Hori’s nevus, also known as acquired bilateral nevus of Ota-like macules (ABNOM), is a dermatological condition characterized by blue-gray or brownish patches on both cheeks. Unlike the nevus of Ota, Hori’s nevus is acquired rather than congenital (present at birth), typically appearing in adulthood (often in the third or fourth decade of life). These pigmented macules are most commonly observed in individuals with darker skin types, particularly those of Asian descent.
Common treatments include:
Laser therapy
Q-switched and Pico lasers such as the CURAS or PicoWay are utilized. The wavelengths utilized are chosen based on the depth of pigment seen in these lesions. These lasers target the pigmentation which is shattered or broken up using sound or acoustic energy.
These nevi commonly occur in those with darker or challenging skin types for laser and involve higher laser energy settings. This comes with the risk of causing pigment change including both hypo (reduction) and hyper (increased) pigmentation including Post inflammatory pigmentation. This may settle over time and/or may improve more quickly with treatment.
For more details on these pigment lasers see our CURAS and PicoWay pages.
These can be challenging lesions to treat and consultation with a dermatologist to assess and discuss an individual’s specific case, assess the best course of action and determine the most suitable treatment path.
