Recurrent facial microcystic adnexal carcinoma and hair transplantation on scar site

Abstract

Key Clinical MessageMicrocystic adnexal carcinoma (MAC) is a rare kind of cutaneous neoplasm with a very aggressive local infiltration that destructs the affected tissues. Its rate of recurrence is high and it mostly involves the face and scalp regions and most of the patients get affected in the fourth or fifth decades of their life. Here in, we report a 61‐year‐old woman with a right‐sided eyebrow MAC lesion with recurrency. Total excisional surgery was performed. A‐T Flap surgery was applied on the involved area, and after a 2‐year period of follow‐up, with no recurrency, hair transplantation with follicular unit transplantation method was successfully performed on the scarred area. Although microcystic adnexal carcinoma is an uncommon neoplasm; dermatologists and ophthalmologists should consider it as a differential diagnosis, due to its aggressive local infiltration. Complete surgical excision and long‐term follow‐up must be applied to manage the disease. Also, hair transplantation with follicular unit transplantation technique can be considered as a beneficial method for treating scars resulted from MAC excisional surgery.
