Parotid grand calculi in a 52-year-old man is reported. The examinations showed swelling of left parotid gland and a palpable small hard mass at the mid portion of the parotid duct and on the left side. CT and Echo were recommended for its diagnosis. CT showed a small high density area, and the Echo showed an acoustic shadow in front of the left parotid gland. The surgical operation was performed with a small external incision in the longitudinal direction along the parotid duct. After the operation, a cut-down tube with a diameter of 1mm was retained in the parotid duct, for preventing stenosis of the parotid duct. The stone was analyzed by infrared spectrometry, and was composed of calcium phosphate and protein.
