The glomangioma in the differential diagnosis of vascular malformations.

Glomus tumors develop from a thermoregulatory unit called the glomus body which is found in high density within the digits of both the hands and feet. To note, even though less frequently, these tumors can present in extradigital locations. Usually it presents as a small, 1-cm bluish nodule. Glomangioma (multiple glomus tumors) is to be differentiated clinically from the more solitary glomus tumor on the basis of larger size and prominent vascular markings. Although glomangioma is described in literature, the major textbooks of plastic surgery fail to mention it. A report of an unusual case of a large glomangioma in the shoulder of a 13-year-old female is presented. Clinical picture, investigation, surgical treatment, and pathology of this lesion are discussed.
