Acquired bilateral nevus of Ota-like macules

Abstract

A 41-year-old woman presented with a 10-year history of grey-brown macules bilaterally on lateral forehead, temples, and malar aspects. Histopathologic examination showed dermal melanocytosis. Acquired bilateral nevus of Ota-like macules (Hori's nevus) is a condition usually found in middle-aged women of Asian descent. Pathogenesis is unknown, and effective treatment has been achieved with pigment-specific lasers.
