Small Red Nodule on the Leg of a Young Woma
DIAGNOSIS: Microvenular hemangioma.
The microscopic examination revealed a superficial and middermal haphazard infiltrate of collapsed small vascular structures extending between collagen bundles. These vessels showed irregular branching and consisted mostly of plump endothelial cells. Focally, some of the vessels had more visible lumens, giving a sinusoidal appearance. Significant atypia and mitotic figures were not observed.
