Abstract
The malignant epipharynx tumor is a relatively rare disease, which occurs oftener in Orientals, especially in Chinese. It is noticeably difficult for treatment and the prognosis is very bad. In this report the author made observations on 72 cases of malignant epipharynx tumor, which were brought into postmortem exa mination in Japan with the special reference to the state of their metastasis.
1. Visceral metastasis was seen in 37 cases (69.8%) among 53 of cancer. The site of metastasis were mainly in bone, liver and lung. While, visceral me tastasis was 8 (47.0%) among 17 of sarcoma, and chiefly in spleen and adrenal gland.
2. Lymphonode metastasis was 36 cases (67.9%) among 53 of cancer and 12 cases (70.6%) among 17 of sarcoma. The site of metastasis in both cases were mainly in cervical lymphnodes. But sarcoma showed the general tendency of having distant metastasis, such as in the hilus of the lung, retroperitoneal space, the intermesenteric lymphonodes and so forth.
