Association of renal cell carcinoma (RCC) with renal calculi is very rare. Herein we report a case of RCC developing in a non-functioning kidney containing multiple renal and ureteric calculi. Histologically, the kidney, in addition, revealed changes of xanthogranulomatous pyelonephritis (XGP). XGP can be confused clinically, grossly and microscopically with RCC. In the present case both were coexistent and thus make it interesting.

An unusual case of a 44-year-old male renal transplant recipient who developed bilateral xanthogranulomatous pyelonephritis (XPN) of his native kidneys is presented. Bilateral nephrectomy specimens showed classic features of XPN. In addition, there was amyloidosis involving both kidneys and a small renal cell carcinoma in the left kidney. To the best of our knowledge, such a combination of pathologic conditions in one patient has not been previously reported.

We report a case of Stauffer's syndrome, characterized mainly by cholectasis, that occurred in a patient with benign intracystic renal haematoma and subsided after nephrectomy. Stauffer's syndrome was recognized, in 1961, as a paraneoplastic manifestation, usually associated with hypernephroma. This syndrome has been reported in only 2 cases of benign renal disease, which was a pseudotumoral xanthogranulomatous pyelonephritis.

A case of focal xanthogranulomatous pyelonephritis (XGP) with an associated renal cell carcinoma is presented. The tumor was discovered incidentally during a general surgical procedure. Subsequent evaluation showed a 3 cm mass in the lower pole of an otherwise normal kidney with no evidence of calculus or infection. Radical nephrectomy revealed classic findings of focal XGP with coexistent clear cell carcinoma. The literature describing the rare association between these conditions is reviewed.

Lymphocyte subsets were examined in renal cell carcinoma (TILs), adjacent non-tumor renal tissue and peripheral blood (PBLs) by flow cytometry and histochemistry in eighteen patients with renal cell carcinoma. CD5-positive cells were predominant in the TILs in 14 patients. In the renal cell carcinoma tissue, CD8-positive cells were predominant over CD4-positive cells, resulting in a less than unity ratio of CD4/CF8-positive cells. The lymphocyte number was significantly in adjacent normal renal tissue than in renal cell carcinoma. However, lymphocyte subsets ratios were not significantly different between these two tissues. PBLs showed the same proportions (CD4/CD8 mean 1.9 +/- 0.8) as the previously published healthy controlled data. The proportions of CD8-positive cells were significantly increased (p less than 0.05) and those of CD4-positive cells were also significantly decreased (p less than 0.01) in the TILs. The infiltrating pattern of TILs in 17 patients was divided histochemically into cluster (N = 7), single (N = 4), and mixed types (N = 6). The cluster and mixed types were significantly more common in grade 1 tumors and the single type was more common in the grade 2 tumors (p less than 0.05). The pT3 tumors showed the single type of TIL infiltration pattern, but showed no significant difference. In the cluster pattern of TILs, CD8-positive cells were surrounded by CD4-positive cells. Non-tumorous kidneys showed no infiltration of lymphocytes, except in 2 patients of pyelonephritis. These results suggest that cytotoxic T-cells stained as CD8 play an immunoreactive role against renal cell carcinoma.

Fine-needle aspiration cytology of xanthogranulomatous pyelonephritis in a fifty-seven-year-old Japanese woman is reported. Foamy cells and cells showing a gland-like pattern originating from degenerative renal tubules were found in the aspirated smears. Multinucleated giant cells and cells with pale yellowish cytoplasm were seen in the imprint smears at operation. These findings were diagnostic for xanthogranulomatous pyelonephritis. The cytologic diagnostic differences among xanthogranulomatous pyelonephritis, well-differentiated renal cell carcinoma, and renal oncocytoma are also described.

Xanthogranulomatous pyelonephritis is a rare and particularly aggressive variant of chronic destructive pyelonephritis. Even when all modern diagnostic possibilities are exhausted, it is often not possible to distinguish xanthogranulomatous pyelonephritis from a renal cell carcinoma preoperatively. In clinical practice false diagnoses are therefore frequent. The coexistence of xanthogranulomatous pyelonephritis and renal cell carcinoma is extremely rare. We report 2 such cases. In 1 case surgery was performed on the kidney affected by xanthogranulomatous pyelonephritis using a renal sparing technique.

A case of perinephric xanthogranulomatous pyelonephritis is presented. Ultrasonography and X-ray computed tomography (X-CT) showed a mass on the posterior aspect of the right kidney, causing us to suspect right renal cell carcinoma. Pyelography showed a deformity of the right renal calyces. From angiographic results, we considered the possibility of hypovascular renal cell carcinoma, subcapsular tumor, or retroperitoneal tumor. The mass was diagnosed pathologically as perinephric xanthogranulomatous pyelonephritis.

We report the results of clinicopathological and histochemical studies on 64 renal adenomas found in 22 patients. We selected typical renal adenomas for these studies, discarding borderline lesions. The ages of the patients ranged from 42 to 84 years, with an average of 61 years. Male to female sex ratio was 6.3:1. The background conditions included renal cell carcinoma, long-term dialysis, chronic glomerulonephritis, pyelonephritis, hydronephrosis and polycystic kidney. The sizes of the tumors ranged from 0.1 to 2.3 mm in maximum diameter, with an average of 0.9 mm. All the tumors were located in the cortex, especially in the superficial one-third. The cytoplasm of the tumor cells was predominantly eosinophilic, and the tumor structure was predominantly papillary. Histochemical study of 19 adenomas from 13 patients demonstrated that all of the adenomas from 13 patients demonstrated that all of the adenomas were positive for EMA, and for at least one marker of the distal tubulus, i.e., DBA, PNA, SBA and PKK1, and that 9 adenomas were positive for at least one marker of the proximal tubulus, i.e., LM1 and LTA. Renal adenomas had predominant histochemical features of the distal tubulus, suggesting differentiation to a distal tubulus-like histology.

Epidermoid carcinoma of the kidney is a rare malignant tumor, characterized by high invasiveness, poor prognosis, and the association of renal stone and renal infection. Very little reports about its sonographic appearance were mentioned in the literature. We present a case of epidermoid carcinoma of the kidney. Its ultrasonography showed a heterogeneous renal mass with perirenal and pararenal invasion, destruction of the renal pelvis, and preservation of enlarged reniform outline. Although this tumor should be differentiated with renal cell carcinoma, transitional cell carcinoma, renal metastatic tumor, renal lymphoma, renal infarction, focal bacterial nephritis, and xanthogranulomatous pyelonephritis etc., we think we should put epidermoid carcinoma of kidney into consideration when a renal tumor mass presents with perirenal and pararenal invasion, destruction of the renal pelvis, and preservation of enlarged reniform outline in sonography, and hypovascularity in angiographic study.
