Poikiloderma of Civatte is a condition affecting the skin. Many consider it to be a reaction pattern of the skin and not a disease. The term poikiloderma refers to the combination of atrophy, telangiectasia, and pigmentary changes (both hypopigmentation and hyperpigmentation). Poikilodermatous lesions may be seen in certain genodermatoses (Rothmund-Thomson syndrome, Bloom syndrome, dyskeratosis congenita), in connective tissue diseases (dermatomyositis, lupus erythematosus), in parapsoriasis/mycosis fungoides, and in radiodermatitis.
