Abstract
A panel of lectins chosen for its specificity for segments of the nephron was used in an avidin-biotin-peroxidase reaction to stain 13 human renal oncocytomas and a specimen of oncocytomatosis. The lectins were derived from Lotus tetragonolobus, Glycine max, Dolichos biflorus, and Arachis hypogaea. Two patterns predominated: one of staining with the lectins of D biflorus and G max, suggesting distal tubular or collecting-duct differentiation, and one of staining with the lectin of L tetragonolobus, suggesting proximal tubular differentiation.
