• We have utilized three cotton dyes, Pagoda Red, RIT Scarlet No. 5, and RIT Cardinal Red No. 9, for the microscopic demonstration of amyloid in cutaneous histopathology. All three dyes stained amyloid specifically, yielding a bright orange color. The preparation of staining solutions and the staining procedure are simple, practical, and can be applied routinely in a dermatopathology laboratory.
