Tufted angioma in the upper lip: A report of a case

Clinical examination revealed a nodular lesion, located on the vermillion of the upper right lip, close to the medial line with an ulcerated surface and hardened edges, predominantly brown in color with reddened and yellowed areas. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of the article.)

Microscopic analysis showing irregular nodules or tufts of capillary sized vessels in a “cannon ball” fashion deep within the reticular dermis and subcutaneous tissue (white arrows) (hematoxylin-eosin; original magnification 40×).

The black arrow shows endothelial cells exhibited dark nuclei and had grown into the interior of the vessels, and the white arrow shows peripheral cells had nuclei of greater volume palely stained with a polygonal pattern, reminiscent of pericytes (hematoxylin-eosin; original magnification 400×).

The white arrows show solid areas growing in an irregular fashion throughout the dermis (hematoxylin-eosin; original magnification 40×).
