Histopathologic examination showed acanthosis, widespread spongiosis, diffuse parakeratosis, and a superficial perivascular lymphocytic infiltrate (Figure 3). Investigations revealed a glucagon level of 1140 pg/mL (reference range 50-200 pg/mL) (to convert picograms to nanograms, multiply by 1.0). Computerized tomography (CT) of the pancreas revealed a 98 × 67-mm epigastric mass centered on the pancreatic head and neck.
