NEVUS OF HORI
AT A GLANCE
Acquired circumscribed hyperpigmentation in the
form of symmetrical pinhead-sized macules on the
malar region of the face.
Noted mainly in Asian populations.
Often coexists with other pigmentary conditions
like melasma and flat seborrheic keratoses.
Best treated with quality-switched Nd:YAG lasers.
Nevus of Hori was first described in 1984 as acquired
bilateral nevus of Ota–like macules (ABNOM) or
acquired dermal melanocytosis.80
EPIDEMIOLOGY
It is a common condition noted in nearly 1% of the
Asian population, particularly the Chinese and
Japanese population. It is more common in females
and appears in the third to fifth decades of life.
CLINICAL FEATURES
Nevus of Hori consists of blue-brown to slate-gray
hyperpigmented macules ranging from pinhead size
to a few millimeters in diameter (Fig. 77-18). Lesions
are found on the face with predilection for the malar
