Endometrial polyp filled with gestational tissues remained u
Recurrent pregnancy loss (RPL) is a common disease, which presents as two, three or more failed pregnancies. It is attributed to many risk factors, yet half of the cases are idiopathic. This report presents a case of a 44-year-old woman with a complaint of secondary infertility for 10 years and a history of three spontaneous abortions.

Blood tests and images showed no abnormalities, except for hysteroscopy which showed a polyp-like mass. Pathology revealed an endometrial stroma showing severe decidualization with a lot of gestational villi showing fibrosis and hyaline degeneration, features of old gestational product death, with no glands crowding or cellular atypia.

In this case, the conception products were not preceded with a miscarriage and did not cause any symptoms indicating its existing. The asymptomatic endometrial polyp filled with fibrotic gestational villi without a prior miscarriage is an unprecedented case in the medical literature. Therefore, should be taken into consideration while investigating for infertility-related EP. Also, emphasize the importance of pathological examination in infertility investigation which enables us, besides the clinical history, to distinguish the case from other findings that might present in an EP which can cause gestational impairment and differ in the treatment method.
