Aspiration Cytology of Epithelioid Sarcoma - A Cese Report -

유상피 육종의 흡인 세포학 - 1예 보고 -

Cytologic features of the fine needle aspiration of metastatic epithelioid sarcoma are presented. The patient was a 48 year-old male who had been sufferring from recurrent and metastatic tumors of the right upper extremity for 6 years. The aspirate from the axillary mass cytologically consisted of isolated large polygonal cells with abundant, cyanophilic, slightly granular cytoplasm. Eccentrically located large round nuclei showed finely dispersed chromatin, small nucleoli, occasional convolution and folding of nuclear membrane, and frequent binucleation. Although both histologic and cytologic similarity of epithelioid sarcoma to squamous cell carcinoma is well known, findings of cyanophilic granular cytoplasm, convoluted nuclei, and binucleation appeared to be the differential points.
