Question

which of the following cell types are found with multiple myeloma
rouleaux formation
acanthocytes
schistocytes
spherocytes

Explanation:

Multiple Myeloma is a plasma cell disorder. Rouleaux formation (stacking of red blood cells) is associated with increased serum protein (like in Multiple Myeloma due to abnormal immunoglobulins). Acanthocytes are related to lipid disorders, Schistocytes to microangiopathic hemolytic anemia, and Spherocytes to hereditary spherocytosis or immune hemolytic anemia. So Rouleaux formation is linked to Multiple Myeloma.

Answer:

A. Rouleaux formation
