Well-differentiated endometrial adenocarcinoma in an infertility patient with later conception. A case report.

BACKGROUND: The incidence of well-differentiated endometrial adenocarcinoma in reproductive-age women is approximately 5%. When the women desires to retain her future fertility in light of this diagnosis, choices of surgery vs. medical therapy may present a dilemma for both the physician and patient. CASE: A young infertility patient with well-differentiated endometrial adenocarcinoma conceived by ovulation induction and intrauterine insemination after medical therapy. She subsequently delivered vaginally, and follow-up dilatation and curettage revealed no evidence of recurrent carcinoma.
CONCLUSION: This case illustrates that with close observation by endometrial sampling for histologic diagnosis and follow-up, medical therapy can be an option for treating this condition to allow future fertility. The patient must be extensively counseled, however, concerning the nearly 33% chance of progression or recurrence of disease. One must also stress the importance of frequent evaluation of symptoms and endometrial pathology postpartum, with endometrial sampling as indicated and discussion of definitive surgical therapy once fertility is no longer desired.
