Which statement best describes the relationship between burr cells and their associated conditions?

• A. Burr cells are exclusive to hemolytic anemias
• B. Burr cells are commonly seen in uremia and PK deficiency
• C. Burr cells indicate severe iron overload
• D. Burr cells are diagnostic of lymphoma

Answer: (B)

Burr cells, or echinocytes, are red blood cells with evenly spaced, short membrane projections. They arise when the RBC membrane or cytoskeleton is altered, which can happen in certain systemic conditions. In uremia, buildup of toxins disrupts membrane integrity and energy balance, causing the characteristic spiculated appearance. Pyruvate kinase deficiency lowers ATP in red cells, weakening the membrane skeleton and producing burr cells as well. Because these conditions are classically linked to burr cell formation, this description best matches the relationship between burr cells and their associated conditions. They are not exclusive to a single disease, and they are not diagnostic of iron overload or lymphoma.
