DefinitionThis section has been translated automatically.
Permanently dilated skin capillaries visible to the naked eye with a diameter of =/< 0.1 cm. Teleangiectasias are still visible to the naked eye from a distance of about 2 m.
Teleangiectasias disappear under moderate glass spatula pressure. They are listed together with reticular varicosities (>0.2cm), when localized to the lower extremity, in the CEAP classification under C1 (clinic) as signs of early cutaneous varicosis.
Teleangiectasia may be localized, disseminated, or systematized in the setting of vascular malformation.

ClassificationThis section has been translated automatically.
Six clinical forms are distinguished:
- Punctate telangiectasia
- Linear or sinusoidal telangiectasia
- Single branched telangiectasia
- Reticular branching telangiectasia
- Patchy, spatter-like telangiectasia (e.g. in progeressive scleroderma)
- Nevus araneus (spider naevus) with centrally pulsating vessel.
EtiopathogenesisThis section has been translated automatically.
as primary telangiectasias
- in the context of congenital vascular malformations
idiopathic without recognizable cause
secondary (or symptomatic) acquired telangiectasias
- exogenously induced telangiectasia (chronic UV exposure, long-term systemic or local corticosteroid therapy)
- monitor-like in systemic diseases (e.g. progressive scleroderma; liver cirrhosis)
- as a disease symptom in primary cutaneous diseases (e.g. rosacea)

Differential diagnosisThis section has been translated automatically.
Teleangiectasias are to be distinguished from veinctasias (phlebectasias). These have a larger calibre, are tortuous and are bluish or blue-red in colour. The most common phelbectasias are spider vein varicose veins, which occur more frequently in connective tissue weakness and CVI.
