We present a rare case of epithelial-myoepithelial carcinoma (EMC) arising in right side of the soft palate that was accompanied by cervical lymph node tuberculosis.A 72-year-old woman was referred to our hospital because of swelling of the right side of the soft palate. Intraoral examination revealed a submucosal mass lesion measuring 14 × 15mm in the soft palate. Contrast enhanced computed tomography showed a mass on the soft palate and cervical lymph node enlargement with ring enhancement. Magnetic resonance imaging and ultrasonography also revealed cervical lymphadenopathy. Fluorodeoxyglucose positron emission tomography (FDG-PET) showed intense focal FDG uptake in the enlarged lymph nodes, but not in the soft palate. Before surgery, the soft palate lesion underwent a biopsy, and the histopathological diagnosis was EMC. Thus, the enlarged cervical lymph nodes were diagnosed as EMC metastasis. Tumor resection of the soft palate and ipsilateral radical neck dissection were performed. Postoperative histopathological examination revealed EMC of the right soft palate and cervical lymph node tuberculosis. After surgery, antituberculous agents were administered to treat cervical lymph node tuberculosis.
