Plasma cell disorders Flashcards
what is paraproteinaemia?
presence of a monoclonal immunoglobulin band in the serum
what is multiple myeloma?
a neoplastic disease characterised by plasma cell accumulation in the bone marrow + presence of monoclonal protein in serum or urine + related tissue damage in symptomatic patients
what is the peak incidence of multiple myeloma?
65-70 years old
Almost all cases of myeloma develop from a pre-existing monoclonal gammopathy of undetermined significance (MGUS). T or F.
True
what is smouldering myeloma?
asymptomatic version of multiple myeloma; similar lab findings nut not organ or tissue damage
how is symptomatic myeloma diagnosed?
if there is

- increased clonal plasma cells in the bone marrow
- disease-related organ or tissue impairment
what are the features of myeloma-associated tissue damage?
- hypercalcaemia
- renal impairment
- anaemia
- bone disease
CRAB

- bone pain
- features of anaemia
- recurrent infections
- features of renal failure or hypercalcemia
