Glomangioma
or glomovenous malformation is an autosomal
condition that is characterized by multiple venous
malformations in the skin. These low-flow vascular
birthmarks are often tender, blue, and nodular
appearing. Histopathologically, these lesions differ
from the typical
venous malformation ("cavernous
hemangioma") by the presence of numerous glomus cells. Glomus cells are immature smooth
muscle cells. For more information on
histopathological features of these vascular
anomalies click

Currently,
it is unknown if there is any difference on imaging
studies between a typical venous malformation
(cavernous hemangioma" and glomangioma).
