Abstract
Argentaffin cells were searched for in the epithelial nests of 30 human Brenner''s tumors, with the Fontana-Masson stain for the screening. Although these cells were found in 5 tumors, ultrastructural examination of 1 case, in which the argentaffin cells were multiple, identified the cytoplasmic granules as lysosomes and not as amine precursor uptake and decarboxylation (APUD)-type granules. The epithelial component of Brenner''s tumors consists of urothelium only and does not include the cells containing argentaffin APUD-type granules.
