Summary
Angiomyolipoma of the bladder is an extremely rare bladder neoplasm. This case report details a 55-year-old woman diagnosed with this rare tumor.
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Angiomyolipoma is a rare mesenchymal neoplasm.
- Bladder neoplasms are uncommon, with benign tumors being even rarer.
Observation:
- A 55-year-old woman presented with a 5 mm bladder polyp.
- Pelvic sonogram revealed a polypoid lesion in the bladder floor.
Findings:
- Histopathological examination showed spindle cells, epithelioid cells, and adipocytes.
- Immunohistochemical staining was positive for HMB-45, actin, and HHF-35, confirming angiomyolipoma.
Implications:
- This case highlights the importance of considering rare diagnoses in bladder pathology.
- Further research into the pathogenesis of bladder angiomyolipoma is warranted.
