Abstract

Tubular apocrine adenoma is a rare benign tumor occuring most often on the scalp. We examined a case of a 69-year-old female who had a well demarcated solid nodule on the scalp. Pathol Microscopically, the tumor was composed of lobules of tubular structures. The tumor lobules were surrounded by a stroma of dense fibrous connective tissue. The tubular structures were usually formed of two rows of epithelial cells. In some areas, the widely dilated tubular structures showed papillary projections into the cavities. Some epithelial cells showed liculoma on decapitation secretion into the cystic structure. Problems of differential diagnosis with other adnexal tumors are briefly discussed.
