Background: Skin tags (STs) are benign skin lesions. Their definite etiology remains unknown. We aim to examine the association of obesity, diabetes mellitus, hyperlipidemia, thyroid abnormalities, acanthosis nigricans, and multiple STs in a Greek primary population. Methods: Phototype and body weight were recorded. Fasting serum blood samples were analyzed for cholesterol, low-density lipoprotein, high-density lipoprotein, triglycerides, glucose, and thyroid-stimulating hormone. Univariate ordinal logistic regression multivariate analysis was performed. Results: The univariate analysis showed that patients who were overweight with Fitzpatrick Skin Type III, acanthosis nigricans, and hypothyroidism were more likely to present with multiple skin tags as compared with patients at a normal weight with Skin Type I. Statistically significant associations were also found with the presence of cholesterol and triglycerides. In the multivariate analysis, a significant association between hypercholesterolemia and STs was demonstrated. Those with skin tags were more likely to have hypothyroidism. Conclusion: STs are often associated with obesity. An association between lipid profile and STs has been reported. Multiple STs have been independently associated with acanthosis nigricans. Although a possible relationship between STs and thyroid disease has not yet been proved, our review reveals a possible trend. Future investigations with larger sample sizes might clarify the association between skin tags and hypothyroidism.
