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.
