Epithelioid sarcoma. Report of a case with fine needle aspiration diagnosis

BACKGROUND: Epithelioid sarcoma is a rare type of soft tissue sarcoma affecting the extremities, particularly the hands and fingers. Though it is well described histopathologically, publications regarding its cytologic findings are limited. CASE: A 52-year-old woman presented with swelling of the left middle finger. Fine needle aspiration was performed. Smears showed oval to polygonal cells with epithelioid features. A diagnosis of soft tissue sarcoma with a possibility of epithelioid sarcoma was suggested. Histopathologic examination and immunohistochemistry confirmed the diagnosis. CONCLUSION: In the presence of classic cytologic findings, the diagnosis of epithelioid sarcoma can be suggested. Subsequent histologic examination and immunohistochemistry can confirm the diagnosis.
