case_images: IU/L (normal range: <2), LDH: 527 U/L (normal range: 105-333)) with normal AFP level (2.34 ng/mL (normal range: 0-40). In computed tomography (CT) imaging, a 40 mm retrovesical mass was detected (Figure 1).
case_images: Uterine-like structure located at the dome of the bladder, no ovaries were seen upon further dissection.

case_images: Upon entering the abdomen through the midline laparotomy incision, a pear-shaped structure was encountered on the dome of the bladder (Figure 2) which was resected.
case_images: Necrotic tissue behind the bladder at the level of the bladder neck which was scraped off the adjoining structure with wire loop.

case_images: We continued the dissection behind the bladder, and we encountered grayish necrotic tissue which we had to scrape off from the joining structures (Figure 3).
case_images: Endometrial tissue (a) and necrotic material with a free-floating cluster of malignant cells (b).

case_images: All resected retroperitoneal lymph nodes were benign reactive nodes (53 in total), and the retrovesical tissue was a necrotic material with rare small free-floating clusters of atypical cells (less than 1% of the mass) compatible with minimal residual tumor (Figure 4).
