`!Poikiloderma`! is a skin condition that consists of areas of `F33f`_`[hypopigmentation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Hypopigmentation]`_`f, `F33f`_`[hyperpigmentation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Hyperpigmentation]`_`f, `F33f`_`[telangiectasias`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Telangiectasias]`_`f and `F33f`_`[atrophy`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Atrophy]`_`f. Poikiloderma of Civatte is most frequently seen on the chest or the neck, characterized by red colored pigment on the skin that is commonly associated with sun damage.`:cite-ref-1[`F5bf`_`[1`#cite-note-1]`_`f]

>>Pathogenesis

The exact cause of poikiloderma of Civatte is unknown; however, extended sun exposure, namely the `F33f`_`[ultraviolet light`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Ultraviolet_light]`_`f emitted by the sun, is the primary factor.`:cite-ref-2[`F5bf`_`[2`#cite-note-2]`_`f]

>>Diagnosis

>>Treatment

Albeit difficult, treatment of poikiloderma of Civatte involves the delivery of multiple wavelengths of intense pulsed light (IPL) to the affected area.`:cite-ref-3[`F5bf`_`[3`#cite-note-3]`_`f]
