We report on a 61-year-old patient with massive scrotal herniation of the bladder and non-Hodgkin malignant lymphoma. We briefly describe this disease entity and its form of presentation, and discuss its diagnosis and treatment.

A case of diverticulum of the female urethra complicated by lithiasis is described. The etiopathogenic aspects, clinical features, diagnostic methods and treatment of this rare condition are discussed.
We present a case of diffuse malignant mesothelioma of the tunica vaginalis testis, a very uncommon tumor site, in a patient who also had a tumor localized to the chest. We could not determine however, whether the testicular neoplasm was a primary tumor or a distant metastasis. We describe this tumor type, its mode of presentation, diagnosis and treatment.
A case of hydatid cyst of the adrenal gland in a patient with a previous history of hydatidosis is described. Following a brief discussion of the pathological features of adrenal cysts, attention is focussed on the diagnosis and treatment of this specific form of adrenal cyst: the hydatid adrenal cyst.
A case of epidermoid carcinoma of the renal pelvis is described. The etiologic, prognostic and therapeutic aspects of this uncommon tumor of the upper urothelium are discussed.
We report on four cases of renal angiomyolipoma. Treatment was by conservative surgery in two cases, and regular control for the remaining two cases. The different diagnostic methods and therapeutic modalities are discussed.
We report a case of bilateral adrenal pheochromocytoma in a young, male patient who consulted for arterial hypertension. The adrenal tumors had been accurately diagnosed by abdominal ultrasonography and confirmed by CT. The incidence of bilateral involvement in pheochromocytoma is briefly discussed and the methods currently utilized for topographic localization of the tumor are described.

Two cases of transitional cell inverted papilloma are described. The first case was a 44-year-old male patient who presented with hematuria. The second case was an incidental finding during a retropubic adenomectomy procedure. We describe the clinical features of this condition and discuss its histogenesis and treatment. Because of the possibility, although very small, of its evolving to malignancy, these patients must be followed carefully.
Renal adenocarcinoma presenting as a cystic mass is uncommon and causes difficulty in making the differential diagnosis. Ultrasound and particularly CT are considered to be the most useful diagnostic methods. The usefulness of ultrasound or CT-guided punction-aspiration has yet to be established since the aspirate is often non-specific. The major difficulty encountered when making the differential diagnosis is that of distinguishing cystic renal adenocarcinoma from multilocular cystic nephroma. Multilocular renal carcinoma and multilocular cystic nephroma are the most common adult multilocular renal cystic masses. The latter is more common in the female, whereas cystic renal adenocarcinoma is more common in the male patient.
Lymphomas constitute a group of malignant lymphoreticular diseases that may affect the adrenal glands and the GU system as a primary condition or, more frequently, as distant invasion. We report on a case of diffuse, histiocytic non-Hodgkin lymphoma that had been in hematologic clinical remission but had recurred with invasion of the right renal parenchyma. Initially, it could not be determined whether it was a primary neoplasm or the result of primary lymphatic spread. The reports published in the literature relative to this condition are reviewed.
Three additional cases of cephalad blind-ending ureters are reported herein. These cases had been diagnosed during IVP evaluation for other disorders. Its mode of presentation and diagnosis are briefly discussed and the literature reviewed.
A case of renal angiosarcoma is presented. The extremely unusual frequency of this entity, its clinical and pathological features, and mode of presentation accompanied by intense intratumor hemorrhage, a unique finding compared to other cases of renal angiosarcoma thus far reported, have been highlighted.
