collecting duct renal cell carcinoma

Ductus-Bellini-Karzinom

(Sammelrohrkarzinom) in der Computertomographie axial und coronar bei einem 80-jährigen am unteren Pol der linken Niere. Der Tumor ist multipel ossär metastasiert.

Extrarenal

multiorgan metastases of collecting duct carcinoma of the kidney: A case series. A 55-year-old man with autopsy-confirmed collecting duct carcinoma and pulmonary, liver, and lymph node metastases. A. Computed tomography scan shows an enlarged right kidney and an ill-defined mass (arrows). B. Early phase computed tomography reveals slow and heterogeneous enhancement of the lesion. C. Delayed phase computed tomography reveals slow and heterogeneous enhancement of the lesion. D. Computed tomography scan through the upper lung shows multiple cavitary lesions (arrows). E. Autopsy specimen reveals hemorrhagic nodules with central cavities (arrows) in both lungs. F. Enhanced computed tomography shows a low-attenuation area (arrow) with minimal enhancement in S4 of the liver. G. Autopsy specimen demonstrates a mass in S4 (arrow) with hemorrhagic and necrotic changes. H. Enhanced computed tomography shows a marginally enhanced nodule in the para-aortic area. I. Gross examination reveals a lymph node with central necrosis (arrow).

Extrarenal

multiorgan metastases of collecting duct carcinoma of the kidney: A case series. A 70-year-old man with autopsy-confirmed collecting duct carcinoma and bony metastases. A. Unenhanced computed tomography shows a poorly defined medullary tumor with infiltrative growth. The renal contour is intact. B. Early phase enhanced computed tomography scan reveals mild enhancement of the lesion. C. Delayed phase enhanced computed tomography scan reveals mild enhancement of the lesion. D. Computed tomography shows osteolytic (thin arrows) and osteosclerotic lesions (thick arrows) in the ilium and sacrum. E. Photomicrograph (×200, hematoxylin and eosin stain) demonstrates osteosclerotic changes (thin arrows) and tumor cells (thick arrows). F. Photomicrograph (×200, hematoxylin and eosin stain) shows osteolytic changes (thin arrows) and tumor cells (thick arrows).
