Poikiloderma
Poikiloderma ndi khungu lomwe limapangidwa ndi madera a hypopigmentation, hyperpigmentation, telangiectasias ndi atrophy. Poikiloderma imawoneka kwambiri pachifuwa kapena pakhosi, yomwe imadziwika ndi utoto wofiyira pakhungu womwe umayenderana ndi kuwonongeka kwa dzuwa.
☆ Muzotsatira za 2022 Stiftung Warentest zochokera ku Germany, kukhutitsidwa kwa ogula ndi ModelDerm kunali kotsika pang'ono kusiyana ndi kuyankhulana kwa telemedicine komwe kulipiridwa.

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.
