Abstract
On June 7, 1978, a 66-year-old unmarried Japanese woman suffering from liver fibrosis and SLE died of hepatic coma. Autopsy revealed cysticercus cellulosae in brain, heart, lung and subcutaneum, which was calcified and old. She had a past history of once living in Manchuria and repatriating in 1946.
Study of literature: 1. 354 cases of cysticercosis, including 302 Japanese, 19 Chinese, 12 Korean, and 18 unknown cases, were reviewed out of 219 literatures. 2. In “Annual of the Pathological Autopsy Cases in Japan, 1958-1975”, 6 cases were observed out of about 330, 000 cases (0.002 %) . 3. In Japanese cases, three groups could be classified, namely group-I (53%) —cases in Okinawa, group-II (41%) —cases once in abroad (Manchuria, China & Siberia 94%) and group-III (4.6%) —cases infected in Japan. 4. Historically, the Japanese cases have been observed since the first report in 1908, 3 cases (1908-1915, I-0, II-100, 111-0%), 2 cases (1916-1925, 0, 100, 0%), 12 cases (1926-1935, 25, 58, 17%), 203 cases (1936-1945, 76, 23, 0%), 53 cases (1946-1955, 2, 83, 13%), 17 cases (1956-1965, 6, 76, 18%), 9 cases (1966-1975, 13, 67, 22%) and 3 cases (1975-, 0, 100, 0%) .
Conclusion: Japan had probably no expierince of the contamination of cysticercosis until the Manchurian expedition in the Japanese-Russan War (1904-5) . The expedition and the migration became increased and the contamination of cysticercosis became simultaneously increased like oversea wave from Manchuria. Those phenomena had been continuing untill the end of the World War II (1945) and the final repatriation from Manchuria. In Okinawa, where the habit of pig breeding is common, cysticercosis became endemic. In Japan excluding Okinawa, soon after the disappearance of the contamination, cysticercosis became repidly dissapeared. Recently, the cases of cysticercosis including ours were only accidentally found by X ray films or autopsy, the most of which were supposed to be infested in Manchuria more than 30 years ago.
