[An immunohistochemical study of cutaneous tumors using an antibody to the breast cyst fluid protein (GCDFP-15)].
The antibody against a molecular weight 15,000 protein isolated from the breast cyst fluid (GCDFP-15) was applied to tissue from cutaneous tumors, especially to sweat gland tumors. This protein was purified from the breast cyst fluid; antisera was prepared in rabbits. Ninety six cases of cutaneous tumors were stained by the PAP method. Apocrine hydrocystoma, syringocystadenoma papilliferum, so-called mixed tumor of the skin, extramammary Paget's disease, microcystic adnexal carcinoma, and mucinous carcinoma of the skin were positively stained. Eccrine poroma, eccrine spiradenoma, syringoma, eccrine hydrocystoma, papillary eccrine adenoma, adenoid type of basalioma were negative. These observations indicate that the positively stained tumors have functioning seromucous cells, which are characteristic of apocrine gland cells and eccrine dark cells in the skin.
