Renal carcinoma associated with polycystic kidneys: occurrence after chronic hematuria and hypertension

Metastatic Renal Cell Carcinoma in a Patient With Autosomal Dominant Polycystic Kidney Disease

ABSTRACT

Autosomal dominant polycystic kidney disease (ADPKD) manifests as multiple cysts in the kidneys and liver but can also present with musculoskeletal and cardiovascular abnormalities. ADPKD patients are at increased risk for renal cell carcinoma development. We show the FDG PET/CT findings in a patient with renal cell carcinoma secondary to ADPKD and complicated by worsening pulmonary metastasis. The primary renal tumor shows intense FDG uptake despite no suspicious features with contrast CT.

Renal cell carcinoma in the presence of adult polycystic kidney disease

A case of autosomal dominant polycystic kidney disease associated with widely metastatic renal cell carcinoma is reported. The patient had presented with pneumothorax, weight loss, leukocytosis, lytic bone lesions, and hypercalcemia. Despite intensive diagnostic search for a neoplasm, no firm evidence of malignancy was found. However, at the autopsy, widely metastatic, papillary renal cell carcinoma was found originating in the left kidney. Many metastases showed central necrosis mimicking small cysts.

Cystic kidneys: an enigma evolves

Substantial contributions to the field of RCD have been made over the past 15 years. Most intriguing is a growing awareness of acquired RCD and its complications. Data have been published and are reviewed here in support of a possibility that APKD and RCD acquired during hemodialysis are premalignant lesions. More data are needed before the possibility can be confirmed or denied. The collection of these data is an immediate need in the field of RCD.

Renal cell carcinoma in polycystic kidneys: case report and review of literature

A case of polycystic kidneys associated with a sarcomatoid variant of renal cell carcinoma is reported. The patient presented with hilar lymphadenopathy, para-aortic lymph node enlargement with an abnormal lymphangiogram and splenomegaly. Biopsy of the hilar lymph node, para-aortic lymph node and spleen showed reactive hyperplasia only but biopsy of the left kidney, liver and mesentery revealed poorly differentiated renal cell carcinoma with sarcomatous changes.
