Abstract

Microcystic adnexal carcinoma (MAC) is an infiltrative, rare adnexal tumor that arises from pluripotent cells with differentiation into both eccrine and follicular structures. We present a 43-year-old male patient with MAC in an atypical location on the dorsum of the left foot, situated on a previous scar. Despite its indolent behavior, it is locally aggressive and requires first-line surgical treatment, preferably Mohs surgery. We emphasize the importance of considering differential diagnoses and the need for deep biopsies to avoid diagnostic delays and to establish appropriate treatment.
