A congenital solitary glomus tumor

A glomus tumor is a kind of hamartoma that was first described by Masson in 1924. There are two major clinical forms of glomus tumor: solitary and multiple. Solitary glomus tumor which usually occurs in older age is characterized by a painful pink to red colored papule. A 2-week-old female infant presented to our department with a 1.3x0.4 cm sized tumor on her right foot, which had been present since birth. Histopathologic examination showed many vessels lined by thin endothelial cells and multiple rows of glomus cells. Ultrasonography of the foot revealed intense blood supply in the tumor bed. We diagnosed the patient with a congenital solitary glomus tumor, based on history, skin lesion, ultrasonography, and histopathologic findings. We report a case of a congenital, solitary glomus tumor in a 2-week-old female infant.
