摘要: A case of “non-secretory” multiple myeloma is described. The diagnosis was based on the clinical picture, typical radiological findings, and infiltration bone marrow by cells which showed specific immuno-fluorescence staining mainly with antisera for IgM kappa light chains. An attempt made to explain absence pathological proteins in serum, ultrastructural findings cells, “buddings” cell membranes containing endoplasmic reticulum cytoplasmic material. It suggested that type possess a normal excretory mechanism, but are prevented be secreted serum being surrounded portions membrane.
