Lack of association between skin tags and colon polyps in a primary care setting.
Cutaneous skin tags (acrochordons) have recently been proposed as markers for adenomatous polyps of the colon among symptomatic patients referred for colonoscopy. To ascertain the utility of skin tags as a predictor of colonic polyps in a primary care setting, 492 patients, with a mean age of 58 +/- 13.3 years (241 with signs or symptoms and 251 for screening), were evaluated for the presence of skin tags and then examined using a 60-cm fiberoptic sigmoidoscope by an examiner "blinded" to the skin findings. Among patients with skin tags, 23 (10.2%) of 226 had polyps, whereas among patients without skin tags, 20 (7.5%) of 266 had polyps. The predictive value of the presence of a skin tag was 10.2%. Contrary to studies done in more selected populations with a higher prevalence of adenomatous polyps, the results using a 60-cm flexible sigmoidoscope in a primary care population suggest that cutaneous skin tags are not a marker for adenomatous polyps of the colon.
