[Tubal choriocarcinoma. A case report (author's transl)].

The majority of the 82 cases of tubal choriocarcinoma reported in the published literature followed malignant transformation of a tubal ectopic pregnancy. The case presented was not related to ectopic pregnancy but was apparently the result of malignant changes in migrating trophoblastic elements during previous pregnancies not arriving at full term. The patient had two abortions by aspiration and had been on oral contraceptives ever since.

[A rare abdominal emergency: acute phlegmonous gastritis (author's transl)].

In the light of a series of recent observations and a personal case, the authors recall that acute phlegmonous gastritis is a rare disease usually secondary to a bucco-pharyngeal infective focus, characterised by an acute abdominal syndrome accompanied by a very severe infective context. Only laparotomy leads to the diagnosis. Since antibiotics, the mortality has regressed from more than 80% to less than 50%.
