Microcystic Adnexal Carcinomas are malignant eccrine neoplasms that I rarely encounter in both my The Woodlands dermatology and Conroe dermatology offices.  Clinically, Microcystic Adnexal Carcinomas appear as a pearly or flesh colored papule or nodule on the face. The upper lip and nose are the most common areas to find Microcystic Adnexal Carcinomas.  Metastasis is very rare but they are locally aggressive and have a high rate of recurrence after excision.  This high rate of local recurrence is partly due to the predilection of Microcystic Adnexal Carcinomas to have perineural involvement.  The treatment of choice is Mohs surgery.
