A repeat CT in addition to Magnetic Resonance Imaging (MRI) and Magnetic Resonance Cholangiopancreatography (MRCP) revealed only marginal enlargement in the pancreatic cystic lesion, but now there were also multiple lesions in the liver ranging from a few milimetres to 2.5 cm in diameter (Figure 1).
Histological section of the liver biopsy that demonstrates infiltration by a giant cell carcinoma with a diffuse growth pattern. The neoplastic cells line also pseudospaces due to lack of cohesiveness. (H & E counterstain, magnification x200).

The growth pattern was diffuse with pseudospaces, and the stroma was loose and abundant with inflammatory infiltrates (Figures 2(a) and 2(b)).
Representative immunohistochemical results. Cytokeratin 7 (a) and cytokeratin 19 (b). DAB immunohistochemistry performed by an indirect streptavidin-biotin-peroxidase method on paraffin section counterstained with haematoxylin. (magnification x400).

The neoplastic cells showed cytokeratin 7 (Figure 3(a)) and cytokeratin 19 (Figure 3(b)) immunopositivity.
