Background: Acrochordons (known as skin tags) are benign skin tumors. A few studies with contradictory results have been reported regarding the abnormalities of carbohydrate and/or lipid metabolisms in patients with skin tags.
Aim: The aim of this study is to determine if the presence of acrochordons could be a marker of Metabolic syndrome by comparing with a control group.
Subjects and methods: A total of 110 patients having two or more acrochordons and age- and gender-matched 110 controls were included in the study. Localization, size and the total number of acrochordons were recorded in the patient group. Age, sex, body mass index (BMI), waist circumference, smoking status, fasting plasma glucose (FPG), impaired glucose tolerance (IGT) test, insulin resistance, serum lipids and liver enzyme levels were estimated in cases and controls. Arterial blood pressures were measured in two groups.
Results: A total of 58 patients and 12 controls were diagnosed with overt diabetes mellitus (DM). 15% (16/110) of patients and 8% (9/110) of controls had an IGT test. The difference was statistically significant for the diagnosis of DM and not significant for the IGT. The mean levels of FPG, BMI, insulin resistance, total cholesterol, low-density lipoprotein cholesterol and triglyceride were significantly higher in patients than those in controls. Serum levels of high-density lipoprotein were less in patients. Patients with acrochordons had higher systolic and diastolic blood pressures than controls.
Conclusion: Acrochordons may represent a cutaneous sign for Metabolic syndrome. Changing the life-style of these patients may have a beneficial role.
