Overview
Prognosis
The most common adverse effect is pain, which is usually associated with solitary lesions. Multiple tumors are less likely to be painful. In one report, a patient with more than 400 glomus tumors had thrombocytopenia as a result of platelet sequestration (ie, Kasabach-Merritt syndrome). Malignant glomus tumors, or glomangiosarcomas, are extremely rare and usually represent a locally infiltrative malignancy. However, metastases do occur and are usually fatal.
Patients who have surgery or radiation tend to do well.
Complications
- nail deformity, recurrence is a possible complication and may occur in up to 20% of cases.2 Recurrence is thought to be a result of incomplete excision or, in the case of late recurrence, development of a new lesion at or near the excision site. Excision of the capsule of the tumor is required to prevent local recurrence.[1]
