Idiopathic guttate hypomelanosis is a common leukodermic dermatosis of obscure origin, consisting of small 2- to 5-mm achromic or hypopigmented macules, mainly affecting the exposed upper and lower extremities. In a group of 400 consecutive dermatologic patients, idiopathic guttate hypomelanosis was much more prevalent in women than in men. However, in both sexes this prevalence became more common with advancing age. In another group of fifteen patients with idiopathic guttate hypomelanosis and fifteen normal controls matched by age, sex, and skin type, the following was found: A cause-effect relationship between chronic actinic exposure and the development of idiopathic guttate hypomelanosis could not be established by statistical studies. A family aggregation survey disclosed a higher prevalence of idiopathic guttate hypomelanosis in the family of patients with idiopathic guttate hypomelanosis than in the control group. Epithelial atrophy, patchy absence of melanocytes and melanin, flattening of the rete pegs, and basket weave hyperkeratosis were the most prominent histologic findings of idiopathic guttate hypomelanosis. Minigrafts of normal skin implanted in idiopathic guttate hypomelanosis lesions did not modify the achromic defects, whereas intralesional triamcinolone with or without grafts improved the appearance of these lesions.
