The polymorphic apocrine nevus: a study of a unique tumor including carcinoembryonic antigen staining.
The apocrine nevus is a rare tumor. We report a 32-year-old man with a neck nodule, histologically an apocrine nevus displaying mature and immature apocrine structures in a distinctive pattern. The carcinoembryonic antigen staining was positive intracellularly only in the smaller luminal structures. We have named this unique tumor a polymorphic apocrine nevus.
