Unusual localization of a digital neurofibroma: About a case and review of the literature

Abstract

Neurofibromas are benign tumors of peri-nervous origin. may occur as a single lesion (solitary neurofibroma) or as part of a neurofibromatosis type 1. We present a case of a 44-year-old man with a painful neurofibroma on the dorsal surface of the 3rd right finger, revealed by a painful mass on its posterolateral aspect. Treatment was by excisional biopsy, with histopathological examination confirming the diagnosis. In the study by Lincoski et al, 24 benign nerve tumours accounted for 11.5% of the total number of soft-tissue tumours in the hand and forearm. Isolated neurofibromas are rare in the hand and normally grow slowly over many years. MRI provides precise information on the anatomical relationships of the tumour. Even with a correct diagnosis, the therapeutic decision must be carefully considered.
