AbstractPathergy phenomenon is a non-specific tissue hyperreactivity reaction due to trauma and is a minor diagnostic criterion of Behcet's disease. In this study, 100 patients with a suspicion of Behcet's disease who were referred to Cerrahpasa Medical Faculty Dermatology department between 01.11.2014 and 31.01.2015 are included. Skin pathergy tests were applied to all the patients and results were evaluated by two dermatologists separately at 48th hour, each with naked eye and with dermatoscopy. Test results were scored on a scale of 0-6. At the end of the study, score results of naked eye and dermatoscopy for doctor number 1 were statistically similar. Same results applied for doctor number 2. However, naked eye results of doctor number 1 and 2 for the same patients were significantly different from each other (p 0.0372) and with dermatoscopy examination this difference was eliminated (p > 0.05). This study revealed that naked eye evaluation of pathergy test results can yield different results among different interpreters. Use of dermatoscopy during the evaluation process decreases interobserver variation and subjectivity of the test.
