An ectopic pregnancy; the development of a fetus outside the uterus, most commonly in a fallopian tube.
From Greek 'ek-' (out) + 'kyesis' (pregnancy). The prefix 'ec-' means 'out of place,' combining with the root for pregnancy to describe this dangerous medical condition.
Before modern medicine, eccyesis was almost always fatal—it's absolutely gripping that ancient doctors had a specific word for this condition even though they couldn't diagnose or treat it, suggesting they recognized the pattern from tragic cases they couldn't save.
