TY - JOUR AB - Adenomyotic cysts are small cysts with a diameter of <5 mm, usually containing hemorrhagic material. The present study reported on a patient with a large adenomyotic cyst with abnormally high serum levels of CA19‑9 (>1,000 U/ml) and CA125 (642 U/ml) and a complaint of pelvic pain. MRI scans were critical in diagnosing the case. Adhering to the principle of tumor‑free implantation, a laparotomy was performed. After the operation, six weeks were required to normalize the serum level of CA19‑9 and four weeks for CA125. Elevated tumor markers are frequently observed in malignancies, but the outcome reported in the present case was a benign lesion and the prognosis was favorable. In the present case, it was unusual that CA19‑9 was elevated in addition to CA125, as it is commonly reported that only CA125 is elevated in cases of large adenomyotic cyst.
