(a) CT scan without contrast revealed large right complex adnexal mass (red arrow), with the attached cyst (yellow arrow) and the left ovary (blue arrow). The blue arrow shows the left ovary. (b) Gross photo shows ruptured fallopian tube with placental-like tissue and adjacent cyst. (c) Hematoxylin and eosin (H&E) histopathology examination demonstrates dilated villi with cistern and circumferential trophoblastic proliferation (H&E; 1x). (d) Vascular invasion (H&E; 1x).

The patient underwent an immediate computerized tomography (CT scan) to assess the extent of the disease which showed large right adnexal mass with abdominal ascites and numerous peritoneal lesions (Figure 1(a)). The attached hemorrhagic and ruptured fallopian tube (3 x 2.7 cm) exhibits multiple small vesicles and fragments of placental-like tissue in the vicinity of the perforated areas (Figure 1(b)). Circumferential trophoblastic proliferation with cistern formation was readily appreciated (Figure 1(c)). Besides, cytological atypia, mitosis, apoptotic debris, and vascular invasion were identified (Figure 1(d)).
