Excision of a glomus tumor (painful tumor composed of specialized pericytes that are usually arranged in single encapsulated nodular masses that occur almost exclusively in the skin).

A glomus body is a component of the dermis layer of the skin, involved in body temperature regulation.

Glomus bodies are most numerous in the fingers and toes and they move blood away from the skin surface when exposed to cold temperature, thus preventing heat loss; and also, allowing maximum heat flow to the skin in warm weather to allow heat to dissipate.
