However, the tumor was surgically removed together with the left submaxillarygland and diagnosed as MUCOEPIDERMOID TUMOR by tissue examination. Exacerbation was not found for her life, but, metastasis to the lung, vertebra and skull appeared after about 9 months, and then, she died after bout 28 months postoperative course.In this case, mixed tumors of the salivarygland are histologically so variable that the examinational excision is not only unusefle for diagnosis but also harmful for prognosis.The tumor of the submaxillaryglands has to be considered for malignant and complete extirpation of the submaxillarygland, if necessary, resection of lymph tissues in the neighbourhood, is to be performed.
