title: Dedifferentiated acinic cell (acinous) carcinoma of the parotid gland.
abstract: Otolaryngologists-head and neck surgeons and surgical pathologists should be aware of the potential for acinic cell carcinomas to dedifferentiate so that adequate histologic tumor sampling can be performed. Dedifferentiated acinic cell carcinoma is a highly malignant, newly recognized parotid malignancy. Clinical clues that may help identify this more ominous lesion must be recognized.
