Generalized essential telangiectasia (GET) is a benign condition in which there are progressive, widespread, asymptomatic, blanchable telangiectasias. This condition primarily affects adult women, and the average age of onset is late 30's to late 40's, but pediatric cases have been reported. The limbs, especially distal extremities, are usually initially affected with gradual, proximal progression to more widespread involvement. Conjunctival involvement has also rarely been reported.

Most commonly, telangiectasias start distally and spread proximally in a symmetric pattern. The lesions can also be distributed in localized, diffuse, discrete, or confluent patterns. The affected areas are usually asymptomatic, but there can be associated tingling, burning, or numbness.

Generally, there are no associated systemic symptoms or bleeding; however, there have been reported cases of gastrointestinal bleeding secondary to gastric antral vascular ectasias.
