A 15-year mystery resolved: a large bone-boring glomus tumor mistaken as dermatitis

Glomus tumor (GT) is a rare, benign neoplasm of the glomus apparatus. Being most common in the subungual region, it often misdiagnosed with dermatological conditions. Severe tenderness, paroxysmal pain and cold intolerance symptomatically denote GT. Clinical tests such as Love’s pin test and Hildreth’s test assist in diagnosing the disease. X-ray, ultrasonography and magnetic resonance imaging can confirm the severity of the lesion. Complete surgical excision is the only treatment available for these subcutaneous nodules. A middle-aged male with a hand pain, who misdiagnosed for dermatitis over 15-year period, has identified as having a large bone-boring GT. Awareness of GT among healthcare professionals is a must to increase the quality of life of patients.
