[Progressive disseminated essential telangiectasia with conjunctival involvement].

BACKGROUND: Widespread idiopathic telangiectasia (generalized essential telangiectasia) is a rare skin disorder characterized by the development and gradual spreading of telangiectases. The condition tends to affect women in their midthirties. For no apparent reason telangiectases start to appear to the lower extremities and progress steadily to involve the skin of the trunk, the arms, and the face. General health is not affected by the condition and standard laboratory tests consistently yield normal results.

CASE REPORT: In February 1997 a 78-year-old lady was admitted for treatment of cataracta corticonuclearis of her left eye. Complete ophthalmological and dermatological examinations were performed. She presented marked conjunctival telangiectases of both eyes and widespread cutaneous telangiectases involving her face, trunk, arms, and legs. Complete blanching of lesional skin was observed on diascopy. The Rumpel-Leede-test was normal. Cutaneous and conjunctival changes appeared not to be associated with internal disease or bleeding abnormalities.

DISCUSSION: The patient presented here shows widespread idiopathic telangiectasia with marked conjunctival involvement. Ocular changes rarely have been reported in patients with generalized essential telangiectasia to date. Concomittant conjunctival and cutaneous telangiectases may be seen in other conditions such as hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber disease) and ataxia telangiectasia (Louis-Bar syndrome). The former shows an associated bleeding abnormality and is transmitted autosomal dominantly. The latter presents associated neurological signs such as cerebellar ataxia, strabism, nystagmus, apraxia, and mental retardation.
