Tyrosine-rich crystals in pleomorphic adenomas of parotid glands.
Histochemical methods for proteins were applied to crystals found in pleomorphic adenomas of the parotid. Positive reactions were obtained with methods for tyrosine, tryptophan, arginine and sulphydryl groups, and indicate a greater complexity of composition than has previously been acknowledged.
