Coffee spots, also known as coffee-milk spots, are brown patches that can be found at birth, ranging in color from light brown to dark brown, with each patch having the same color and very uniform, and the color shades are not affected by sunlight. Coffee spots can be a single manifestation or a sign of a systemic disease, such as neurofibromatosis. It is believed that the presence of neurofibromatosis is highly suspected if there are six coffee spots with a diameter greater than 1.5 square centimeters. Coffee spots can be treated with Q-modulated laser with ideal results.
