Papillary renal cell carcinoma(RCC) is an uncommon subtype of RCC that has distinctive gross, histologic, and cytogenetic features. The cytologic features of FNA are abundant papillary clusters and relatively few single cells. The cells are usually small and contain uniform nuclei; numerous macrophages with foamy cytoplasm are often found in the background. We describe a case of papillary renal cell carcinoma evaluated by fine needle aspiration cytology(FNAC) in a 42 year-old man. The smear showed a few papillary clusters and numerous macrophages with foamy cytoplasm in the background. With adequate cellularity, papillary RCC can be distinguished reliably from non-papillary RCC by FNAC.
Key Words: Papillary renal cell carcinoma; FNAC
