Résumé
Chemical gas weapons especially nitrogen mustard which was used in Iraq-Iran war against Iranian troops have several harmful effects on skin. Some other chemical agents also can cause acne form lesions on skin. The purpose of this study was to compare the incidence of acneform in previously chemically damaged soldiers and non chemically damaged persons. In this descriptive and analytical study, 180 chemically damaged soldiers, who have been referred to dermatology clinic between 2000- 2004, and forty non-chemically damaged people, were chosen randomly and examined for acneform lesions. SPSS software was used for statistic analysis of the data. The mean age of the experimental group was 37.5 +/- 5.2 and that of the control group was 38.7 +/- 5.9 years. The mean percentage of chemical damage in cases was 31 percent and the time after the chemical damage was 15.2 +/- 1.1 years. Ninety seven cases [53.9 percent] of the subjects and 19 people [47.5 percent] of the control group had some degree of acne. No significant correlation was found in incidence, degree of lesions, site of lesions and age of subjects between two groups. No significant correlation was noted between percentage of chemical damage and incidence and degree of lesions in case group. Incidence of acneform lesions among previously chemically injured peoples was not higher than the normal cases
