Background: Acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. Decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. Similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua (deciduosis) may occur.
