同時性両側上顎癌の1症例

抄録

43 cases of primary carcinoma of the bilateral maxillary antrums had been reported in Japanese literature between 1937 and 1978.However, in the field of oral surgery there has been no report on this type of the maxillary carcinoma.
This paper described a case of the synchronous carcinoma of the bilateral maxillary antrums in a 72-year-old female who was asymptomatic subjectively and objectively at the first visit to our clinic with complaint of unstability of the upper denture. However, radiographic and C. T. scanning examinations revealed destructive and absorptive changes in the bilateral maxilla and the zygoma. The histopathological examinations of the specimens taken from the bilateral antrums revealed undifferentiated squamous cell carcinoma.
Based on careful analysis of the past history, clinical findings and histopathological evidences, we concluded that this tumor had developed independently in each sinus and was a synchronous primary double cancer.
