Abstract
A 55-year-old woman was seen because of a pea-sized and slightly reddish nodular lesion of apocrine cystadenoma on the right hand. Histopathologically, the dermis contained one cystic space into which papillary projections extended. The space was lined by a double layer of cells. The inner surface was apocrine-type secretory epithelium with high columnar cells and peripheral elongated myoepithelial cells. 63 cases of apocrine cystadenoma have been reported in Japan and the usual location is the face, especially around the eyes. Our case is the first in Japan where apocrine cystadenoma occurred on the hand.
