case_images: The exam also evidenced an increase in the duration of the QRS complexes (0.1 sec.) with morphology within the normal values, suggestive of an advanced 2nd-degree AV block (Wagner, 2009) (Fig. 2).
case_images: (A) A nodular lymphoid infiltrate in the hepatic parenchyma (H&E, X20). (B) A nodular lymphoid infiltrate between the myocardial fibers (H&E, X20). (C) Lymphocytic infiltration in the connective tissue of the pericardium (H&E, X20).

case_images: A subsequent histological examination confirmed the diagnosis of hepatic lymphoma (Fig. 3A). Furthermore, lymphocytic infiltrations were also found within the pericardium, as per non-specific pericarditis (Fig. 3B, C).
