Wagner P, et al. - In a large population-based, single center cohort of 10,756 patients who had a hysterectomy for presumed benign conditions between 2003 and 2016, researchers assessed the incidence and features of unexpected malignant pathologies of the uterine corpus. Out of 10,756 patients, 45/10,756 (0.42%) had unexpected uterine malignancies., with 33/45 (73.3%) and 12/45 (26.7%) being endometrial carcinomas (UEC) and uterine sarcomas (UUS), respectively. FIGO IA, FIGO IB, and FIGO stage II disease were seen in 27/33 (81.8%), 5/33 (15.2%), and 1/33 (3%) cases of UEC, respectively. Findings revealed unexpected malignancies of the uterine corpus (UUM) was a rare diagnosis. Preoperative diagnosis was difficult due to the tendency of UUM to be early stage. A generally favorable patient outcome was seen with UEC. All preoperative findings should be considered to opt for the appropriate surgical approach for hysterectomy for a benign indication. The residual risk of UUM should always discussed with the patients.
