Basophilic stippling is often associated with:

• A. Autoimmune disease
• B. Anemia
• C. Lead poisoning
• D. Neoplasia

Answer: (C)

Basophilic stippling is a microscope finding where red blood cells show small blue dots from retained ribosomal RNA. This occurs when erythropoiesis is disrupted, such as when a toxin interferes with heme synthesis. Lead poisoning is classically linked to basophilic stippling because lead inhibits enzymes like ALA dehydratase and ferrochelatase, causing accumulation of ribosomal RNA that appears as stippling on a blood smear. While stippling can appear in some other anemias, the association most fitting this list is lead poisoning, making it the best answer. Autoimmune disease and neoplasia do not typically produce basophilic stippling, and while anemia describes a condition, it does not point to the specific cellular change seen here.
