Large cutaneous apocrine carcinoma occurring on right thigh aggravated after moxa treatment

Primary cutaneous apocrine carcinoma is a rare adnexal tumor of the skin that occurs mainly in the axilla, anogenital area while the scalp and the lower extremities, especially the thigh, are very unusual sites. However, clinical or pathologic characteristics have not been well established due to a paucity of this tumor. Herein, we report very unusual case of apocrine carcinoma present as a huge mass in the lateral thigh of 77-year-old woman, which was aggravated abruptly after an irritation by moxa treatment, with a brief review of the literature.
