Waldenstrom's Macroglobulinemia


- Mutation: MYD88 mutation.
- B-cell malignancy
- Cell Types affected:
- Lymphocytes, plasma cells, mast cells
- Other Name:
- Lymphoplasmacytic Lymphoma
- Definition:
- Elevated IgM (highest molecular weight).
- Serum M component
- IgM > 30 g/L
- Large IgM size → minimal renal excretion
- Only ~20% patients excrete light chains
- Clinical:
- Hyperviscosity syndrome
- d/t rouleaux formation
- Thick blood → HTN, visual issues, Nose bleed
- Peripheral neuropathy
- Due to myelin-associated glycoprotein
- Causes demyelination

- Bone marrow
- >10% infiltration with Lymphoplasmacytic cells
- Mnemonic: Wardern → Nishara
- Always in Middle of Girls (Myd 88)
- High BP (HTN)
- Masturbates (Mastocytosis)

Interpupillary distance → normal
