PMID
:21897540
Background:
Fine needle aspiration cytology (FNAC) of oral and maxillofacial region has not been widely utilized for diagnosis due to diversity of lesion types, heterogeneity of cell populations and difficulties in reaching and aspirating these lesions.
Aim:
Our aim was to demonstrate the effectiveness of this cheap and simple procedure for the diagnosis of tumor and tumor like lesions of oral and maxillofacial region. In addition, we sought to highlight probable causes of errors in the cases showing lack of correlation between cytological and histological diagnoses.
Materials and Methods:
The study was conducted on 50 patients of all age groups with various palpable lesions in the oromaxillofacial region. A comparison between cytological and histological diagnosis was done wherever biopsy material was available.
Results:
The rate of unsatisfactory FNA was 4%. There were six false negative cases but no false positive case. The sensitivity of our study ranged from 77.7 to 75% including and excluding the suspicious cases, respectively. Specificity and positive predictive value was 100%.
Conclusion:
FNAC is a minimally invasive, highly accurate and cost-effective procedure for the assessment of patients with oromaxillofacial lesions. When applied in a proper manner, FNAC can help avoid a surgical biopsy in many cases.

Sumit Mitra, Suchandra Ray, Pradip K Mitra
July-September 2011, 28(3):108-110
DOI
:10.4103/0970-9371.83465
PMID
:21897543
Aims:
This study was taken up with the aim to investigate the pattern of supraclavicular lymphadenopathy among patients presenting to our tertiary care institution, evaluate the diagnostic efficacy of fine needle aspiration cytology (FNAC), and analyze the diagnostic pitfalls.
Materials and Methods:
A total of 215 patients were subjected to FNAC of supraclavicular lymph nodes over a three-year period (August 2006 to July 2009). Since in 18 patients as either the aspirate was inadequate or the opinion was equivocal, we analyzed the remaining 197 cases.
Results:
Malignant pathology accounted for 79.7% (157/197) of the cases. These were mostly cases of metastatic squamous cell carcinoma (79/197, 40.1%), adenocarcinoma (47/197, 23.9%), small cell carcinoma (12/197, 6.1%) and lymphoma (10/197, 5%). There were 28 (14.2%) cases of tuberculosis. Out of these 197 patients, 92 patients were biopsied. The opinion based on FNAC was erroneous in 6 cases but corroborated with the final histopathology findings in the remaining 86 cases.
Conclusion:
FNAC is an excellent first line of investigation; and when used with a proper combination of experience and diligence, it can greatly reduce the number of errors.

Rosai-Dorfman disease, that is, sinus histiocytosis with massive lymphadenopathy is a benign systemic proliferative disorder of histiocytes. The typical clinical presentation of the disease includes bilateral painless massive lymphadenopathy, fever and polyclonal hypergammaglobulinemia. Extranodal involvement is present in only a few cases and skin lesions are the most common form of extranodal disease. However, purely cutaneous Rosai-Dorfman disease is uncommon. In this study, we describe a 10-year-old child presenting with bilateral ocular involvement.

Morphology to morphometry in cytological evaluation of thyroid lesions
S Shanmuga Priya, Sandhya Sundaram
July-September 2011, 28(3):98-102
DOI
:10.4103/0970-9371.83462
PMID
:21897541
Aim:
To evaluate the cytomorphometric features in fine needle aspiration cytology (FNAC) of thyroid lesions.
Materials and Methods:
FNAC of 36 thyroid cases was reviewed. The study included 10 cases each of follicular lesion, adenomatous goiter, papillary carcinoma, 4 cases of medullary carcinoma and 2 cases of anaplastic carcinoma. Their ages ranged from 28 to 50 years, and there were nine females and one male. Morphometric analysis was done on aspiration smears from 36 thyroid lesions. Hematoxylin and Eosin stained smears were examined using image analyzer Proplus V software. Morphological parameters measured included mean nuclear diameter, mean nuclear perimeter, mean nuclear area, circular rate, largest to smallest dimension ratio (LS ratio) and coefficient of variation of nuclear area (NACV).
Statistical Analysis:
Statistical evaluation was carried out using the analysis of variance (ANOVA) test for the five variables, both within the group and in between the groups. The result was considered significant when
P
< 0.05.
Results:
The follicular carcinomas had higher LS ratio than patients with adenomatous goiters. Mean nuclear diameter and the mean nuclear perimeter were higher in anaplastic carcinomas when compared to other subtypes and were the least for follicular neoplasms.
Conclusion:
When correctly applied, quantitative estimation of cytological nuclear features can play an important role in preoperative assessment and can complement morphological features in thyroid lesions.

Radio-pathological diagnosis of hepatobiliary ascariasis: A rare entity
Indranil Chakrabarti, Amita Giri, Anuradha De, Asit Chandra Roy
July-September 2011, 28(3):114-116
DOI

Ascariasis is the commonest helminthic infection in humans, caused by the nematode
Ascaris lumbricoides
. The adult worms usually reside in the small intestine. Rarely, they migrate into the bile duct and pancreatic ducts, but involvement of the gall bladder and/or liver parenchyma is extremely rare. Here, we describe a case of a 32-year-old woman who presented with fever, anorexia, right upper quadrant pain and mild hepatomegaly. Ultrasonography revealed a liver abscess and a concurrent moving adult worm in the gall bladder. Fine-needle aspiration cytology (FNAC) from the liver abscess showed presence of fertilized eggs of
Ascaris lumbricoides.
A diagnosis of gall bladder and hepatic ascariasis was made. The patient responded well to conservative management. Ascaris-induced liver abscess with concurrent living adult worm in gall bladder has rarely been reported. Ultrasonography and FNAC are important diagnostic modalities for detection of such lesions. Conservative management appears to be the treatment of choice for hepatobiliary ascariasis.

Fine needle aspiration cytology of epididymal nodules
Vinaya B Shah, Tanuja M Shet, Shilpa K Lad
July-September 2011, 28(3):103-107
DOI
:10.4103/0970-9371.83463
PMID
:21897542
Background:
The incidence of non neoplastic lesions are much more common in epididymis. Clinically, epididymal nodules are easily accessible to fine needle aspiration cytology (FNAC) procedure. There are very few literature reports documenting the role of cytology in evaluation of epididymal nodules. Thus, we studied patients presenting with palpable epididymis nodules in the out patient department (OPD) from a tertiary care general hospital.
Aim:
This study is aimed to put forth the diagnostic utility of FNAC in palpable lesions of epididymis.
Materials and Methods:
A total of 40 palpable epididymal nodules were aspirated as a routine OPD procedure as part of this study. Smears were fixed in isopropyl alcohol and air dried. In all the cases, wet fixed papanicoloau stained and air dried giemsa stained smears were studied. Zeihl Neelsen stain was performed in cases which yielded caseous aspirate.
Results:
Except for two cases of adenomatoid tumor of epididymis all other lesions were nonneoplastic and included 14 cases (35%) of tuberculous granulomatous inflammation, 10 (25%) cystic nodules (9 spermatoceles and 1 encysted hydrocele), 5 (12.5%) of nonspecific inflammations, 3 (7.5%) filarial infection, 3 (7.5%) sperm granulomas and 3 (7.5%) adenomatous hyperplasia of rete testes. Except for the two tumors, one adenomatous hyperplasia and one tuberculous lesion, no other lesion was excised. Follow up and response to therapy was available in 78% patients and resolution indicated appropriateness of the diagnosis.
Conclusions:
Thus, as most of the lesions in epididymis are non neoplastic responding to medical line of treatment and FNAC served to aid diagnosis of non specific inflammation and avoid surgical excision in most cases.

Genital tuberculosis is fairly common in Indian women due to high prevalence of pulmonary tuberculosis in the general population. Histopathological diagnosis is invaluable but often, diagnosis can be made with reasonable accuracy by Papanicolaou (Pap) smear test if the index of suspicion is kept high. Also, genital tuberculosis is considered to be more common in patients less than 40 years of age and rare after menopause. We describe two cases of cervical tuberculosis in patients over 40 years of age, including a postmenopausal case, diagnosed by smear tests and later confirmed by histopathology and bacteriology. The differential diagnoses as well as problems encountered in the diagnosis of a tuberculous lesion in Pap smears are also discussed.

Extramedullary hematopoeisis (EMH) occurs when function of the bone marrow is insufficient or destroyed. We report a case of lymph nodal mass in a young patient, diagnosed on fine needle aspiration cytology (FNAC) as infiltration by leukemia along with features of EMH. FNA smears from axillary lymph node revealed lymphoblasts with hand mirror cell and teat cell morphology. Also seen were occasional megakaryocytes and metamyelocytes.

Rhabdomyosarcoma (RMS) is an aggressive malignant soft tissue tumor that arises from primitive striated muscle cells called rhabdomyoblasts. RMS is a rare tumor in adults, and involvement of the sinonasal area is extremely rare, comprising only 1.5% of all reported head and neck RMSs. Alveolar RMS, mainly seen in adults, has the worst prognosis. Incidence of lymph node metastases is more common in this type compared with the other forms. Fine needle aspiration cytology (FNAC) has been used extensively in the diagnosis of metastatic malignancies. However, metastatic soft tissue sarcomas are often overlooked, primarily due to the low frequency with which they occur. Here, we report a rare case of metastatic alveolar RMS in the cervical lymph nodes of an 18-year-old girl that was detected by FNAC. After 6 months, the patient came with a huge mass involving the nasal vestibule and the upper lip. Histology of both the main mass and the lymph nodes revealed alveolar RMS.

PMID
:21897544
Background:
Although open surgical biopsy is the 'gold standard' for diagnosis of palpable breast lesions, in recent years two types of minimally invasive breast biopsy techniques, core needle biopsy and fine needle aspiration biopsy (FNAB), have become established for the diagnostic evaluation of palpable breast lesions.
Aims:
This study was undertaken to evaluate the clinical effectiveness of FNAB as a first line diagnostic procedure in the management of patients with breast lumps in University College Hospital (UCH), Ibadan, using the suggested thresholds for cytology performance as recommended by the United Kingdom National Health Services Breast Screening Programme (NHSBSP).
Settings and Design:
A 10-year retrospective cohort study carried out in the Pathology Department of UCH.
Materials and Methods:
All FNAB and histologically diagnosed cases of breast lesions in the pathology department between January 1996 and December 2005 were reviewed. The cytological diagnoses were then categorized into one of five diagnostic categories in accordance with the recommendations of the NHSBSP.
Results:
The positive predictive value for malignancy was 99.3% with a complete sensitivity of 97.7% and specificity (full) of 94.2%.
Conclusions:
The high quality assurance measures obtained in this study affirms FNAB as a clinically effective diagnostic procedure for breast lesions.

Neoplastic urothelium has the capacity to demonstrate enormous plasticity. A variety of unusual morphological variants of urothelial carcinoma have been described. Micropapillary variant of urothelial carcinoma is a rare and recently described bladder tumor, associated with poor prognosis. We present the cytological features of micropapillary urothelial carcinoma in a 65-year-old man with bladder mass. The cytological features include tightly cohesive clusters of micropapillary component admixed with urothelial carcinoma. Histopathological sections showed small nests of tumor cells residing within the lacunae. Establishing a diagnosis of micropapillary urothelial carcinoma indicates a high-grade and high-stage tumor with poor outcome, requiring an aggressive therapy. It is thus important for the cytopathologist to recognise micropapillary variant of urothelial carcinoma, for early and better management of patients with bladder tumor.

We report a case of typical carcinoid of the lung in a 60-year-old human immunodeficiency virus (HIV)-positive man diagnosed on brush cytology smears. Bronchial carcinoids are rare tumors, accounting for 1% to 2% of all lung tumors. Although the exact incidence in HIV-infected individuals is not known, the paucity of their documentation in the literature indicates that they may be equally rare. Cytological diagnosis on brush smears is rarely documented as the tumor is covered with mucosa and cellular yield is often not good. In this case, bronchial brushings showed distinctive cytological features of typical carcinoid. The awareness of its characteristic cytological features and differential diagnosis is required for an accurate diagnosis. Clinical awareness that non-acquired immunodeficiency syndrome (AIDS)-defining cancers can also occur in HIV-infected individuals in the context of the prolonged survival in the antiretroviral era is equally important. This case emphasizes the clinical importance of a broad differential diagnosis for lung lesions in HIV-positive patients.

Metastatic thyroid carcinoma is clinically silent and found only at autopsy in most instances. Renal cell carcinoma (RCC) is the most common and constitutes 56% of all secondary malignancies. However, preoperative distinction between primary and secondary thyroid neoplasms is often challenging. Fine needle aspiration is helpful in establishing a correct preoperative diagnosis. A local surgical resection is curative if prompt preoperative diagnosis is established. We hereby report a case of isolated metastatic RCC to the thyroid in a 65-year-old woman, diagnosed by fine needle aspiration cytology and later confirmed with histopathological examination.

Intracranial meningiomas are not often aspirated unless they erode the skull and present as swelling in the head and neck region. We describe the cytologic findings of fine needle aspiration cytology in a clear cell variant of intracranial meningioma presenting with swelling in the left parietal region of the scalp in a 45-year-old woman. The diagnosis was confirmed by histopathology. Clear cell meningioma is characterized by patternless sheets of clear polygonal cells. Clear cell meningioma is a rare distinctive cytological subtype of meningioma with high recurrence rate and increased mortality, which necessitate frequent follow-up after surgical excision. The recognition of clear cell meningiomas is important here and should be distinguished from other clear cell lesions of the scalp. If clear cell epithelial neoplasm is encountered on fine needle aspiration, it is reasonably possible to provide at least a differential diagnosis of meningioma based upon the focal whorls, sparce vascularity on low magnification, along with the presence of pseudoinclusion and inconspicuous nucleoli at high magnification.
