L81.3 | Café-au-lait spots |
ICD-10 online (WHO version 2019) |
Café-au-lait spots (from French café au lait = " milk coffee ") are light brown, even skin spots of different sizes that can appear in different numbers on the whole body. Since it is a sharply demarcated, benign skin lesion ( nevus ), the term nevus pigmentosus is sometimes used, but this should not be confused with the general term pigment nevus for pigmented nevi .
Appearance
Café-au-lait stains have a light to dark brown, absolutely even pigmentation. Their size can vary widely, from under 2 mm to over 20 cm. They typically appear on the extremities or trunk. In contrast to other pigment nevi, they are never raised or knotty and are not associated with hypertrichosis .
meaning
Café-au-lait stains are not a disease. 10–20% of the normal population have one or more of these homogeneous hyperpigmentations . An increased occurrence is described in vitamin B 12 deficiency , neurofibromatosis ( Recklinghausen's disease ), Fanconi anemia and McCune-Albright syndrome . If more than six café-au-lait spots with a diameter greater than 15 mm in adulthood or greater than 5 mm in children and adolescents, and the appearance of further symptoms, the diagnosis of neurofibromatosis type 1 is likely. These café-au-lait spots are typically smooth ( Coast of California ), while in McCune-Albright syndrome they appear irregularly bordered ( Coast of Maine or Coast of Massachusetts ).
