[Mixed tumor of the skin].
An 81-year-old woman presented with a skin-colored, slowly growing tumor on her right lower eyelid. The diagnosis of mixed tumor of the skin was confirmed after excision and histologic examination of the tissue, which demonstrated a characteristic histology and immunohistochemistry. The mixed tumor of the skin is a usually benign neoplasm believed to originate in sweat glands. It is composed of epithelial cells set in a mesenchymal matrix, showing apocrine differentiation. Immunohistochemical staining is positive for cytokeratin, CEA, EMA and S100.
