Microcystic adnexal carcinoma of the face treated with radiation therapy: A case report and review of the literature

Abstract

Background Microcystic adnexal carcinoma is a rare, locally aggressive neoplasm most commonly occurring on the face. Minimal data are available regarding the role of radiation therapy (RT). Methods Cases treated with RT from 2 comprehensive cancer centers are reviewed along with a review of the literature. Results Three patients with microcystic adnexal carcinoma of the face were treated with curative intent. One patient received RT as monotherapy. Two patients received postoperative RT (PORT). The patient receiving RT as monotherapy experienced excellent clinical regression, had an in‐field recurrence at 48‐month follow‐up, and is now without evidence of disease after reirradiation. Both patients receiving PORT are without evidence of disease. Conclusion PORT may improve local control in patients with microcystic adnexal carcinoma, and its use should be considered in patients with high‐risk features for local recurrence. RT as monotherapy should be considered when poor cosmetic outcome can be anticipated via standard surgical treatments. © 2011 Wiley Periodicals, Inc. Head Neck, 2012
