Bladder cavernous hemangioma after pelvic radiotherapy in a female patient: A case report and literature review

Haemangiomas in the urinary bladder: Two case reports

BACKGROUND

Urinary bladder haemangioma is a benign nonurothelial tumour that rarely occurs in paediatric and adolescent patients. Clinical and radiological examinations are not adequate for an accurate diagnosis. The purpose of this serial case report is to raise awareness of urinary bladder haemangioma and appropriate management.

CASE SUMMARY

We described two rare cases of urinary bladder haemangioma that were confirmed by histopathology followed by immunohistochemistry and reviewed the literature on the diagnosis and treatment of patients with this disease. The radical cystectomy was performed with open method surgery associated with an abdominal wall ostomy of the ileal outlet tract for case 1. Case 2 underwent a laparoscopic partial cystectomy. Postoperative pathology confirmed the diagnosis of urinary bladder haemangioma. Haematuria resolved postoperatively, and there was no evidence of tumour recurrence in 3 years follow-up for case 1. Postoperative urinary and pelvic ultrasonography showed no signs of recurrence in 3 mo follow-up for case 2.

CONCLUSION

Careful histopathological and immunohistochemical studies are required to establish the correct diagnosis. There is no “gold standard” treatment for urinary bladder haemangioma, and treatment options are varied for individuals with favourable follow-ups.

Transurethral resection of a large bladder hemangioma of mixed histological composition: a case report

Hemangioma is a rare benign vascular tumor of the bladder, which occurs mainly in children. It has no specific clinical symptoms but can result in severe and fatal complications as well as relapse. In the current clinical observation, a 35-year-old patient had a large solid tumor of the bladder spreading into the muscular layer. In histological and immunohistochemical analyses, verified hemangioma consisted of capillary, cavernous and arterio-venous components. The patient underwent transurethral resection of the bladder using computer chromoendoscopy. It is the first to the best of our knowledge complete transurethral removal of 3 cm in diameter bladder hemangioma.
