A Case of Partial Unilateral Lentiginosis with Cafe-au-lait Macules / 대한피부과학회지

ABSTRACT

Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder that's characterized by multiple lentigines in a unilateral distribution. The lesions often have a segmental pattern with a sharp demarcation at the midline. This is sometimes combined with other disorders such as neurofibromatosis or cafe-au-lait macules (CALMs). The presence of multiple CALMs in the same distribution as the lentigines on a PUL patient makes it difficult to differentiate PUL from segmental neurofibromatosis. We present here a 25-year-old woman with an unusual combination of several caf?-au-lait macules and scattered numerous lentigines involving the left side of the abdomen, flank and back.
