Café au lait spot

Café au lait spots, or café au lait macules, are flat, hyperpigmented birthmarks.

The name café au lait is French for “coffee with milk” and refers to their light-brown color. Café au lait lesions with rough borders (“coast of Maine”) may be seen in McCune-Albright syndrome.

In contrast, Café au lait lesions of neurofibromatosis have smooth borders (“coast of California“).
