Telangiectasias

(Table 54-8) In order to distinguish the various types of telangiectasias, it is important to examine the shape and configuration of the dilated blood vessels

Linear telangiectasias are seen on the face of patients with actinically damaged skin and acne rosacea, and they are found on the legs of patients with venous hypertension and essential telangiectasia Patients with an unusual form of mastocytosis (telangiectasia macularis eruptiva perstans) and the carcinoid syndrome (see "Acne," above) also have linear telangiectasias Lastly, linear

telangiectasias are found in areas of cutaneous inflammation For example, lesions

of discoid lupus frequently have telangiectasias within them
