The depth is not affected by sunlight. The size ranges from a few millimeters to tens of centimeters, with clear boundaries and the surface skin texture is completely normal. The microscopic manifestation is very similar to freckles, mainly manifested as an abnormal increase in the amount of melanin in the epidermis, but the number of melanocytes is normal.

Café au lait spots are most common in patients with neurofibromatosis. About 70% of patients with neurofibromatosis have café au lait spots. If there are six café au lait spots with a diameter greater than 1.5 cm, they have important diagnostic reference value.

In addition, cafe au lait spots can also be seen in tuberous sclerosis and other neuroectodermal syndromes.

Since the melanocytes of cafe au lait spots are distributed in the epidermis, shorter wavelengths and smaller energy densities can destroy the epidermal melanocytes. 510nm pulse dye lasers and 532nm Q-switched frequency-doubled Nd:YAG lasers are both good choices.
