Report on two new cases of Bellini's collector duct carcinoma (CTC), discussing the clinical, radiological and pathological aspects which differentiate this disorder from the clear cells carcinoma, and review of the related literature.

We report a case of carcinosarcoma whose most striking feature was its markedly chondroid elements that initially prompted us to suspect a chondrosarcoma. The clinical features and treatment of this rare tumor type are briefly discussed.
We report on a 50-year-old male patient with acquired urethral diverticulum complicated by calculus in the anterior urethra. The etiologic factors, the hypotheses put forward relative to the pathogenesis of urethral diverticulum, its diagnosis and forms of treatment are discussed.
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.
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.
Two cases of unilateral ureteral diverticulum are reported, one of which was associated with a bifid ureter. In the first case, this anomaly was incidentally discovered during a urographic work up of a patient with colic nephritis. In the second case, the presenting symptom was hematuria which was finally attributed to ureteral diverticulosis. A structural classification of these anomalous lesions is described, and the commonly associated conditions (obstruction, infection) are reviewed. The authors do not advocate treating these anomalies.

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.
A case of lithiasis in a front diverticulum of the urethra in male is presented. The unusual presentation it had together with the lack of frequency was pointed out, commenting briefly the diagnostic methods and ways of treatment.
A case of inflammatory malignant fibrous histiocytoma is described herein. We discuss its clinical features, therapeutic possibilities and diagnosis, highlighting the usefulness of magnetic resonance imaging as well as the importance of correct anatomopathological diagnosis.
