Abstract:

We present a previously undescribed, intravenously occurring papillary hemangioma of the lip in a 10-year-old girl. Maze-like anastomosing capillary loops were found within the numerous, dilated veins widely distributed in the submucosa. These peculiar endovascular papillae of bland endothelial cells plugged the lumens and bore a striking resemblance to the renal glomeruli. Thrombi or other associated vascular lesions could not be identified. Because of its histological similarity to endovascular papillary angioendothelioma-like tumor, we designate this tumor as endovascular papillary hemangioma.

Keywords: capillary hemangioma; endovascular papillary angioendothelioma; lip; papillary endothelial hyperplasia; pyogenic granuloma
