BACKGROUND: Ureteral granulation tissue hemangiomas are rare benign vascular lesions, and they may be clinically asymptomatic or present with massive or recurrent hematuria. Sometimes hemangiomas are difficult to distinguish from malignant ureteral tumors, and most ureteral hemangiomas are confirmed by postoperative pathological examination. This article aims to present a case of granulation tissue-type hemangioma of the ureter and briefly review the current literature on this condition.
CASE PRESENTATION: A 30-year-old male patient presented with complaints of painless macroscopic hematuria for 2 months. Computerized tomography of the urinary system showed that the upper 1/3 of the right ureter was occupied, and then the possibility of tumor lesions was considered. The urine cytology showed occasional nuclear abnormalities and many light-stained crystals in urine. Because of suspicious radiological and cytological findings, the patient underwent the right ureteroscopy and the laparoscopic right ureteral mass resection. The postoperative pathological report showed that it was a mesenchymal tumor. The morphological and immunohistochemical staining was consistent with that of hemangioma, tending to granulation tissue hemangioma. After surgery, the patient was in a good state and recovered well at the last follow-up.
CONCLUSIONS: Ureteral granulation tissue hemangiomas are an easily misdiagnosed disease. Intermittent painless hematuria is an important characteristic of this disease. Therefore, we suggest that unnecessary radical surgery can be avoided when clinicians consider the possibility of benign ureteral tumors during the evaluation.
