A case of myoepithelioma occurring in the parotid gland of a 16-year-old male is reported. The tumor was gourd-shaped and firm in consistency, surrounded by a thin capsule, and was composed of spindle cells with eosinophilic cytoplasm and oval nuclei. The nuclei containing discernible nucleoli, were generally hyperchromatic. Ultrastructually, the cells contained many microfilaments about 6 nm in diameter. Based on these observations, this tumor was classified as myoepithlioma.
