A 23-year-old male presented with a hemispheric lump on his left inner thigh for about one year. Histological examination revealed a circumscribed oval neoplasm, consisting of cysts in various sizes. Tumor ceils in- cluded elliptical cells with eosinophilic cytoplasm and vacuolar nucleus, and polygonal cells with clear cyto- plasm and smaller, dark-stained, off-center nucleus. Immunohistochemical staining revealed positive for cytok- eratin (CK) 5/6 and epithelial membrane antigen (EMA) in tumor cells. S-100 protein and carcinoembry- onic antigen (CEA) were partially positive. Vimentin, smooth muscle actin (SMA) and calponin were nega- tive. The diagnosis was clear cell hidradenoma.
