Abstract

Amylase-producing multiple myeloma is a rare disorder and has poor prognosis. Its characteristics are elevation of salivary type amylase, extensive extramedullary spread, extensive bone destruction, shorter survival time, and abnormal karyotype. Recently, we have experienced a case of amylase-producing IgG kappa type multiple myeloma in a 63-year-old woman. On admission, serum and urine amylase was 8,450U/L and 169,710U/L, 85% and 86% of which was determined to be the salivary type, respectively. The other cause of hyperamylasemia had not been detected. The presence of immunoglobulin and amylase in the myeloma cells was demonstrated immunohistochemically. Bone marrow aspiration smear revealed 59.1% plasma cells. The
cytogenetic study of bone marrow cell showed normal karyotype. The patient died 3 months after chemotherapy with melphalan and prednisolone.
