Can a glomus tumor be cancerous?

Malignant glomus tumors are exceedingly rare, comprising as high as 2.9% of all glomus tumors [5], and are often reported in the literature as single case reports from various institutions. Previously, glomus tumors that displayed unusual features were characterized as “atypical” or “malignant” [6].

What causes glomus tumor in finger?

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.

What is glomus tumor in the ear?
