Epithelial-myoepithelial carcinoma (EMC) is a rare malignant salivary gland tumor, which is especially uncommon in the minor salivary glands (MSG). We report literature review of EMC of the MSGs with our experience of two cases. Case 1 is a 75-year-old woman with a hard elastic mass in the hard palate, sized 2.5 × 2 cm without ulceration. Incisional biopsy was suggestive of pleomorphic adenoma. Tumor resection was performed with adequate surgical margin. Case 2 is a 44-year-old woman with a mass in the hard palate, sized 1.8 × 1.6 cm without ulceration. Incisional biopsy was suggestive of pleomorphic adenoma or a low-grade salivary gland carcinoma and intraoral tumor resection was performed. Both have good postoperative courses and are alive with no evidence of local recurrence or metastasis at 25 and 10 months. The Ki-67 labeling index in Case 1 and 2 were 10.6 and 3.8 %. Considering that the anatomy, structure, and size of salivary glands are quite different from MSGs, EMCs of the MSG cannot be predicted similarly to EMCs of the major salivary glands. The present review with 18 cases revealed no consensus on treatment methods for MSG cases other than surgery. |
