Abstract
The primary nasopharyngeal mixed tumor has rarely been reported, although minor salivary glands are normally found in the nasopharynx. Recently, we experienced a case of primary nasopharyngeal malingnant mixed tumor.
A 79-year-old female had been suffered from the left impaired hearing for several months and the left nasal obstruction for several years. Physical examination revealed a large tumor in the nasopharyngeal space which pressed the soft palate forwards.
Under general anesthesia the tumor was surgically removed. At surgery, it was confirmed that the tumor originated from the nasopharynx.
Mixed tumor was diagnosed by microscopic tissue examination. And ultrastructurally, malignant cells were certified.
