Background
Glomus tumors are rare, benign, vascular neoplasms arising from the glomus body. Although they can develop in any part of the body, they commonly do so in the upper extremities, most frequently subungual areas. They can be either solitary or multiple. Most typically they present as a small, round, bluish nodule visible through the nail plate with a classic triad of symptoms: hypersensitivity to cold, heightened pinprick sensitivity, and paroxysmal pain. Several tests can help in diagnosing these tumors with multiple imaging tools such as X-ray, magnetic resonance imaging, and ultrasonography. However, only histology can confirm the diagnosis. Complete surgical excision of the tumor is the only effective treatment to achieve pain relief and low recurrence rate.
Case presentation
We report here a rare case of a 54-year-old Moroccan Berber woman presenting with a 10-year history of a glomus tumor at an unusual site. Dermoscopy and histology were helpful to confirm the diagnosis.
Conclusions
We aim to discuss clinical, dermoscopical aspects of this tumor and surgical modalities. We also emphasize the importance of keeping this tumor in mind among the possibilities of differential diagnosis of painful digital nodules.
