A 62-year-old man presented with right-sided abdominal pain. Radiologic examinations disclosed a solid tumor in the ileocecal mesentery that obstructed the right ureter, thus resulting in urinary extravasation. An en bloc tumor resection with the ascending colon, the terminal ileum, and a portion of the right ureter was performed. Histopathologically, the tumor was adenocarcinoma with extensive neuroendocrine differentiation which had arisen in an ileal diverticulum. The patient developed metastases to the lymph nodes, liver, and brain, and died 18 months after surgery.

Synovial metastases from neoplasms are uncommon. We report two cases of knee monoarthritis due to joint metastasis. Joint fluid cytology established the diagnosis. In one patient, an epidermoid carcinoma of the ureter metastasized to the left knee. The other patient had chronic monoarthritis of the left knee unresponsive to conventional treatment and was found to have distal femoral metastases from a lung adenocarcinoma. Only 28 cases of synovial metastases from solid tumors have been reported in the literature. The knee is the most common target, the lung the most common site of the primary (12 cases), and adenocarcinoma the most common histological type (12 cases). Joint metastasis carries a poor prognosis with a mean survival of less than 5 months.

Advances in endourology have made transluminal balloon dilatation a safe and effective procedure for the treatment of ureteral strictures. Bilateral ureteral stricture was treated with retrograde balloon dilatation and ureteral stenting in a 59-year-old-woman. The patient had previously undergone abdominoperineal resection and adjuvant radiotherapy due to rectosigmoid adenocarcinoma. Subsequently, unilateral ureteroenteric fistula was detected on follow-up retrograde ureteropyelography. To our knowledge, this is the first case of ureteroenteric fistula after balloon dilatation for ureteral stricture in a patient with predisposing factors for compromised vascularity of the ureter.

The malignant tumors of the inferior vena cava are rare. Their prognosis is bad. We report two cases of a 17-year-old and 46-year-old woman presenting the one an intimal sarcoma of the inferior vena cava and the other a metastatic of adenocarcinoma whose primary tumor was not identified. The aortic wall was invaded in both patients. The ureter repulsed in first case, was invaded in second case. The treatment consisted on resection of the tumor including the aortic wall with vein closure in both patients, with right nephrectomy in second patient. In the two cases, a prosthetic reconstruction of the arterial integrity was attempted with aortobiiliac bypass. The two patients died after relapse tumorous to the 6th month in first patient and by multisystem organ failure 5th day post-operative in second. Through these two personal cases, we try to point out the difficult problem of diagnosis that put these tumors and their bad prognosis despite an improvement of treatment.

We are presenting a 68-year-old female patient who was diagnosed to have a complete ureteral duplication and adenocarcinoma in the ureter which drained the upper moiety of the right kidney.

Primary ureteral adenocarcinoma is an infrequent histological type of urinary neoplasm. Many authors consider intestinal metaplasia the pivotal event of the pathogenetic process, whether it occurs on a pre-existing urothelial carcinoma or on a normal urothelium. Diagnosis is essentially based on case history and clinical findings (hematuria and pain) and on diagnostic imaging. Treatment is surgical and the ideal procedure is nephroureterectomy with excision of a bladder margin adjacent to the ureteral opening and ispilateral para-aortoiliac lymphadenectomy. A 76-year-old man with primary adenocarcinoma of the ureter case is reported.

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.

We report a case of advanced renal pelvis and ureter adenocarcinoma producing carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125). A 72-year-old woman was diagnosed with right renal pelvic and ureter tumor with para-aortic lymph node swelling. Biopsy of the ureteral mass revealed papillary adenocarcinoma. Serum levels of CEA, CA19-9 and CA125 were extremely elevated. The patient was successfully treated with paclitaxel/carboplatin chemotherapy followed by surgery.

Virtual colonoscopy provides a computer-simulated endoluminal perspective of the air-filled, distended colon using modern CT scanning (spiral CT). According to recent studies the sensitivity and specificity of this technique are high for adenomatous polyps > or = 10 mm. A 67-year-old patient was admitted to our hospital because of diarrhoea and constipation, associated with abdominal pain in the lower right abdomen. Prior to admission the patient had undergone virtual colonoscopy in a specialised radiological practice which had detected no abnormalities apart from colonic diverticulosis. However, conventional video-colonoscopy revealed a subtotal circular malignant stenosis in the region of the right colonic flexure. A poorly differentiated adenocarcinoma was diagnosed histologically. Staging showed peritoneal carcinosis with infiltration of the right ureter and lymphangiosis carcinomatosa of the pectoral lobe of the left lung. After right hemicolectomy because of metastasised carcinoma of the ascending colon (pT4pN1pM1) we started palliative chemotherapy with oxaliplatin, 5-fluorouracil and leucovorin. The risk of misdiagnosis by virtual colonoscopy is clearly increased in patients with subtotal tumour stenosis of the ascending colon. Conventional video-colonoscopy remains the gold standard for the diagnosis of colorectal carcinoma.

We present a unique case of urothelial carcinoma of the right renal pelvis. It occurred in a 58-year-old woman. The tumor was located in the renal pelvis with extension into the adjacent renal medulla and cortex. Two years after surgical excision the patient is free of recurrence and metastasis. The tumor was well demarcated, without capsule, firm, solid, and whitish on the cut surface. It was 3x4 cm in largest diameter and without signs of necroses and hemorrhages. The tumor did not infiltrate the ureter. Histologically the predominant pattern of the tumor was adenocarcinomatous differentiation, and only very rare foci of urothelial carcinoma composed of typical transitional cells were found. No signs of intestinal type of metaplasia and adenocarcinoma, changes similar to the cystitis cystica or cystitis glandularis, were found in the tumor or in its vicinity. Most of the tumor looked like solid nests composed of cells with intracytoplasmic lumens. The resulting appearance was that of typical signet-ring cell change. These solid nests were usually surrounded by columnar epithelium, which in many areas formed papillary structures. A very striking feature was formation of collagen spherules. Small collagen spherules were often surrounded by a layer of the neoplastic cells so that collagenous rosettes were formed. In some areas these collagenous spherules clustered together so that they formed areas of collagenous spherulosis. The collagen in the spherules reacted positively with collagen IV. Ultrastructurally these spherules were formed by basal membrane-like material. Intracytoplasmic lumens of the signet-ring cell change were endowed by slender microvilli at ultrastructural level.
