Abstract:
Tubular apocrine adenoma(TAA) is a rare tumor characterized by papillary projection and apocrine differentiation. We report two cases of tubular apocrine adenomas. One patient was a 13-year-old male who had had a finger-tip sized asymptomatic cystic mass on his scalp since birth. Microscopically, the mass was composed of various sized cystic spaces and tubular structures lined by two layers of epithelia with nonvillous intraluminal papillary projections, decapitation secretions and connection with the epidermis. The other patient was a 55-year-old female who had had a 1.3x0.3cm sized dark red hard nodule on the left forearm since birth. Histopathologic finding showed a well circumscribed dermal neoplasm that predominantly consisted of multiple tubular structures lined by double layers of epithelial cells with decapitation secretions and intraductal papillary projections, and accompanied by underlying apocrine nevus. In both cases, immunohistochemical and enzyme studies showed positive findings in EMA, CEA, pancytokeratin, lysozyme, alkaline phosphatase, GCDFP-15.
