    ABSTRACT: We present clinical and radiological findings in a case of collecting (Bellini) duct carcinoma (CDC). This is a rare and aggressive kidney cancer originating from the distal renal tubule. The patient underwent radical nephrectomy and the pathological report showed trabeculopapillary, partially solid adenocarcinoma infiltrating the renal capsule and sinus. Immunohistochemical, as well as mucinocarminic and PAS staining studies are necessary for diagnosis of CDC. Surprisingly, one year follow-up studies were negative for recurrent disease. Chromosomal findings are usually different from most often diagnosed clear cell renal cell cancers. Findings from the literature are briefly discussed.

    ABSTRACT: Collecting duct carcinoma is a rare type of renal cell carcinoma that affects younger patients, and is associated with aggressive regional and distant spread. The clinical and pathological features of 6 patients with collecting duct carcinoma treated at a single institution are described. There were 6 patients with collecting duct carcinoma included in the University of California School of Medicine, Los Angeles, Kidney Cancer Database. Demographic, clinical, pathological and survival data were gathered. Average patient age plus or minus standard deviation was 56 +/- 11 years, and 5 of 6 had TNM stage IV disease. The average survival of these patients was 11.5 months (range 7 to 17). There was 1 patient who had TNM stage I disease and survived without evidence of disease at 5 years. Transient response to chemotherapy was seen in 1 patient. Collecting duct carcinoma is associated with poor prognosis. For the majority of patients surgical treatment will not result in a cure. Previously recommended chemotherapy and/or immunotherapy appears to have a limited role in treatment of this disease, and early detection may be the best method for prolonging patient survival.

    ABSTRACT: We present a case of collecting duct carcinoma (CDC) of the kidney exhibiting uncommon radiologic findings. A 67-year-old man had a history of hepatic resection for hepatocellular carcinomas. Follow-up CT revealed a left renal mass that presented an exophytic appearance with distortion of the renal contour. Since malignancy was suspected, the patient underwent a left radical nephrectomy with partial adrenalectomy and para-aortic lymph nodes dissection. Histologically, the majority of the tumor showed a tubular structure, and the rest was a solid area resembling transitional cell carcinoma (TCC). A diagnosis of CDC was made. In previous reports, common radiologic findings of CDC have been a medullary location and infiltrative appearance. Therefore, the outer contour of the affected kidney is usually maintained when the mass is relatively small. However, the present case did not show these common findings. In conclusion, the radiologic findings of CDC may be various and we should consider this tumor in the differential diagnosis of renal tumors.
