Background

Café au lait spots, or café au lait (CAL) macules (CALMs), are hyperpigmented lesions that may vary in color from light brown to dark brown;[1] this is reflected by the name of the condition, which means "coffee with milk." The borders may be smooth or irregular.

The size and number of café au lait skin lesions widely vary and are usually the earliest manifestations of neurofibromatosis.[2] The macules may be observed in infancy, although they are typically very light in infants and can be difficult to appreciate. The skin lesions develop in early infancy, and they may enlarge in size and become obvious after age 2 years.

Café au lait macules are observed in 95% of patients with neurofibromatosis type 1 (NF1), which is the most frequently occurring neurocutaneous syndrome. These spots may also be observed in patients without NF1. Other conditions in which they may be observed include McCune-Albright syndrome, tuberous sclerosis, and Fanconi anemia.

Pathophysiology

Café au lait spots are caused by an increase in melanin content, often with the presence of giant melanosomes. A significant increase in melanocyte density is noted in the café au lait macules of patients with NF1 compared with patients who have isolated café au lait macules without NF1 involvement. Also, an increase in stem cell factor cytokines is more frequently observed in NF1 café au lait macules than non-NF1 café au lait macules.

Epidemiology

Frequency

United States

In the newborn period, solitary café au lait spots may occur in 0.3% of whites, 3% of Hispanics, and in 18% of blacks.[3] In childhood, solitary café au lait macules occur in 13% of whites and 27% of blacks. Two or more café au lait macules were not observed in any of 4000 white newborns, although they were found in 8% of black newborns. Café au lait spots that confirm the diagnosis of NF1 occur at an estimated frequency of 1 in 3500 persons.[4]

International

Solitary café au lait spots occur in 0.5% of Arab newborns and in 0.4% of Chinese newborns.[3]

Race

Café au lait spots are more frequently observed in black children.

Sex

No sexual predilection is recognized.

Age

Typically, café au lait spots are present at birth, although they may be difficult to appreciate. A Wood lamp may improve the ability to visualize these faint spots. By the time the child is aged 2-3 years, café au lait macules are clearly visible. The size and number of café au lait macules increase with patient age in patients with NF1.
