A Giant Pure Uterine Lipoma: A Case Report.

Aims: The authors present a case of a giant pure lipoma of the uterus revealed by a postmenoposal metrorrhagia and discuss the clinical, radiological, histological characteristics and the different histogenesis hypothesis of this entity. Case Presentation: We report the case of a 73-year-old woman who presented with a pure uterine lipoma in which a preoperative diagnosis of ovarian teratoma was suggested by computed tomography. Conclusion: Pure uterine lipoma is extremely rare and only a few cases have been reported in the literature. It usually develops in postmenoposal women. Clinical symptoms and physical signs are similar to those found in leiomyomas. Nevertheless, preoperative diagnosis is difficult and requires pathological confirmation.

A Rare Highly Aggressive Tumor of the Kidney: The Pure Epithelioid Angiomyolipoma.

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.

Urinary Bladder Cavernous Hemangioma: A Case Report.

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.
