An 18-year-old male patient presented with brownish, slightly atrophic, reticulated macular lesions on the dorsal parts of hands and feet since childhood, which were characteristic manifestation of reticulate acropigmentation of Kitamura.
At about thirteen years old age, he noted multiple deep brownish, freckle-like macules on the scrotum. Histopathologic findings of a scrotal lesion were compatible with those of Dowling-Degos disease, such as epidermal acanthosis, elongation of
rete
ridges and hyperpigmentation of the prickle and basal cell layer.
