Aims and Objectives: To study the diagnostic utility of fine-needle aspiration cytology (FNAC) and immunocytochemistry in diagnosing primary malignant mixed Mullerian tumors (MMMT). Materials and Methods: A 3-year retrospective study carried out in a tertiary care hospital, which included all the gynecological patients who underwent USG-guided FNAC of their abdominopelvic masses. Observations and Results: Out of the 324 total cases, 05 (1.5%) were reported as primary malignant mixed Mullerian tumors. Out of these 05 cases, 03 were ovarian, 01 was uterine, and 01 involved both uterus and one-sided adnexa. The FNA smears from the masses revealed cytomorphological features of a biphasic neoplasm with elongated pleomorphic spindle cells and dispersed, focal attempted acinar pattern, thus indicating the possibility of MMMT. Immunocytochemistry was further carried out which showed both vimentin and cytokeratin positivity. The diagnosis was confirmed on subsequent biopsy and immunohistochemistry (without any histopathological-cytological discrepancy). Conclusion: Though the literature is replete in establishing a histo-pathological diagnosis of MMMT, the diagnosis on USG-guided FNAC has been rarely described. Emphasis should be made on the careful examination of small sarcomatous elements in smears. Utilization of cell block and immunocytochemistry with histopathological correlation should be done to avoid misdiagnosis.
