Abstract

This case report describes a patient who was presented with severe incisional pain following an uncomplicated total knee arthroplasty. There was suspicion for an incisional neuroma; however, excisional biopsy revealed an extradigital glomus tumor. The patient had immediate symptom resolution post-operatively. Clinicians should maintain a suspicion for the possibility of extra-digital glomus tumors at sites of prior extremity surgery, causing exquisite tenderness and pain.
