Medical Definition of Telangiectasia verrucosa
1. A discrete, pink to red telangiectasia having a tendency to undergo secondary epithelial changes, including acanthosis and hyperkeratosis. An underlying vascular abnormality is present in many cases. The term angiokeratoma is applied to a number of quite distinct conditions which share a common clinical presentation with asymptomatic hyperkeratotic vascular skin lesions and a histological combination of superficial dermal vascular ectasia.
