A 59-year-old male working as a construction worker presented with an acute, rapidly growing dorsal hand mass after a direct, sharp penetrating injury to the hand. He was taken to the operating room for an excision biopsy and local flap coverage. Final pathology reports demonstrated well-differentiated squamous cell carcinoma, keratoacanthoma (KA) type. KA is common but has a varied presentation. The diagnosis and management are controversial but typical recommendations are wide excision for a tissue diagnosis and postoperative surveillance. Here, we present a rare report of an acute posttraumatic keratoacanthoma of the hand and a review of the literature.
