An 8-month-old Caucasian infant with neurofibromatosis type 1 presented with a congenital plexiform neurofibroma and multiple café au lait spots. A pale area surrounded one of the café au lait spots located on the left gluteus in the area of dermal melanocytosis. This halolike phenomenon results from the disappearance of the Mongolian spot around the café au lait spots, revealing normal pigmented skin. This sign has been described rarely in the literature and the pathogenic mechanism is unclear.

Abstract
An 8-month-old Caucasian infant with neurofibromatosis type 1 presented with a congenital plexiform neurofibroma and multiple café au lait spots. A pale area surrounded one of the café au lait spots located on the left gluteus in the area of dermal melanocytosis. This halolike phenomenon results from the disappearance of the Mongolian spot around the café au lait spots, revealing normal pigmented skin. This sign has been described rarely in the literature and the pathogenic mechanism is unclear.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
