Chapter 23 Angioma serpiginosum presents as a progressive vascular lesion on a woman’s leg. The ectatic vessels begin as minute puncta in clusters, but merge to form a serpiginous array. They often bleed freely when traumatized. Venous lakes are common on the lips and ears of older patients. They may appear very dark, but blanch easily when compressed. Subtypes include histiocytoid and epithelioid hemangioma. Histiocytoid endothelial cells are common.
