Collecting duct carcinoma of the kidney is an unusual variety of renal carcinoma considered to arise from the epithelium of the collecting ducts. We recently experienced an case of fine needle aspiration cytology of collecting duct carcinoma of the kidney in a 17 year-old girl. The smear revealed many cellular clusters of ordinary papillary pattern, characterized by clumping of cells with nuclear overlapping, in a slightly necrotic background. The tumor cells had abundant delicate granular cytoplasm with some having vacuolation. The nuclei were only slightly pleomorphic with somethat coarse chromatin and one or more small nucleoli. Some nuclei showed irregular nuclear membrane and nuclear groove. A few polmorphs were also present.
