Epithelial-myoepithelial carcinoma (EMC) of the parotid gland, a rare low-grade malignant tumor, consists of ductal and myoepithelial cells. We report an extremely rare case of giant EMC of the parotid gland. A 71-year-old man seen for a 13 cm ×12 cm tumor of the left parotid gland was found in magnetic resonance imaging (MRI) to have multiple cystic lesions and a solid lesion appearing to arise from the parotid gland. The completely resected tumor was histopathologically diagnosed as EMC. The postoperative course was uneventful and 8-month follow-up showed no clinical evidence of recurrence. We discuss EMC pathology and review 16 cases of giant parotid tumor in Japan in this report.
