Microcystic adnexal carcinoma is an unusual, locally aggressive tumor that recently has been recognized as a distinct clinicopathologic entity. It typically occurs on the face of young or middle-aged women and often requires extensive surgical excision to gain local control. A case involving the upper lip and columella of a young woman is described and the available literature reviewed. The difficult reconstructive challenge this lesion usually presents is illustrated in this patient who required upper lip and complete columellar reconstruction.
