Using immunohistochemical methods, we investigated the distribution of epithelial membrane antigen (EMA) on the normal eccrine gland, eccrine poroma and hidroacanthoma simplex. Granular membrane-associated reaction of EMA was detected on the outer cells of both the intraepidermal and the upper portion of intradermal eccrine ducts, as well as on the luminal surfaces and intercellular canaliculi of eccrine glands. Clear immunolabeling was also present in the tumor cells of eccrine poroma and hidroacanthoma simplex. Thus, it is suggested that the constituent cells of these tumors originate from the outer cells of the intraepidermal and/or the upper portion of the intradermal eccrine ducts. There was no immunolabeling for EMA on the tumor cells of seborrheic keratosis and basal cell carcinoma. Immunohistochemical staining for EMA is a useful tool for the diagnosis of skin appendage tumors.
