If you mean a diagonal line or crease running across the earlobe, it is commonly called Frank’s sign or a diagonal earlobe crease.
- It has been associated in research with coronary artery disease and atherosclerosis. A 2025 meta-analysis found that people with the crease were more likely to have coronary artery disease. PubMed
- But it is not a diagnosis. Other systematic reviews have found its ability to predict coronary disease is too limited for the crease alone to guide medical decisions. PubMed Central (PMC)+1
- The crease also becomes more common with aging, so seeing it in an older person does not necessarily mean they have heart disease. PubMed Central (PMC)
So, if you have this mark, think of it as a possible clue—not a warning that you definitely have blocked arteries. It is more useful to check the real cardiovascular risk factors: blood pressure, cholesterol, diabetes, smoking, weight, physical activity, and symptoms.
If by “particular mark” you mean a different spot, lump, discoloration, or line on the ear, tell me what it looks like (or upload a photo), and I can explain what that specific mark may mean.
