Reticulate hyperpigmentation of the skin can be seen in a variety of disorders, sometimes with significant clinical overlap.1 Genital lentiginosis can be seen as dark macules. We report 2 cases of reticulate pigmentation that cannot be classified in any of the conditions known to us to have been described.
