ABSTRACT
Aims: The authors presents a case of pure Renal epithelioid angiomyolipoma (EAML) and discuss the clinicopathological characteristics and the diagnosis problems of this entity. Case Presentation: A 51 year-old man presented with a persistant pain in the left lumbar region. Imaging revealed a left kidney tumor that was hemorrhagic and necrotic on gross examination. At histology, proliferation of 99% of atypical epithelioid cells, staining for HMB-45 and Melan A was observed. Our patient had lung and right adrenal metastasis six months after surgery and succumbed one year later. Conclusion: In summary, the pure form of EAML is extremely rare. When diagnosed, the risk of tumor progression is high, especially if other histological predictive parameters of progression are observed. In that case, active treatment should be undergone and patients should be closely monitored.
ABSTRACT
Aims: The authors present a case of urinary bladder cavernous hemangioma and discuss the clinical and pathological features of this entity. Case Presentation: We report a solitary bladder cavernous hemangioma occuring in a 19-year-old man. The patient presented with macroscopic hematuria. Radiologic findings revealed an intravesical exophytic tumor. Cystoscopy revealed a sessile, reddish mass, measuring 2 cm in diameter located in the right sided wall of the bladder. Endoscopic resection of the mass was performed and the pathologic examination revealed a cavernous hemangioma. No recurrence was noted at the 3-year follow-up. Conclusion: Hemangioma is a benign vascular tumor accounting for about 0.6% of bladder tumors. Its prognosis is generally good but a long follow-up observance is mandatory to detect recurrence or residual disease.
