A 29-year-old male patient complained subungual palpable mass with sharp pain. Ultrasonography showed a lobulated, hypoechoic, vascularized mass that was distinct from the surrounding soft tissue of 1.2×0.9×0.6 cm in size, probably a glomus tumor. Authors performed surgical excision and excisional biopsy, and pathological study was diagnosed schwannoma. Subungual schwannoma is very rare and have been reported as a painless mass. Authors report a case of painful subungual schwannoma mimicking glomus tumor on ultrasonography.
