case_images: MRI findings. a, b T2-weighted images. c T1-weighted images. The cystic mass, measuring approximately 7 cm, extended continuously from the anterior wall of the lower uterine segment into the pelvic cavity (yellow arrows).

case_images: Fig. 1; for all online suppl. material, see https://doi.org/10.1159/000539428). The mass showed subacute hemorrhagic contents, demonstrating high signal intensity on both T2-weighted images (T2WI) and T1-weighted images (T1WI) (shown in Fig. 1a-c).
case_images: Laparoscopic (a-c) and hysteroscopic (d) findings. Cystic mass containing old hemorrhagic material was observed growing in the left paracervical retroperitoneal space. The light from the hysteroscope could be observed from the abdominal cavity (blue arrow). Cervical cavity (white arrow). A fistula from the cervical cavity into a cystic mass (yellow arrows).

case_images: Intraoperative examination revealed a cystic mass containing old hemorrhagic material in the left paracervical retroperitoneal space (shown in Fig. 2a-c). Fig. 2d and online suppl. Fig. 2a, b).
case_images: a Macroscopic findings of the resected specimen. Dark red mottled lesions involving the entire thickness of the myometrium and fistula to a cystic mass were observed (yellow arrows). b Hematoxylin and eosin staining showed medium-sized tumor cells with distinct nucleoli and round nuclei proliferated, forming sheets, and nests with geographic necrosis. c Immunohistochemical staining for p63. The tumor cells were positive for p63.

case_images: Fig. 3). Pathologically, dark red, mottled lesions involving the entire thickness of the myometrium were observed in the lower uterine segment, in continuity with cystic lesions protruding from the uterine serosa (shown in Fig. 3a). AE1/AE3, p40, and p63. A diagnosis of ETT was made based on these findings (shown in Fig. 3b, c).
