Epithelioid sarcoma. Report of a case with fine needle aspiration diagnosis
1Departments of Cytology and Histopathology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
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.
