Hori's Nevus

Hori's Nevus (pronunciation: /ˈhɔːriːz ˈnɛvəs/), also known as Acquired Bilateral Nevus of Ota-like Macules (ABNOM), is a type of melanocytic nevus that is common in middle-aged Asian women.

Etymology

The term "Hori's Nevus" is named after the Japanese dermatologist, Dr. Masao Hori, who first described the condition in 1984. The term "nevus" is derived from the Latin word for "birthmark" or "mole".

Description

Hori's Nevus is characterized by blue or gray-brown patches on both sides of the face. Unlike Nevus of Ota, which is present at birth or appears in early childhood, Hori's Nevus typically appears later in life. The condition is benign and is not associated with any systemic diseases or malignancies.

Diagnosis

Diagnosis of Hori's Nevus is typically made based on clinical examination. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions such as Melasma or Postinflammatory hyperpigmentation.

Treatment

Treatment for Hori's Nevus is not necessary unless the individual is bothered by the cosmetic appearance. In such cases, treatments such as laser therapy or topical bleaching agents may be used to lighten the skin.
