A Case of Isolated Neurofibroma of the Bladder in A Young Adult Man with No History of Neurofibromatosis Type 1: A Case Report

Abstract

Background and Objective: Genitourinary neurofibroma is a benign nerve sheath tumor commonly found in patients with neurofibromatosis type 1. This disease is very rare and can appear in all urinary tracts. Considering the rarity of neurofibromatosis of the bladder, the present case report is introduced with the aim of showing the importance of this pathology. Case Report: The patient is a 25-year-old man who visited the urology clinic last month due to hematuria. The patient did not mention any other clinical symptoms. An ultrasound was requested for the patient, and a mass was reported in the bladder. The patient underwent mass resection through the urethra. In the pathological and immunohistochemical studies, the patient was diagnosed with neurofibromatosis. The general condition of the patient after surgery is good and the patient's symptoms are resolved. Conclusion: According to the results of this study, the patient was symptomatic and had a mass in the bladder on ultrasound. Due to the lack of a previous diagnosis of neurofibromatosis type 1 for the patient and the lack of a definite diagnosis about the type of mass, the best treatment approach is surgery and complete removal of the mass. After the final diagnosis based on histopathological and immunohistochemical evaluations, the best approach is to follow up the patient with imaging.
