Massive hyperhaptoglobinaemia (more than 8 g/l) was seen in a 58-year-old female patient with plasmocytoma and amyloidosis. In the literature, hyperhaptoglobinaemias of up to the three- or fourfold of the upper normal limit have been reported. However, they are very rare. In the present case it might be speculated that extrahepatic formation of haptoglobin occurred within paraproteinaemia of plasmocytoma.
