Abstract

Hori nevus, also known as acquired bilateral nevus of Ota-like macules, is a form of dermal melanocytosis found most commonly in women of East Asian heritage. It presents as discrete brown macules on the bilateral cheeks which later coalesce into confluent grey-brown macules and small patches. Herein, we report a classic case of Hori nevus and discuss the histologic findings and differential diagnosis. We also review the proposed pathophysiology, genetic considerations, and treatment options.
