1/118. Bilateral renal masses after local bacillus Calmette-Guerin therapy for postcystectomy ureteral cancer.bacillus Calmette-Guerin was administered through the ileal conduit of a 63-year-old man with upper tract recurrence of transitional cell carcinoma. Subsequent computed tomography showed bilateral renal masses, which were granulomatous at pathologic examination. The bacilli likely reached the kidneys via proven ileoureteral reflux. patients with reflux may benefit from antituberculous prophylaxis.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/118. The use of fluconazole as a local irrigant for nephrostomy tubes.OBJECTIVES: Few data exist concerning the combined use of fluconazole systemically and as an irrigant for nephrostomy tubes in a patient with renal candidiasis. The patient described here presented with renal fungal balls obstructing the drainage of urine from her nephrostomy tubes. methods: Twelve months after chemoradiation for a stage IIB squamous cell carcinoma of the uterine cervix, a 35-year-old woman presented with renal obstruction necessitating insertion of ureteral stents. After 6 months of chemotherapy, the patient developed uremia. After nephrostomy tubes were placed, renal candidiasis was noted, and fluconazole was begun systemically. When the renal candidiasis failed to clear, nephrostomy tube irrigations were begun. RESULTS: Fourteen days of therapy with fluconazole resulted in the resolution of the uremia. The patient died 6 months later with her nephrostomy tubes in situ and without evidence of candidiasis in her urinary tract. CONCLUSIONS: The patient described was successfully treated without having to remove her nephrostomy tubes. Two other authors have reported the successful use of fluconazole irrigation to treat candidiasis in nephrostomy tubes that was unresponsive to systemic fluconazole. Before the appearance of these reports, the best results were obtained with removal of the catheter in renal candidiasis.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
3/118. Foreign-body granuloma of the kidney: CT, MR and pathologic correlation.The differential diagnosis of renal masses containing fatty foci is limited to a small number of well-defined tumors, angiomyolipoma being the most frequent. In recent years clear cell carcinomas with intratumoral fatty foci have been reported, due to either entrapment of local fat or to regressive adipose metaplasia. Demonstration of focal calcifications is a valuable sign, being relatively common in carcinomas while rare in more benign lesions. We report a case of a foreign-body granuloma of the kidney, containing both calcifications and foci of fat. The value of this case, in our opinion, is that it demonstrates that detection of the previously mentioned features in a renal mass does not necessarily imply a presumptive diagnosis of renal cell carcinoma.- - - - - - - - - - ranking = 3keywords = carcinoma (Clic here for more details about this article) |
4/118. Papillary microcarcinoma of the thyroid gland in renal transplant patients.Among organ transplant recipients there is a world wide increase in the number of de novo tumors as well as a decrease in the time of the first appearance after the transplantation. Between 1973 and the 31st of August 1999 1709 cadaver renal allograft transplantations were performed in our Department. Four thyroid cancers were detected among the renal transplanted patients. Two of them proved to be papillary microcarcinomas. Although the elevated risk of thyroid cancers is well established in the literature papillary microcarcinomas have never been reported before in an immunosuppressed patient. Authors highlight that the thyroid gland should always be carefully checked in organ transplant recipients, since better survival might be achieved even in the immunosuppressed population. Metastatic tumor is relatively benign which is in correlation with the literature, but there has been little experience in organ transplanted patients so far.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |
5/118. Ectopic localisation of adrenal cortex.We present a case of concurrence of ectopic adrenal cortex with a renal cell carcinoma. The diagnosis of the accessory adrenal tissue was made by CT-guided biopsy. With this case report, we draw attention to a specific differential diagnostic problem, policy and to the MR characteristics of ectopic adrenal cortex.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
6/118. Renal actinomycosis mimicking renal carcinoma.The case of a 52-year-old man is reported who presented with night sweats and slight debilitation. Upon CT scan a left-sided renal mass with centrally liquefied areas was detected. The patient underwent nephrectomy for suspected renal cancer with central necrosis. Histologically, the diagnosis of renal actinomycosis was established based on the detection of sulphur granules. actinomyces israelii is an anaerobic gram-positive bacterium that may cause localized tumour-like infections mainly in the craniocervical region and exceptionally retroperitoneally. Renal actinomycosis is a rare differential diagnosis of renal masses. As nephrectomy may prove hazardous in these cases, the diagnosis should be attempted pre-operatively by ultrasound-guided aspiration and consecutive antibiotic treatment. In selected cases surgery could be avoided at all.- - - - - - - - - - ranking = 4keywords = carcinoma (Clic here for more details about this article) |
7/118. Calyceal rupture and perirenal urinoma as a presenting sign of recurrent ovarian cancer.BACKGROUND: rupture of the urinary collecting system with peripelvic extravasation of urine is an uncommon pathologic condition usually associated with ureteral obstruction from calculi. CASE: We report a patient with calyceal rupture and peripelvic extravasation of urine secondary to distal ureteral obstruction by recurrent ovarian carcinoma. Diagnosis was established with computed tomography and renal scans. Placement of an indwelling ureteral stent via a nephrostomy resolved the urinoma. CONCLUSION: Gynecologic oncologists should be aware that calyceal rupture is a potential complication of gynecologic malignancy. Causes of perirenal urinary extravasation and approaches to diagnosis and management are reviewed.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
8/118. Stauffer's syndrome--diagnostic help in hypernephroma.Dysfunctions of the liver known as Stauffer's syndrome have been observed in various cases of renal cell carcinoma. In a case history of renal cell carcinoma the most common clinical symptoms and laboratory findings of early presentation are displayed. During the first clinical investigations the evidence of typical laboratory values indicating unusual hepatic dysfunction, did not lead to the true diagnosis until symptoms became clearer two year later. Intensified renal diagnosis are asked for in any case of unexplained abnormalities of liver function in order to exclude a renal cell carcinoma or to force its early diagnosis.- - - - - - - - - - ranking = 3keywords = carcinoma (Clic here for more details about this article) |
9/118. Malakoplakia of the kidney--a case report.Malakoplakia is a rare disease expressed as a special type of inflammatory reaction to infection with various bacteria and fungi. We present a case of renal malakoplakia in a 30-year-old female patient. The symptoms were not characteristic enough for making the ture diagnosis preoperatively. A preoperative diagnosis of renal cell carcinoma was made in this case.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
10/118. Transitional cell carcinoma of the renal pelvis presenting as a renal abscess.We report on a 76-year-old woman who was diagnosed with a primary renal abscess of the left kidney. After percutaneous drainage, no clinical improvement was observed. Surgical exploration and nephrectomy were performed. The histologic evaluation revealed an unsuspected transitional cell carcinoma of the renal pelvis, which had been misinterpreted as a primary renal abscess. Malignancy must be considered as an underlying cause for the formation of a renal abscess, especially if no other predisposing factors such as diabetes mellitus or urinary stones are present.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
