What Is Hori Nevus?

Hori nevus is a type of acquired dermal pigmentation that appears as blue-gray, brown-gray, or slate-colored patches on the face.

It is also called:

• Acquired bilateral nevus of Ota-like macules
• ABNOM
• Hori’s nevus
• Dermal melanocytosis
• Deep facial pigmentation

Hori nevus commonly appears on:

• Cheeks
• Temples
• Forehead
• Nose
• Eyelids
• Around the eyes

What Causes Hori Nevus?

Hori nevus develops when pigment-producing cells are located deeper in the dermis.

Contributing factors may include:

• Genetic tendency
• Sun exposure
• Hormonal influences
• Skin aging
• Dermal melanocyte activity
• Asian skin type predisposition

Because the pigment is deeper than many surface pigmentation conditions, treatment usually requires specialized laser therapy.

Hori Nevus vs Melasma vs Freckles

Hori Nevus

Usually appears as:

• Blue-gray or brown-gray pigmentation
• Deeper dermal pigment
• Bilateral cheek pigmentation
• Persistent discoloration

Melasma

Usually appears as:

• Brown or gray-brown patches
• Hormone-related pigmentation
• Symmetrical facial discoloration
• Recurrent pigmentation

Freckles and Sun Spots

Usually appear as:

Correct diagnosis is important because Hori nevus requires different laser settings than melasma or freckles.
