A 26-year-old white woman had reticulate nonmelanocytic hyperpigmentation anomaly characterized by partially blanching red-brown papules and macules and a histologic picture of digitate epithelial budding proliferation with lightly pigmented rete ridges. Except for the classically described hyperpigmentation at the rete ridge tips, the patient has Dowling-Degos disease. This case of a reticulate nonmelanocytic hyperpigmentation anomaly is probably a variant of Dowling-Degos disease.
