Keratoacanthoma of the Head and Neck

Abstract

Four representative cases of keratoacanthoma of the head and neck are presented; one of which contained squamous cell carcinoma at its base. Although keratoacanthoma has become recognized as a distinct clinical entity, its similarities to squamous cell carcinoma frequently result in difficult diagnosis. A discussion of the disease spectrum, diagnosis and management is presented. Prompt and complete surgical excision of head and neck keratoacanthoma is recommended.
