[Acquired bilateral nevus of Ota]

Two patients, a 53-year-old woman and a 73-year-old man, with a variety of a naevus of Ota (naevus fuscocoeruleus ophthalmomaxillaris) are described. In both cases, blue-brownish pigmentation appeared symmetrically on the skin of the head. Neither ocular involvement, nor nasal or oral pigmentation was found. Histological examination revealed melanin-bearing, spindle-shaped, or irregularly shaped melanocytes located exclusively in the upper dermis.
