Amylase-producing Bence Jones multiple myeloma with pancreatitis-like symptoms

Acta Haematol. 1993;90(2):99-101. doi: 10.1159/000204384.

Abstract

Amylase-producing tumors are mainly adenocarcinomas and, in rare instances, multiple myelomas. We describe here a first case of amylase-producing Bence Jones type myeloma with pancreatitis-like symptoms and the second in a Caucasian patient. The finding of salivary-type hyperamylasemia in a 72-year-old female with a possible pancreatitis made us suspect the diagnosis. Amylase production was observed in bone marrow cultures in which 96% of cellularity was composed of plasmablasts. Serum amylase level decreased when chemotherapy was given.
