Giant Mesenteric Angioleiomyoma: A Rare Case Report

Area of Science:

• Oncology
• Pathology
• Urology

Background:

• Angioleiomyomas are rare, benign smooth muscle neoplasms originating from blood vessels.
• These tumors exhibit characteristic histology but nonspecific clinical presentation, complicating diagnosis.
• Location near the urinary bladder is exceptionally uncommon.

Purpose of the Study:

• To report a case of a large angioleiomyoma near the urinary bladder.
• To describe the clinical course, diagnostic challenges, and management of this rare entity.
• To contribute to the understanding of angioleiomyomas in unusual anatomical sites.

Main Methods:

• Case report of a 23-year-old male with abdominal pain.
• Diagnostic workup included ultrasonography and histopathological examination.
• Surgical management involved an external approach for tumor resection.

Main Results:

• A large (30 cm × 20 cm) angioleiomyoma was identified originating from the urinary bladder fundus.
• Histopathology confirmed a benign spindle cell neoplasm consistent with angioleiomyoma.
• The large size necessitated an external surgical approach for complete resection.

Conclusions:

• Angioleiomyomas, though rare, can present as large masses in unusual locations like the urinary bladder.
• Diagnosis relies on histopathological and immunohistochemical analysis due to nonspecific initial findings.
• Further research is needed to elucidate the etiology and optimal treatment strategies for angioleiomyomas at this site.
