Interdigital neuroma in a patient with macrodactyly of the hallux

case report

Keywords: Neuroma, Foot deformities, congenital, Orthopedic surgery, Neurofibrosarcoma


A patient with macrodactyly of the hallux, returned 2 years after amputation of the distal phalanx, complaining of pain and swelling in the plantar foot. The Tinel, Moulder, and Gauthier signs were all present. Diagnostic hypotheses were: neuroma of the amputation stump, compressive neuroma, neurofibroma, or schwannoma. Histopathological diagnosis demonstrated that the tumor was a neuroma. This is a rare and unique case associated with macrodactyly, in which nerves tend to be hypertrophic. The location in the first intermetatarsal space is uncommon. The treatment proposed was resection of the entire involved nerve; symptoms improved and there was no relapse. Level of Evidence V, Therapeutic Studies; Expert Opinion.
