Rouleaux formation on a smear is commonly associated with which condition?

Rouleaux form when red blood cells stack like coins because there is a high concentration of plasma proteins, especially immunoglobulins, which reduces the repulsive charge between cells and promotes aggregation. In multiple myeloma, a monoclonal gammopathy leads to a large excess of a single immunoglobulin, dramatically increasing plasma protein levels and making rouleaux formation on a smear a classic clue. The other conditions listed don’t typically produce this hyperproteinemia pattern, so they aren’t the usual associations for rouleaux.
