Morphea form basal-cell epitheliomas of the external ear are rare often poorly delineated clinically, present a high rate of recurrence caused by inadequate treatment, deeply invasive and destructive lesions, development over embryonic fusion plane and other anatomical particularity of the external ear. For tumor superior to 2 cm or recurrent lesion conventional excisions are very multilating on this part of face with a 10 to 15% of recurrent rates. The micrographic surgery with total microscopic control of excision described by Mohs which was not disponible for this case seems to be the treatment of choice for morphea form basal-cell carcinoma.
