Glomus tumor causing anterior thigh pain: a case report.

Glomus tumors are a rare, benign neoplasm and 75% exist in the subungual region. Extradigital glomus tumors are much more difficult to diagnose because of their atypical location and symptoms. Furthermore, if their symptoms are similar to neuropathic pain, the patient can suffer from misdirected treatment due to misdiagnosis.
