Neurofibromatosis type 1 (NF1) is an autosomal dominant disease with multiple neurofibroma and caféau- lait spots. We report a case of plexiform neurofibroma of the bladder associated with NF1. A 34-yearold female was referred to our hospital for thickness of the bladder wall. Multiple café-au-lait spots and neurofibroma was found on her skin,and she was diagnosed with neurofibromatosis type 1. Ultrasound examination demonstrated bladder wall thickening,and cystoscopy revealed an irregular and erythematous mucosa. Transurethral biopsy of the bladder wall was performed. Histopathological diagnosis was plexiform neurofibroma of the bladder.
