Halo nevus

Halo Nevus

A Halo Nevus (pronounced: /ˈheɪ.loʊ ˈniː.vəs/), also known as Sutton's Nevus or Leukoderma Acquisitum Centrifugum, is a type of melanocytic nevus that is surrounded by a depigmented ring or 'halo'. This condition is generally benign and often occurs in children and young adults.

Etymology

The term 'Halo Nevus' is derived from the Greek words 'halos', meaning 'disk' and 'nevus', meaning 'birthmark'. The term 'Sutton's Nevus' is named after the American dermatologist, Richard Lightburn Sutton, who first described the condition in 1916.

Symptoms

The primary symptom of a Halo Nevus is a mole that is surrounded by a white or light ring. This ring is caused by the loss of melanocytes, the cells responsible for skin pigmentation. The mole itself may be of any color, but is often brown or black.

Causes

The exact cause of Halo Nevus is unknown. However, it is believed to be an autoimmune response, where the body's immune system attacks the melanocytes in the skin, leading to depigmentation.

Treatment

In most cases, no treatment is necessary for a Halo Nevus as it is a benign condition. However, regular monitoring is recommended to detect any changes in the size, shape, or color of the nevus.
