Keratoacanthoma Right Lateral Canthus

In our case report, an 86 y.o. woman underwent excision of a right lateral canthus keratoacanthoma with Mohs surgery. The lesion recurred 2 months later spreading into the orbit and deep along the surface of the maxilla. She required a partial maxillectomy and orbital exenteration with post-operative radiation therapy. Forehead fasciocutaneous flap was used for reconstruction.
