Solitary Keratoacanthoma of the Scalp: A Case Report

This case report describes the first documented instance of a solitary keratoacanthoma (KA) on the scalp of a 57-year-old Saudi woman. KA, a rapidly growing skin tumor, can be mistaken for squamous cell carcinoma (SCC). The patient had a non-regressing nodule on her scalp, which was surgically excised and confirmed as KA with no malignancy. The wound healed well without complications or recurrence, but hair did not regrow at the site. This case emphasizes the need to distinguish KA from SCC and supports surgical excision as an effective treatment.
