question: Can multiple myeloma patients develop hyperviscosity syndrome?
answer: Yes, multiple myeloma patients can develop hyperviscosity syndrome. Multiple myeloma is a neoplastic plasma-cell disorder resulting from malignant plasma cells in the bone marrow. It can cause a hyperviscosity syndrome secondary to the paraproteinaemia associated with the disease. The increased hyperviscosity can lead to retinal vein occlusions and other ocular problems.
