Poikiloderma of Civatte is a rather common, benign 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. Contact allergy may play a role in some cases.
