abstract

  • Papillary cystadenoma of the epididymis is an uncommon benign tumor associated with von Hippel-Lindau disease. Since metastatic renal cell carcinoma may be histologically similar to papillary cystadenoma, and both are associated with von Hippel-Lindau disease, differentiation between these two entities may be difficult. We performed lectin histochemistry studies on three papillary cystadenomas and compared the results with the staining observed in epididymal ducts, epididymal efferent ductules, and three renal cell carcinomas. Common positive staining was observed following incubation with soybean agglutinin in epididymal ducts and two of the three papillary cystadenomas, while the three renal cell carcinomas did not stain. When epididymal tumors histologically consistent with papillary cystadenoma fail to react with soybean agglutinin, thorough clinical evaluation for an occult renal cell carcinoma should be performed.
