The use of Mohs surgery in facial tumors in a patient with Darier's disease.

A case illustrating the need for the Mohs technique for removing basal cell carcinomas (BCC) in skin involved with Darier's disease is presented. Because of the erythema and scaling secondary to Darier's disease, defining the margins of the tumor clinically is impossible. Therefore, we recommend Mohs micrographic surgery for BCCs that occur in Darier's-involved skin.
