ABSTRACT
A case of Bellini duct carcinoma is reported. A 70-year-old man visited our hospital because of gross hematuria and left flank pain. Although no abnormality was found on ultrasonography, drip infusion pyecography, computed tomographic scan and cystoscopy. However class IV was suspected based on urinary cytology. Magnetic resonance imaging showed an irregular pattern in the left upper kidney. Ureterscopic biopsy revealed transitional cell carcinoma and class V was suspected on the urinary cytology of the left renal pelvis. Under the preoperative diagnosis of a left renal pelvic tumor, left nephroureterectomy was performed. The histopathological diagnosis with immunohistostaining was Bellini duct carcinoma. No evidence of recurrence or metastasis was noted 9 months after surgery without any adjuvant therapy.

We report two cases of retroperitoneal liposarcoma arisen from the perirenal fat tissue, which could not be diagnosed preoperatively. Case 1 is a 58-year-old male. He complained of left flank tumor. Computed tomography and magnetic resonance image showed a mass over 10 cm that contained fat components in the retroperitoneal space. The tumor was resected with left nephrectomy and histological examination revealed well differentiated liposarcoma. As adjuvant therapy, he received chemotherapy and 30 months has passed uneventfully. Case 2 is a 70-year-old male. Screening ultrasonography revealed incidental retroperitoneal tumor. With clinical diagnosis as non-functioning adrenal tumor, he received left nephrectomy. The pathological diagnosis was well differentiated liposarcoma, sclerosing type. No adjuvant therapy was performed. He has stopped visiting our clinic due to aggravation of heart disease. The characteristics of the images of the two cases were different despite the histological resemblance. This difference was considered to be due to the difference in the distribution of lipomatous tissue in each patient.

A 66-year-old man was admitted to our hospital with left flank pain. Drip infusion pyelography (DIP) and abdominal computed tomography (CT) showed urinary extravasation. Magnetic resonance imaging (MRI) and retrograde pyelography (RP) demonstrated stenosis of the ureter. Left nephroureterectomy was performed. Histopathological examination showed poorly differentiated adenocarcinoma, located in the ureteral wall with intact mucosa and adventitia. After the operation, sigmiod colon carcinoma was pointed out by colon fiberscope, and sigmoidectomy was performed.
