Other Known Aliases – Heinz-Ehrlich Bodies, Ehrlich Inner Body
Definition – Deep purple small irregular bodies in red cells stained with crystal violet which represents denatured hemoglobin due to oxidative damage.
Clinical Significance – Seen in conditions in with high oxidative stress such as:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency
- Alpha thalassemia
- NADPH deficiency
- Chronic liver disease
History – Given to Dr. Robert Heinz (1865-1924), who was a German physician and pharmacologist who first reported these findings 1890 in the blood of guinea pigs that had treated with acetylphenylhydrazine. Dr. Paul Ehrlich (1854-1915), was a German bacteriologist and immunologist, is also credited with this, but did not publish it formally (as best I can tell)
