Abstract
- Subungual keratoacanthoma is a rare, benign tumor occurring mainly on the thumb of middle-aged Caucasians. It presents as a painful keratotic papule or nodule accompanied by consequential partial onycholysis and bacterial infections. Unlike keratoacanthoma of other sites, subungual keratoacanthoma is not spontaneously resolved and surgical interventions have been recommended for treatment. It also needs to be differentiated from other subungual lesions, especially squamous cell carcinoma. We describe a case of subungual keratoacanthoma, which was completely resolved with extraction of the nail followed by oral methotrexate(MTX) medication.
