Glomus Tumor

A glomus tumor (also known as a "solitary glomus tumor," "solid glomus tumor," or glomangioma is a rare benign neoplasm arising from the glomus body. Glomus tumors were first described by Hoyer in 1877, while the first complete clinical description was given by Masson in 1924.

As stated above, these lesions should not be confused with paragangliomas, which were formerly also called glomus tumors in now-antiquated clinical usage.

Familial glomangiomas have been associated with a variety of deletions in the glomulin gene, and are inherited in an autosomal dominant manner, with incomplete penetrance.
