We report a giant renal adenocarcinoma (5150 g weight) excised in a 52 years old male. He presented a severe clinical symptoms: serious haematuria, fever (40 degrees C), left flank pain, abdominal discomfort and weight loss (10 kg). The patient underwent left renal artery embolization because of severe anemia (blood transfusion: 4 uu) but haematuria didn't decrease; that's why radical surgery was advised. Until our knowledge this case is the largest removed kidney adenocarcinoma published in the world literature (Medline 1966-2001).

The differential diagnosis of acute flank pain includes kidney stones, urinary tract infection, dissecting abdominal aortic aneurysm (AAA), arterial or venous compromise of the kidney, renal abscess, renal carcinoma, and papillary necrosis. This is a report of an unusual cause of renal colic: pyelocalyceal diverticulum. Stasis of urine within a diverticulum promotes both calculus formation and urinary tract infection, either of which can lead to colic. Several radiographic findings may suggest a calyceal diverticulum, including, on plain X-ray, a very peripheral or mobile renal calculus, or on intravenous pyelogram, an early filling-defect and delayed or retained filing of a circular or ovoid mass.

A 34-year-old female with left flank pain persisting for 3 months consulted us on 19 Feb, 2001. Ultrasonography (US), computerized tomography (CT), magnetic resonance imaging (MRI) and renal angiography revealed a cystic renal tumor in the upper pole of the left kidney invading the spleen, and paraaortic lymph node swelling. Left radical nephrectomy combined with splenectomy and partial diaphragmectomy was performed under a tentative diagnosis of renal cell carcinoma. However, histopathological findings revealed xanthogranulomatous pyelonephritis (XGP). XGP is a rare, severe, chronic inflammatory disease characterized by accumulation of lipid laden macrophages. XGP is classified as diffuse or focal type. Preoperative diagnosis of focal XGP is difficult because of radiological similarities to renal cell carcinoma. Our case was more difficult to diagnose because she showed few signs of inflammation and had no history of urinary tract infection or stones.

In renal tumors, we often encounter cases in which accurate diagnosis before surgery is difficult. The serial changes in various diagnostic images were studied in a case of renal cell carcinoma in which definitive diagnosis could not be made by various imaging examinations and biopsies. We report on a case of renal cell carcinoma in a young adult. A 19-year old man complained of left flank pain and pyrexia. Computerized tomography (CT) scan and urography revealed a solid mass in the left kidney. Angiography revealed no abnormality, and CT scan after 3 months showed that the mass was decreasing in size, which suggested an inflammatory mass. CT scan and retorograde pyelography 12 months later showed that the tumor had enlarged and that much of the tumor had extended into the renal pelvis. Left nephrectomy was performed and histological examination revealed that the tumor was papillary renal cell carcinoma. When imaging results and clinical symptoms are atypical, pre-surgery diagnosis of renal cell carcinoma is extremely difficult. In such cases, we found that it was effective to observe the changes in various diagnostic images and to make an overall judgment based on these results.

A 56-year-old woman was admitted with right flank pain as the chief complaint without any trauma. Abdominal and chest computed tomography (CT scan) demonstrated with low-density area in a retroperitoneal hematoma suspected of spontaneous rupture of angiomyolipoma and hematothorax. Superselective transarterial embolization and drainage of the thoracic cavity were performed. Three months later a right renal tumor in perirenal hematoma was revealed by abdominal CT scan and suspected renal cell carcinoma. Right nephrectomy was performed. Histopathology revealed renal cell carcinoma. Including this case, 31 cases of spontaneous rupture of renal cell carcinoma have been reported in the Japanese literature.

We report a case of bilateral synchronous renal cell carcinoma in a 66-year-old-man, who underwent bilateral partial nephrectomy. He visited our hospital, complaining of left flank pain. Drip infusion pyelography showed a left ureteral stone and left hydroureteronephrosis. Computerized tomography revealed bilateral renal tumors. These tumors were small (< 2 cm), so bilateral partial nephrectomy and left ureterolithotomy were performed. The pathological examination showed that all tumors were renal cell carcinoma. No recurrence has been seen nine months after the operation. This is the 12th case in the Japanese literature reported as bilateral partial nephrectomy for bilateral synchronous renal cell carcinoma.

A 67-year-old male had been maintained on hemodialysis for 13 years because of chronic renal failure secondary to diabetes mellitus. The patient was referred to our hospital with sudden right flank pain. Computed tomography revealed multiple cysts in both kidneys and a right massive perirenal hematoma. Although there was no definite evidence of a renal tumor, a right nephretomy was performed. Histological study revealed acquired cystic disease of the kidney (ACDK) with a hematoma containing papillary renal cell carcinoma. He has been free of recurrence for 2 months. To our knowledge, this case is the fourth report of renal cell carcinoma in ACDK manifested by spontaneous rupture in the Japanese literature.

Little information is available concerning the morbidity of radiofrequency ablation (RFA) or the evolution of an RFA lesion over time. We report our findings in a kidney removed 1 year after RFA of a 2.3-cm renal tumor. After RFA, the patient experienced flank pain, followed by hydronephrosis, ureteropelvic junction obstruction, and eventual loss of function in the treated kidney. Nephrectomy revealed no residual renal cell carcinoma. RFA can completely destroy renal cell carcinoma in situ without histologic evidence of persistence or recurrence for up to 1 year after treatment. Care must be taken to avoid concurrent damage to the collecting system.

A 70-year-old male presented with left flank pain and history of gross, total painless haematuria of 6 months duration. Investigations revealed a large solid and cystic mass suggestive of renal cell carcinoma in left kidney with possible infiltration of left psoas muscle. Histology of radical nephrectomy showed angiomyolipoma with multiple cysts lined by columnar epithelium suggestive of tuberous sclerosis and focal area of xanthogranulomatous pyelonepheritis. The rare combination of such lesions leading to diagnostic dilemma has not been reported in medical literature to the best of our knowledge.

Renal cell carcinoma was diagnosed in three male patients, 45, 53 and 52 years of age. In addition, they had paraneoplastic symptoms: hypercalcaemia, hyperglycaemia and elevated hepatic enzyme levels, respectively. All three patients underwent tumour nephrectomy, after which the paraneoplastic symptoms disappeared. The first patient died 16 months postoperatively, while the other two were alive and free of symptoms after a follow-up of nine months and four years, respectively. Many patients with renal cell carcinoma remain asymptomatic for a long period of time and 30% of all patients have metastatic disease at the time of diagnosis. The classic triad of flank pain, haematuria and an abdominal mass occurs in only 10% of all cases. However, 20-40% of all patients present with signs of a paraneoplastic syndrome, of which anaemia (20-40%), fever (30%), hypertension (24%), hypercalcaemia (10-15%) and hepatic dysfunction (3-6%) are the most common.
