Reticulate acropigmentation of Kitamura.

Seven cases of reticulate acropigmentation of Kitamura (RAPK) are described. All the patients were female and the pattern of inheritance suggested an autosomal dominant mode. Histologically, RAPK is characterized by epidermal atrophy, an increased number of basal melanocytes and the absence of pigmentary incontinence in the upper dermis. The present cases, from Asia, Africa and Europe, are the first to be described outside Japan.
