Pitfalls in the diagnosis of epithelioid sarcoma presenting in an unusual site: A case report

The cytologic appearance of epithelioid sarcoma in fine-needle aspiration b iopsy cytology (FNABC) smears has not been extensively described We report a case of epithelioid sarcoma in a 55-year-old male who presented with nodu lar swellings in the abdominal wall and scrotum. The scrotal swelling was s ubsequently demonstrated to arise from the vas deferens. We highlight the c ytomorphologic, immunocytochemical, and histopathologic features of this ra re lesion in an unusual site, with particular emphasis on the dilemma encou ntered in the cytodiagnosis of this lesion.
