A 33 year old woman who was living in an apartment by herself died from acute CO poisoning, a case of incomplete combustion of city gas. The CO-hemoglobin concentration was 70%.
At the time of autopsy, about 80 ml of liquid blood and tip of the thumb grumose tumor were attached to the dextra fimbriae tubae. Histologically, this grumose tumoe consists of Langhans' cells and choriomic syncytium and miscarriage of one month's pregnancy was noted. However, in this case, it was extopic pregnancy and a miscarriage dextra gra-viditas tubaria ampullaris. The said liquid blood in the abdominal cavity was that from miscarriage. Further, it was noted that an IUD (Intra Uterine Device) had been inserted in the uterus, but it was impossible to clarify the relationship between IUD and tubular pregnancy.
The CO-hemoglobin concentration of the liquid blood which had been observed in the abdominal cavity was 70%. This signifies that CO poisoning had stimulated tubal abortion which resulted in the 80 ml of blood observed in the abdominal cavity.
