YooSY, HwangSM, Lee MK, Jo DS, Hwang PH. Simultaneous presentation of malignant peripheral nerve sheath tumor and moyamoya disease associated with neurofibromatosis type 1 in a child. Turk J Pediatr 2015; 57: 202-205. Neurofibromatosis type 1 (NF-1) is a rare hereditary disorder, which is inherited as an autosomal dominant trait. It is characterized by multiple caféau-lait spots of the skin, benign cutaneous neurofibromas, skeletal dysplasia and learning disability. The association of NF-1 with benign and malignant tumors is well established. The lifetime risk of patients with NF-1 developing malignant peripheral nerve sheath tumors (MPNSTs) has been estimated to be 8-13%. Such tumors can develop in any part of the body, but their occurrence in the gastrointestinal tract is rare. Patients with NF-1 have a wide spectrum of vascular abnormalities. Cerebrovascular lesions have been found in approximately 2.5% of children with NF1. We encountered a case of NF-1 with MPNSTs in the gastrointestinal tract and moyamoya disease.
