RESUMO
Presentation of one case of malignant fibrohistiocytoma derived from the renal capsule. While conducting a bibliographic review the low incidence of this tumoration of renal origin was noted. The difficulties in differentiating this entity from a secondary renal invasion by a malignant fibrohistiocytoma derived from other retroperitoneal structures is commented. Brief review of current diagnosis and therapeutical management for this tumoral entity.

An additional case of verrucous carcinoma of the penis is described. This tumor type accounts for approximately 5% of squamous carcinomas of the penis. Today penile verrucous carcinoma is widely considered to be the same tumor as that described by Buschke and Löwenstein in 1925. The histological and clinical features as well as the therapeutical aspects of this tumor type are briefly reviewed herein.

Fibroepithelial polyp of the trigone of bladder conditioning an occlusive syndrome at the bladder cervix level causing secondary multidiverticular bladder with ureterohydro-nephrosis and chronic bilateral pyelonephritis. Besides the rare vesical location for the fibroepithelial polyps, the case also presents some atypical stromal cells.

An AIDS case, with a Candida urinary infection causing papillary necrosis and accompanied by occurrence of fungal lumps is reported. The paper remarks on the incidence and peculiarities of urinary affectation in these patients, emphasizing the usefulness of percutaneous nephrostomy as a diagnostic, and above all as a therapeutic procedure, in cases of expanded urinary tract.

We present two case of inverted vesical papillomas, one of a trabecular histology and the other glandular, which--in view of the appearance in the last few years of inverted papillomas coexisting alongside other urothelium tumorous states, recurring and even malignant inverted papillomas--raise the possibility of them being considered as superficial urothelium carcinomas. We propose the use of post-surgical endo-vesical chemotherapy, above all in the patients affected by the trabecular variety of inverted papillomas, due to their high indices of recurrence and high possibilities of malignancy.

We report another case of multilocular cyst of the kidney. We underscore the current theory on the neoplastic and not cystic origin of this disease entity. Attention is drawn to the confusion arising from a wide variety of terms (17) used to refer to this disease entity. Its clinical features, diagnosis, and treatment are briefly discussed. We highlight the need to follow currently available diagnostic criteria in diagnosing multilocular cyst of the kidney.
