Postmenopausal giant uterine adenomyoma with adipose metaplasia: A case report and literature review.

RATIONALE: Uterine adenomyomas (UAs) are common benign tumors, usually not exceeding 280 g or the weight of the uterus at 12 weeks gestation. Postmenopausal giant UAs of diameter larger than 20 cm are rare, as well as steatosis, but curable by surgical excision. Few cases of postmenopausal giant UAs have been reported.

PATIENT CONCERNS: Herein, we report a case of a 70-year-old female patient who presented with a giant pelvic tumor of about 20 cm × 18 cm × 20 cm with postmenopausal vaginal bleeding, and whose radiographic manifestations did not exclude the possibility of uterine malignancy.

DIAGNOSES: Histopathology confirms an adenomyoma with partial adipose metaplasia.

INTERVENTIONS: We did an open laparotomy of hysterectomy, bi-adnexectomy, and pelvic adhesion release for the patient.

OUTCOMES: Pathology revealed adenomyoma with adipose metaplasia. The patient recovered well and was discharged on postoperative day 7 with satisfactory follow-up.
