Supplementary Material for: Palmar Telangiectasias: A Cutaneous Sign for Smoking

Background: Telangiectasias are permanent dilations of blood capillaries which appear in a variety of medical conditions. Cutaneous palmar telangiectasias have been postulated to be associated with smoking. Objective: To determine whether a significant correlation exists between palmar telangiectasias and smoking habits. Patients and Methods: A total of 124 volunteers participated in this observational study by allowing physical evaluation of their palms and by completing a questionnaire. Results: Palmar telangiectasias were found to be associated with current or past smoking. Neither age nor gender was found to be a co-contributor. Discussion: Palmar telangiectasias were found to constitute highly specific and sensitive markers for prolonged smoking.
