Glomus Tumor

Glomus Tumor of the Finger

The glomus tumor is a rare benign neoplasm that arises from the neuroarterial structure called a glomus body, which accounts for 1 % to 4.5 % of tumors in the hand.  The average age at presentation is from 30 to 50 years of age, although can occur at any age. Typical time from onset of symptoms to the correct diagnosis is seven years.  The patient with glomus tumor seeks medical attention early, but the mass is frequently too small to be identified on physical examination. Although the classic triad of moderate pain, temperature sensitivity, and point tenderness has been described, these are nonspecific and not all may be present. Furthermore, because the mass is usually less than 7 mm in diameter, it is very difficult to palpate.  The most common site for glomus tumor is on the finger, (75% of lesions), but it can also be found on the foot as well as other areas of the body.  Women are three times as likely to be affected as men.  The pain of glomus tumor is intense and triggered by pressure or cold.  MRI exam will usually show the tumor.  X-rays will show any bony destruction caused by the tumor.  Treatment is surgical excision of the tumor.
