Endometrial adenocarcinoma in spontaneous abortion: two cases and review of the literature.

OBJECTIVES To report two extremely rare cases of endometrial adenocarcinoma established during the first trimester. CASE PRESENTATION A 40-year-old (gravida 0, para 0) and 33-year-old (gravida 4, para 0) woman, were diagnosed with a well-differentiated adenocarcinoma after a dilatation and curettage (D&C) for spontaneous abortions at 8 and 9 gestational weeks, respectively. CONCLUSIONS Thirty-six cases of pregnancy-associated endometrial cancer and 20 cases of first trimester pregnancy concurrent with endometrial carcinoma have been reported as present cases in the literature. Interestingly, 15 including our two cases were detected for spontaneous abortions in first-trimester suggesting a causal correlation between endometrial adenocarcinoma and spontaneous abortions. Repeated D&C and progesterone administration may be appropriate for patients who wish to preserve fertility.
