Resumen:
BACKGROUND: Schwannoma is a benign neurogenic tumor that affects peripheral nerves, it can occur in any soft tissue of the body; its cutaneous localization distal to the proximal interphalangeal joints is very infrequent. The clinical diagnosis of a sub ungual schwannoma can be complex due to its possible similarities with another solid subungual tumors, so that, subsequent to the indicated surgical excision the diagnostic must be confirmed by histopathology, having good prognosis because of its extremely rare local recurrence. CLINICAL CASE: A 56-year-old female patient, who had an asymptomatic volume increase in the first nail plate of the right hand of eight years of evolution, with maxi mum growth three years ago; She had a history of trauma with a hammer on the nail plate. A surgical procedure was performed with digital anesthetic block and complete avulsion of the nail plate, finding an encapsulated whitish subungual neoformation measuring 1.5 x 1.2 x 1.0 cm. CONCLUSIONS: Although subungual schwannoma is a rare benign tumor, it should be added to the list of differential diagnoses of subungual tumors, completing the diagnosis with imaging studies and confirming it by histopathological study. ©.
