Apocrine Adenocarcinoma Occurring on the Chin.

We report a case of adenocarcinoma affecting the chin of a 48-year-old man. The tumor showed signs of apocrine differentiation and had infiltrated the muscle. The patient had no history or clinical evidence of breast cancer. We made a diagnosis of cutaneous apocrine adenocarcinoma. Apocrine adenocarcinoma rarely arises in areas with scarce apocrine glands. We reviewed the literature on apocrine adenocarcinoma of the face in areas other than the eyelids and auditory canal, where specialized apocrine glands are present.
