Abstract :
Decidua is endometrium that is hormonally prepared for pregnancy. Decidual cast is the entire sloughed endometrium that takes the form of the endometrial cavity. It is a rare entity which is the result of high progesterone on uterine endometrium. It has association with intrauterine pregnancy, ectopic pregnancy, incomplete abortion and in non-pregnant states with the use of hormonal pills etc. We are here presenting a case series of decidual casts. We observed that all our patients had a similar history of recent intake of hormonal contraceptives followed by bleeding and passage of fleshy mass from vagina. The differential diagnosis of passage of mass per vaginum includes conditions ranging from benign to malignant, therefore, our study emphasizes the importance of considering it in mind, since it mimics malignancy but is not a signal of a serious condition.
