Introduction: Seborrheic keratosis (SK) is a benign tumor of the epidermis, its development is associated with various hypotheses, but none came out as the main culprit. A few study results regarding the oxidative stress strongly associated with skin tumors have been reported. Superoxide dismutase (SOD) is a potent protective enzymatic antioxidant. Malondialdehyde (MDA) is the end product of lipid peroxidation produced by free radicals in the body. Increased levels of MDA usually accompany low levels of antioxidants.

Methods: This study was an observational analytic study with a cross-sectional method involving 42 seborrheic keratosis subjects based on inclusion and exclusion criteria. We recorded the gender, age, family history, and occupation of the subjects. Diagnosis of seborrheic keratosis was made based on history taking and clinical examination—measurement of SOD level by ELISA method and MDA levels by TBARS method. The Spearman correlation test was measured and was considered significant if the p-value was <0.05.

Results: Seborrheic keratosis was more common in females (92.9%), with the most common age group being 40 ̶ 50 years old (57.1%), had a family history of SK (26.2%), and worked in agriculture, forestry, and fisheries (26.2%). The average blood plasma SOD level was 1.68 mmol/L, and the blood plasma MDA level was 181.19 U/L. The correlation coefficient between blood plasma SOD levels and blood plasma MDA levels was -0.393, with a significant value of p=0.01. This study showed that the lower the SOD level, the higher the MDA level in the blood plasma of seborrheic keratosis.

Conclusion: There is a significant correlation between SOD and MDA levels in the blood plasma of seborrheic keratosis subjects.
