In HE-stained sections, hepatic macrovacuolar lipidosis in the liver and macrophages loaded with brownish pigments are evident. HgSe crystals can be observed in the liver (hepatocytes and Kuppfer cells) and lymph nodes (sinusal macrophages) both with the automethallographic staining (black arrows) and ESEM pictures (white arrows). In Fig. G also follicular lymphoid depletion is prominent (*).
