Bladder paraganglioma treated with open partial cystectomy: a case report

Background: Bladder paraganglioma is a neuroendocrine tumor that accounts for less than 0.1% of all bladder tumors. Symptoms caused by catecholamine release such as hypertension, palpitation, syncope, and macroscopic hematuria are the most common findings. Treatment modalities include transurethral resection, and partial or total cystectomy. Case presentation: A 38-year-old Turkish female patient was examined for hematuria that had been persisting for 6 months. Among the clinical findings, only hematuria was present. Absence of adrenergic symptoms such as hypertension, palpitations, and syncope at the first presentation made it difficult to consider bladder paraganglioma in the differential diagnosis. Therefore, cystoscopy and transurethral resection were performed with the thought of urothelial cancer. Findings such as hypertension and bradycardia that developed during diagnostic transurethral resection suggested that it might be bladder paraganglioma. After the radiological evaluation and endocrinological preparation, the patient underwent partial cystectomy. Conclusion: The rarity of cases having been reported in the literature leads to uncertainties in the management of bladder paraganglioma. Adrenergic symptoms developing during transurethral resection should suggest paraganglioma in the differential diagnosis. A multidisciplinary approach and medical treatment are mandatory to prevent life-threatening complications such as hypertensive crisis, vascular collapse, and multiple-organ system failure. We aimed to report the clinical presentation that includes only macroscopic hematuria mimicking urothelial cancer and to emphasize the multidisciplinary approach in the treatment.
