View from beneath: pathology in focus bilateral acinic cell tumours of the parotid gland.

A 55-year-old woman was operated because of bilateral parotid tumours which appeared with an interval of three years. Histopathologically, both of the tumours had characteristics typical of acinic cell tumour, so-called clear cell type. Both tumours were regarded to be multifocal. In the case of bilateral parotid tumours, acinic cell tumour should also be kept in mind and total parotidectomy is the treatment of choice.
