Subungual glomus cell proliferation in the toe: a case report.

Glomus tumors are rare benign neoplasms. They typically present with a triad of severe pain, point tenderness, and cold sensitivity. Most glomus tumors will form well-circumscribed nodules, and excisional biopsy of masses detected by ultrasonography or magnetic resonance imaging of the lesion can relieve the symptoms. We describe a 30-year-old female patient with nontumorous glomus cell proliferation with clinical symptoms similar to those of glomus tumors. The lesion was treated by exploration and excision, with a satisfactory clinical outcome.
