[A case of metastatic lung tumor of the colon cancer with ova of schistosoma japonicum in the resected lung specimen].
A 69-year-old man underwent right middle lobectomy because of the tumor lesion in the right middle lung. He had ever been in Celebes and China (riverside area of the Yangtze), the infected area of schistosomiasis japonica, for military service during the World War II. Resected lung specimen was carefully examined at the department of pathology in our hospital. Several ova of Schistosoma japonicum were discovered scattered in the specimen, and the pathological feature of the lung lesion was revealed to be metastasis of the sigmoid colon cancer which was resected 4 years ago at a certain hospital. The ova of Schistosoma japonicum were also distributed near the colon lesion. Recently in Japan, it is said, acute infected case of schistosomiasis japonica has been ceased, however, in cases of chronic stage of this disease, hepatoma or lower intestinal cancers are still discovered through the careful follow up study.
