What is a glomus tumor?
Glomus tumors, or paragangliomas, are slow-growing, usually benign tumors in the carotid arteries (major blood vessels in your neck), the middle ear or the area below the middle ear (jugular bulb). Glomus tumors are most often benign; however, they can cause significant damage to surrounding tissues as they grow.

What are Glomus Tumors?
A Glomus Tumor is rare, usually benign, soft tissue neoplasm. The glomus apparatus (or glomus body) is a part of the dermal layer of the skin and is thought to aid in temperature regulation. When exposed to cold temperatures, the glomus body moves blood away from the skins surface to reduce heat loss. While they are located all over the body, glomus apparati are found in higher concentrations in the fingers and toes. Abnormal growth of a glomus body results in Glomus Tumors.

How are Glomus Tumors diagnosed?
Glomus Tumors often require a specialist for accurate diagnosis. Upon examination the mass may appear as a bluish lesion under the nail or in the fingertip pulp. There may be an abnormal ridge in the nail, swelling at the tip and the nodule will be tender to touch. X-rays may show deformity or erosion in the distal phalanx if the mass is long standing, otherwise the films may appear normal. MRI (magnetic resonance imaging) is the gold standard for diagnosis.

In the case of fingers, where they most commonly occur on hands, it is very important that the doctor carefully outline the area of the tumor so that the incision is done precisely and carefully, and the surrounding tissues are not excised in addition to the body of the tumor. Complete removal of the glomus body is key to making sure that the tumor doesn’t recur.
