Abstract

This paper reported a rare case of acinic cell tumor which arose in the left parotid gland that seemed to infiltrate and proliferate along the parotid duct and formed a ulcer at the orifice of the parotid duct.
The patient was a 75 year-old woman. She noticed a swelling with dull pain in the posteroinferior region of the left auricle 23 years previously.
Pathological diagnosis of the ulcer by biopsy was acinic cell tumor.
Only the tumor was excised followed by chemotherapy with FT-207 and PSK.
The tumor was multinodular and encapsulated in the greater part but infiltrated out of the capsule in a part. In spite that the capsule was broken at the operation which seemed to worsen the prognosis, there is no evidence of recurrence or metastasis in the patient as of 3 years 7 months after operation.
