AB - Keratoacanthoma (KA) is a low grade, rapidly growing skin tumor which is thought to originate from the pilosebaceous unit from hyperkeratosis of the infundibulum and are often thought to originate on hair bearing skin or sun exposed surfaces. There are very scarce reports demonstrating they may occur in other areas such as mucous membranes or soles of the feet. We present a rare case of palmar KA in a 65-year-old female with no known antecedent history. Surgical excision was performed with complete removal of the tumor. Following surgical excision, the pathology of the irregularly elevated 0.7 x 0.2 cm lesion revealed a keratoacanthoma. The patient remained without evidence of recurrence at one year follow-up. We believe there is only one other report of isolated palmar KA to date in the literature. We review relevant literature on hand KA.
