[Deciduosis causing perforating appendicitis in the early postpartum period following caesarean section].

Case history of a 29-years-old primigravida is reported, by whom in the 39th week of the pregnancy an acute caesarean section was performed for intrauterine fetal distress. On the 5th postoperative day symptoms of acute abdomen developed, with typical signs of an appendicitis. On emergency laparotomy a perforated processus vermiformis had been removed, displaying gangrenous inflammation. Histological examination of the removed tissue revealed deciduosis, involving all layers of the intestinal wall. The article is the first Hungarian report on deciduosis involving the appendix, and the first international paper reporting on an appendicectomy for deciduosis following caesarean section summarizes the origin, the signs and the therapeutical consequences of this rare diagnostic entity.
