[Inverted papilloma of the bladder. Apropos of 2 cases].
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.
[Cystic renal adenocarcinoma].
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.
[Lymphoma and the urogenital system: apropos of a case].
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.
[Giant calculus in a diverticulum of the anterior urethra].
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.
[Malignant retroperitoneal fibrous histiocytoma of the inflammatory type. Apropos of a case].
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.
