Pathogenesis

The exact cause of poikiloderma of Civatte is unknown; however, extended sun exposure, namely the
ultraviolet light Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nanometer, nm (with a corresponding frequency around 30 Hertz, PHz) to 400 nm (750 Hertz, THz), shorter than that of visible light, but longer than ...
emitted by the sun, is the primary factor.


Diagnosis


Treatment

Albeit difficult, treatment of poikiloderma of Civatte involves the delivery of multiple wavelengths of intense pulsed light (IPL) to the affected area.PubMed.go
