Abstract

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.

Keywords: Schwannoma, Fingers, Subungual

Preoperative photographs views of the lesion (circle).

Fig. 2

Transverse (A) and longitudinal (B) ultrasonography images show 1.2×0.9×0.6-cm-sized well-defined, lobulated, round, and hypoechoic cystic mass at the radial side under the nail plate. (C, D) Color Doppler ultrasonography shows subtle flow signals around the hypoechoic area.

Fig. 3

well encapsulated and single-lobulated, yellowish-white colored mass. The ovoid mass was 1.2×1.0×0.5-cm-sized.

Fig. 4

Histopathologic finding of the lesion, showing the typical palisaded spindle cell pattern of a Schwannoma. Antoni A (large arrow) and B (small arrow) patterns were showed (H&E, ×200).
