Immunohistochemical studies of normal sweat glands, sweat gland tumors and extramammary Paget's diseases. II. Immunohistochemical studies of sweat gland tumors and extramammary Paget's diseases

Localizations of 18 antigens were analyzed in 41 cases with benign sweat gland tumors (13 with eccrine acrospiroma, 4 with eccrine spiradenoma, 2 with hidroacanthoma simplex, 9 with chondroid syringoma, 4 with syringocystadenoma papilliferum, 1 with tubular apocrine adenoma, 1 with papillary eccrine adenoma, 1 with apocrine cystadenoma, 1 with cylindroma, 5 with syringoma), 14 with malignant sweat gland tumors (7 with eccrine porocarcinoma, 3 with eccrine duct carcinoma, 3 with apocrine gland carcinoma, 1 with mucinous carcinoma) and 13 with extramammary Paget's disease. The results I obtained were compared with those in the normal sweat glands for determination of a differentiation of each tumor.
