin-E, types of HR-HPV and physical state of DNA in cytologies with the diagnosis of low-grade squamous intraepithelial lesion (LSIL).
Materials and Methods:
115 cytological specimens in liquid base (liquid-PREP
™
) were analyzed. 25 specimens were with no signs of SIL (NSIL) and without HPV; 30 with NSIL with low-risk HPV (LR-HPV); 30 with NSIL with HR-HPV; and 30 with both LSIL and HR-HPV. The expression of cyclins was evaluated by immunocytochemistry; and the detection of viral DNA was done by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLPs) for genotyping or sequencing of HPV. The physical state of HPV was evaluated by
in situ
hybridization with amplification with tyramide.
Results:
In the cytologies NSIL with LR-HPV, the expression of cyclin-A and cyclin-E was found respectively in 23.3% and 33.3% of the specimens. Among the specimens of NSIL with HR-HPV, 33.3% expressed cyclin-A and 40% cyclin-E, while 100% of the LSILs expressed the 2 cyclins. On the other hand, 100% of the samples NSIL with LR-HPV presented an episomal pattern. Of the specimens of NSIL with HR-HPV, 56.6% exhibited an episomal pattern, 23.3% integrated and 20%, mixed. Among the LSILs, 90% were mixed and 10% integrated.
Conclusions:
The cyclins A and E are present in the LSILs that occur predominantly in mixed state in the presence of HR-HPV.

Pleomorphic fibroma (PF) is a benign, polypoid, or dome-shaped cutaneous neoplasm with cytologically atypical fibrohistiocytic cells. We describe the cytomorphological features of PF retrospectively with histopathological diagnosis in a 38-year-old male who presented with 3 × 1.5 cm swelling in the soft tissues of the thigh for 6 months. This lesion is benign despite the presence of pleomorphic or bizarre cells. We review the differential diagnosis of PF with other mesenchymal tumors. To the best of our knowledge, cytomorphological features on fine needle aspiration cytology of this tumor are not yet documented in literature.

Anorectal smear in the diagnosis of anorectal adenocarcinoma
D Demirel, I Ramzy
January-March 2013, 30(1):52-54

The purpose of this case report is to point out the diagnostic value of cytologic smears in patients presenting with anorectal complaints, such as bleeding, pain or discomfort, which may suggest a neoplastic lesion. We present a case of a 64-year-old man with a 3 months' history of anal bleeding and pain during defecation. He was diagnosed as having hemorrhoids and a hemorrhoidectomy was performed. The patient developed an anal stricture postoperatively that required operative dilation. He continued to complain about anorectal pain for 2 months and a subsequent rectoscopy revealed the presence of tumor 5 to 7 cm above the dentate line. The tumor was resected laparoscopically and was reported as an adenocarcinoma. Rectal bleeding recurred 18 months postoperatively and a smear was procured from the anorectal mucosal surface for cytologic evaluation. A definitive diagnosis of adenocarcinoma was rendered based on cytologic and histologic examination of the material. To the best of our knowledge, this is the first case report of anorectal adenocarcinoma diagnosed by cytologic smear in the English literature.
