The cytologic and immunocytologic findings in a case of recurrent “proximal‐type” epithelioid sarcoma (ES) of the vulva are presented. This is a recently described neoplasm that differs clinically and morphologically from conventional ES. Cytologic smears showed a dissociated population of large, atypical neoplastic cells with bi‐ and multinucleated cells, abundant cytoplasm, and rhabdoid‐like morphology. Due to its different clinical management it must be differentiated from metastatic carcinoma and melanoma. From a practical perspective, its differentiation from other epithelial‐like sarcomas is less important. In conclusion the cytopathologic findings of “proximal‐type” ES show a good correlation with histopathology, permitting the diagnosis of recurrences and metastases. When accompanied by adequate clinical information and ancillary studies, a specific preoperative recognition seems possible. Diagn. Cytopathol. 2001;25:122–125. © 2001 Wiley‐Liss, Inc.
