The patient underwent an R) portal vein embolization and subsequently an extended R) hepatectomy.

The large tan, nodular lesion measured 95x90x80mm with a large area of central necrosis.

The immunohistological showed positive staining for CEA, CK7 and GATA3. Negative staining for CK20, ER, PR and Hep Par1. This staining pattern was similar to the breast carcinoma obtained from a wide local excision 1 year ago.

This confirmed the diagnosis of metastatic breast ductal carcinoma.
