Poikiloderma
Is riocht craiceann é Poikiloderma atá comhdhéanta de réimsí hipipigmentation, hyperpigmentation, telangiectasias agus atrophy. Is minic a fheictear poikiloderma ar an cófra nó ar an muineál, arb é is sainairíonna é lí daite dearg ar an gcraiceann a bhaineann go coitianta le damáiste gréine.
☆ I dtorthaí 2022 Stiftung Warentest ón nGearmáin, ní raibh sástacht na dtomhaltóirí le ModelDerm ach beagán níos ísle ná mar a bhí le comhairliúchán teileamhíochaine íoctha.

Poikiloderma of Civatte (PC) is a rather common benign dermatosis of the neck and face, mainly affecting fair-skinned individuals, especially postmenopausal females. It is characterized by a combination of a reticular pattern of linear telangiectasia, mottled hyperpigmentation and superficial atrophy. Clinically, it involves symmetrically sun-exposed areas of the face, the neck, and the V-shaped area of the chest, invariably sparing the anatomically shaded areas. Depending on the prevalent clinical feature, PC can be classified into erythemato-telangiectatic, pigmented, and mixed clinical types. The etiopathogenesis of PC is incompletely understood. Exposure to ultraviolet radiation, hormonal changes of menopause, contact sensitization to perfumes and cosmetics, and normal ageing have been incriminated. The diagnosis is usually clinical and can be confirmed by histology, which is characteristic, but not pathognomonic. The course is slowly progressive and irreversible, often causing significant cosmetic disfigurement.
