[Ureteral endometriosis. Case report].

OBJECTIVES: Ureteral endometriosis is a rare entity which may produce urinary tract obstruction with subsequent loss of renal function if treatment is not undertaken early due to its asymptomatic but locally aggressive course. METHODS/RESULTS: We report one case of intrinsic ureteral endometriosis with unilateral renal failure (renal atrophy) and unresectable periureteral fibroinflammatory thickening involving vascular or visceral structures. CONCLUSIONS: We emphasize the diagnostic and therapeutic importance of a high degree of clinical suspicion about this entity, mainly in patients with history of genital endometriosis.

[Renal pelvis mucinous carcinoma. Case report].

OBJECTIVE: There is some controversy in the terminology used for transitional cell tumors with mucinous differentiation. METHODS: We report the case of a 50-year-old male with history of recurrent lithiasis whose radological tests discovered a heterogeneous renal pelvis lesion. RESULTS: The histologic study of the lesions determined the diagnosis of transitional cell carcinoma of the renal pelvis with ample mucinous differentiation. CONCLUSIONS: They are rare tumors in such location and the mucinous differentiation does not seem to influence prognosis.

[Predominantly cystic renal metanephric adenoma. Case report].

OBJECTIVES: Metanephric adenoma is a relatively unfrequent asymptomatic embryogenic renal tumor which is generally diagnosed by an abdominal diagnostic tests indicated for other reasons. Differential diagnosis with benign and malignant tumors has to be performed. METHODS/RESULTS: We report one case of metanephric adenoma with intense necrotic-hemorrhagic and cystic changes with a size not previously referred in the literature. CONCLUSIONS: Cystic and hemorrhagic changes in benign renal tumors make differential diagnosis with malignant tumors mandatory Surgery is necessary in almost all cases and histologic study will give the diagnosis.

[Sarcomatoid renal carcinoma with malignant heterologous elements: case report].

OBJECTIVE: The sarcomatoid pattern represents the histological type of renal carcinoma with the poorest prognosis, receiving the grade 4 of the Furhman classification consistently. METHODS: We report the case of a 80-year-old male who underwent nephroureterectomy with the pathologic diagnosis of sarcomatoid renal carcinoma with areas of chondro and osteosarcoma, as well as squamous cell differentiation. It is an exceptional case because it is rare to find all these elements in the same tumor. RESULTS: The study of the surgical specimen enables in most cases the identification of some of the classic histological patterns of renal carcinoma, nevertheless an immunohistochemical study is of great value for proper classification of the neoplasia and differential diagnosis with other renal lesions, mainly sarcomas. CONCLUSIONS: The presence of malignant heterologous elements, as in our case, will confirm the prognosis of these neoplasias, which really don't have an effective treatment.
