Infiltrating lipoma of the proper digital nerves.

Lipomas are one of the most commonly encountered benign soft tissue tumors. Their frequent occurrence and exact anatomic distribution in the hand and upper extremity have been well documented. A review of the current literature shows that these lesions are most often asymptomatic and occur only rarely with the fingers. Our recent experience has been at variance with this is that we have encountered two patients with symptomatic infiltrating lipomas of the proper digital nerves. The following report documents the clinical presentation, treatment, and postoperative course of these patients.
