Generalized essential telangiectasia in Adult
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.
