[Pigmented actinic keratoses].
Four cases of pigmented solar keratoses are reported. The brownish pigmented lesions on sun-exposed skin are clinically similar to lentigo simplex, lentigo senilis, lentigo maligna and pigmented seborrhoic keratosis. The surface is rather rough. Histologically, in addition to characteristic findings of solar keratoses, melanin can be found within the lower epidermis and within melanophages in the upper dermis (incontinence of pigment).
