Aspiration Cytology of Epithelioid Sarcoma: A Case Report.: Kyung Ja Cho, Jung Youn Kim, Seung Sook Lee, Shin Kwang Khang; Korean J Cytopathol. 1996;7(1):84-87.

Abstract PDF: Cytologic features of the fine needle aspiration of metastatic epithelioid sarcoma are presente. 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.

Imprint Cytologic Features of Epithelioid Sarcoma: A Case Report.: Young Ran Shim, Joon Hyuk Choi; Korean J Cytopathol. 2004;15(1):65-69.

Abstract PDF: Epithelioid sarcoma is a malignant soft tissue neoplasm with an uncertain histogenesis. We report the imprint cytologic features of epithelioid sarcoma in the left shoulder of a 29-year-old male patient. Imprint cytologic findings showed dissociated and loose aggregates of anaplastic epithelioid cells on the necrotic, bloody, and inflammatory background. Tumor cells were round to polygonal shaped. Tumor cells had vesicular nuclei with abundant cytoplasm. The nuclei were irregular in shape and often eccentrically located. Some tumor cells were oval to spindle shaped. Binucleated and multinucleated cells were found. Intracytoplasmic vacuoles were present. On immunohistochemical stain, the tumor cells were positive for epithelial membrane antigen, vimentin, and CD34.
