This case report highlights the diagnostic challenges and cytomorphologic features of epithelioid sarcoma presenting in an unusual site (vas deferens).
Raises caution for cytodiagnostic pitfalls in atypical sites; leaves open validation of site-specific criteria in larger series.
The cytologic appearance of epithelioid sarcoma in fine-needle aspiration biopsy cytology (FNABC) smears has not been extensively described. We report a case of epithelioid sarcoma in a 55-year-old male who presented with nodular swellings in the abdominal wall and scrotum. The scrotal swelling was subsequently demonstrated to arise from the vas deferens. We highlight the cytomorphologic, immunocytochemical, and histopathologic features of this rare lesion in an unusual site, with particular emphasis on the dilemma encountered in the cytodiagnosis of this lesion.
