Abstract
Collecting duct carcinoma is a rare renal malignant neoplasm, arising from the medullary collecting duct and accounting for less than 1% of renal cell carcinomas. It is more common in middle-aged men and is usually presented with hematuria, abdominal mass and back or flank pain. Its immunohistochemical analysis detects the expression of various markers, such as low and high molecular weight keratins, Ulex europaeus agglutinin-1, epithelial membrane antigen and peanut lectin. Here, we present a case of a 29-year-old woman with CDC presented with back pain and supraclavicular lymphadenopathy that produced carcinoembryonic antigen and CA-125.
