Glomus tumor is a benign vascular tumor derived from modified smooth muscle cells of the glomus body. Although they can develop in any part of the body, they commonly do so in the upper extremities, most frequently in the subungual region of fingers. They can be either solitary or multiple. Extradigital glomus tumors are often misdiagnosed owing to their nonspecific clinical presentations and unusual locations. We report two cases of extradigital glomus tumor occurring at unusual sites such as knee and thigh.
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.
