Glomus tumor, also known as Glomangioma, originates in the neuromyoarterial glomus, a normal arteriovenous shunt abundantly supplied with nerve fibres and fulfilling a temperature-regulating function. The classic location of the glomus tumor is the subungual region, but it can occur elsewhere in the skin, soft tissues, nerves, stomach, nasal cavity, and trachea. There is some question as to whether this is a true neoplasm or simply a normal structure. Glomus tumor constitutes 1% to 5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness, and temperature intolerance, especially cold sensitivity. Glomus tumors are usually benign, but on rare occasions may exhibit an uncertain or malignant behavior as with glomangiosarcoma. In this article, we present a case of a 60-year-old female patient diagnosed with extradigital glomus tumor of the palm of right hand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
