Café au Lait Spot

Café au Lait Macule

Overview

Café au lait spots are flat, pigmented birthmarks that are the color of coffee with milk (light brown). They are caused by a higher concentration of melanin in the skin. One or two spots are very common and benign, but having six or more may be associated with neurofibromatosis or other genetic conditions.

Key Symptoms

• Well-defined, smooth borders
• Range from a few millimeters to over 20 cm
• Present at birth or appear in early childhood
• Do not darken significantly with sun exposure
• Usually oval or round in shape

Care Instructions

1. No treatment is required for isolated café au lait spots.
2. Monitor for the development of additional spots, especially in children.
3. See a dermatologist or geneticist if six or more spots are present, as this may indicate neurofibromatosis.
4. Cosmetic treatments such as laser therapy are available if desired.
5. Spots do not require sun protection beyond normal recommendations.
