Abstract

Abstract: Collecting duct carcinoma is a rare neoplasm of the kidney, accounting for only 1–2% of renal tumors. These tumors arise from the principal cells of the renal collecting ducts of Bellini. The majority of patients have lymph node involvement and metastases to lungs, liver, bone, adrenal glands, and brain. We present a case of a 48 year old woman who came to the hospital with a clinical presentation suspicious for pneumonia. One week later her symptoms aggravated. A CT chest and abdominal imaging showed bilateral pulmonary infiltrates, retroperitoneal lymphadenopathy, and left hydroureteronephrosis. She expired after developing acute respiratory failure. An autopsy was performed which revealed chylopericadium of 150 cc; bilateral reticular pattern on the surfaces of the lungs; neck, mediastinal and retroperitoneal lymphadenopathy, and a 5.1 cm left kidney mass located in the mid portion medulla. The kidney tumor was a rhabdoid collecting duct carcinoma. The lungs showed diffuse subpleural lymphangitic spread of the carcinoma. We report a rare case of chylopericardium due to lymphangitic carcinomatosis from a 5.1 cm rhabdoid collecting duct carcinoma not suspected clinically or radiologically. This case highlights the importance of performing autopsies in an era when clinicians heavily rely on high-tech imaging diagnostic modalities.
