Naevus of Ota
If you have a patch of skin with a bluish-grey or medium brown colouration, you may have a condition called "Naevus of Ota" named after the physician who first identified this skin abnormality. At Scars & Lasers, our board-certified dermatologists provide treatment for Naevus of Ota.
What is Naevus of Ota?
Nevus of Ota is a benign skin condition characterised by bluish-grey or brown patches, typically appearing on one side of the face around the eyes, forehead, and cheeks. It is caused by increased pigment-producing cells (melanocytes) in the dermis and is more common in individuals with darker skin tones. Having a Naevus of Ota, while medically harmless, can be a significant source of emotional distress for individuals due to its noticeable appearance.
The Science Behind It
The exact cause of Naevus of Ota is still unknown, though it is thought to be linked to abnormalities in melanin-producing cells. Approximately half of the cases are present at birth, which is why it is classified as a birthmark. However, Naevus of Ota can also develop during adolescence or early adulthood.
Naevus of Ota results from an accumulation of melanocytes within the dermis, the deeper layer of the skin. These cells overproduce melanin, the pigment responsible for skin colour, leading to the characteristic bluish appearance due to the Tyndall effect, where light scatters through the dermal layers. Treatment targets these deep melanocytes using laser therapy, which breaks down excess pigment without damaging surrounding tissues. While multiple sessions are often required to achieve the desired results, these treatments can greatly reduce the visibility of the nevus, providing emotional relief and enhancing quality of life for those affected.
