Introduction: urothelial papillomas of the bladder are uncommon benign tumors predominantly occurring in male children and young adults. Objective: present a new case of urothelial papilloma of the bladder as well as aspects of its diagnosis and treatment. Clinical case: male patient aged 20 presenting at urology consultation with macroscopic hematuria of three days' evolution. Interrogation revealed that the latter was terminal, monosymptomatic and was not accompanied by clots. The physical examination was normal. Abdominal ultrasonography revealed the presence of an echogenic tumoral lesion of irregular contour projecting from the bladder bottom toward the right side. Cystoscopy confirmed the presence of the tumor described above. Transurethral resection of the lesion was performed without any complications. The anatomo-pathological report identifies the surgical piece as an urothelial papilloma. The patient's evolution has been satisfactory. In semiannual and annual checkups he has been found to be asymptomatic. Ultrasonographic and cystoscopic examination has shown no evidence of tumor recurrence. Conclusions: urothelial papillomas of the bladder rarely cause hematuria. Transurethral resection is a safe, effective treatment option. It is necessary to establish a differential histopathological diagnosis with respect to other non-invasive neoplastic urothelial lesions, given the particular recurrence features, progression and management of these tumors.
