ABSTRACT
Neurofibromatosis type 1 (NF-1) is the most common neurocutaneous syndrome. It is inherited in an autosomal dominant manner, with many patients having the syndrome as the result of a de novo mutation. NF-1 is caused by a mutation in the NF-1 gene located on the chromosome 17q11.2. NF-1 gene mutations result in the absence or reduced function of neurofibromin protein, thereby promoting tumor development and other clinical findings. NF-1 is fully penetrant, and it is commonly manifested by café-au-lait macules, axillary and/or inguinal freckling, neurofibromas, and Lisch nodules in the eyes. Skeletal manifestations include scoliosis, short stature, long bone dysplasia, and pseudoarthrosis. Rarely, NF-1 can manifest lambdoid suture defects. This report describes the case of a 12-year-old neurofibromatosis patient who presented to the pediatric clinic with a palpable posterior scalp defect, as well as café-au-lait macules and Lisch nodules. Diagnosis of NF-1 was made clinically. MRI and CT scan were done, and the patient was diagnosed with a lambdoid suture defect that is not associated with plexiform neurofibroma. Moreover, whole exome sequence (WES) was done, and diagnosis of NF-1 was confirmed. Watchful waiting and continuous monitoring were the management of choice for this case.
