3. Multiple Myeloma Flashcards
Malignant proliferation of plasma cells that infiltrate bone marrow
Multiple Myeloma
Kahler’s disease aka
Multiple Myeloma
mc primary malignant bone tumor
Multiple Myeloma
- Anemia due to diseased hematopoietic tissue by
proliferating plasma cells - Osteopenia in bones with red bone marrow
- Abnormal serum and urinary proteins
- Renal disease
Multiple Myeloma
cardinal symptom of Multiple Myeloma
Pain (aggravated by activity)
in multiple myeloma, slight strain may produce
pathologic
compression fractures that may result in
paraplegia
- Weight loss
- Cachexia
- Anemia
- Unexplained Osteoporosis
Multiple Myeloma
m/c affected bones in Multiple Myeloma
Spine and other red marrow containing bones such as flat bones
- “M spike” in 90% of patients
- IgG myeloma 50%
- Bence Jones proteinuria
Multiple Myeloma
For multiple myeloma we aspirate and biopsy bone marrow
of
sternum and ilium
reflects microscopic
appearance of nuclei in multiple myeloma
Round cell disorder
Multiple, permeative lesions, that are filled by gelatinous,
red, soft masses of neoplastic plasma cells, that are surrounded by areas of increased
osteoclastic activity
Multiple myeloma patients usually die of
pneumonia and
respiratory failure
(possibly renal failure)
May erode into adjacent bony structures and is m/c seen in nasopharynx
Extraosseous Plasmacytoma
are bones scans helpful for multiple myeloma?
NO
