The patient went on to have a resection. 

Histology: 

Sections of all three specimens show predominantly recent hemorrhage, associated with focal metastatic carcinoma, consistent with metastatic choriocarcinoma. Immunohistochemical studies show that the neoplastic cells are immunopositive for HCG and are immunonegative for alpha-fetoprotein.

Note: Unfortunately, this is an older case and I have no further information or imaging.
