Multiple acinic cell carcinoma. Some histological and ultrastructural features of a case.
A case is presented of multiple acinic cell carcinoma, occurring synchronously in the left parotid gland and in the right submaxillary gland of a 75-year-old male patient. Fourteen cases of primary multiple acinic cell carcinoma have previously been reported, all bilateral parotid gland tumours. To our knowledge this is the first report of extraparotid localization of an acinic cell carcinoma in a patient presenting multiple salivary gland tumours. The histologic and ultrastructural characteristics of the tumours are described and a review of the literature is given.
