抄録

This report describes a case of small cell carcinoma which originated from the sphenoid sinus. A male patient aged 54, complaining of diplopia, right facial hypoesthesia and severe headache, was admitted to our hospital. A CT scan and MRI showed a tumor shadow occupying the entire sphenoid sinus and extending to the skull base and the epipharynx. The tumor was diagnosed as a small cell carcinoma based on a punch biopsy of the mucous membrane of the epipharynx obtained through the nasal cavity. As the tumor extended widely to the skull base, treatment by external irradiation and chemotherapy was selected. One year from the initiation of treatment, the tumor has been significantly reduced and the patient's neurological symptoms have improved.
