軟口蓋の多形腺腫より発生したMyoepithelial Carcinoma例

抄録

We report a case of myoepithelial soft-palate carcinoma, a rare salivary gland tumor. A 72-year-old woman seen for oral-cavity discomfort, was found in magnetic resonance imaging (MRI) to have a well-defined solid mass in the submucosal soft palate. She had had a tumor at the same site surgically removed about 30 years earlier. The tumor was totally resected and histopathologically diagnosed as myoepithelial carcinoma arising from pleomorphic adenoma. The woman is currently disease-free for four years and two months postoperatively.
