Abstract

Endometrial cancer, the fourth most common cancer affecting women in the USA, typically recurs locally or can invade regional lymph nodes and the peritoneum. A 66-year-old female with history of Stage 1b endometrial adenocarcinoma was found to have rectal adenocarcinoma on surveillance colonoscopy. Cross-sectional imaging demonstrated a vaginal cuff mass with bladder wall thickening and unilateral hydronephrosis. A bladder mass was identified and partially resected on cystoscopy; pathology was indicative of urothelial carcinoma. The final surgical specimen demonstrated endometrial cancer as the primary culprit in all three organs, confirmed by additional immunohistochemical staining of the previous bladder resection specimen. The rarity of hollow organ involvement in locoregional endometrial cancer recurrence can engender misdiagnosis, potentially leading to discordant treatment and suboptimal outcomes. A high index of suspicion in conjunction with multidisciplinary discussion may have prompted additional immunohistochemical testing to obtain the correct diagnosis earlier in the patient's clinical course.
