ABSTRACT
OBJECTIVE: Sulfur mustard (SM) exposure intensely causes lesions that range in severity from mild erythema to blister formation and necrosis. This review will discuss acute and long-term skin consequences due to exposure to SM and different kinds of medical prophylaxis and therapeutics against SM-induced skin lesions. METHODS: Literature survey of medical case reports, clinical studies, and original articles was performed using PubMed, Medline, and the Cochrane Database (1917-2011 March). Key words included sulfur mustard, skin, toxicity, pathogenesis, cancer, treatment. RESULTS: SM-induced damage to the skin is characterized by edema, inflammation, and cell death mainly of the basal keratinocyte layer, with varying immunological and pathological changes in the acute phase. Also, xerosis, hypo or hyper pigmentation, scars, and rarely, skin cancers are long-term cutaneous effects. So far,the combination therapy of topical drugs and oral antihistamines, also iodine and antitumor necrosis factor alpha antibodies, are effective remedies in the treatment of skin lesions. CONCLUSION: The requirement for preparedness in the dermatological community concerning SM exposure is underlined. Novel treatments for prevention and therapeutics against SM toxicity and carcinogenicity are reviewed.

Sulfur mustard (SM) is a potent chemical warfare agent that was widely used during the First World War and the Iran-Iraq conflict. This vesicant agent causes several acute and chronic effects on the skin, eye, and respiratory system. We report the case of a 41-year-old man who was injured with SM in Iraq chemical attack in 1988. After exposure, he developed severe skin blisters on his upper trunk, dorsum of hands, and genitalia. Based on several clinical observations, such as atrophy, pigmentation, and vascular changes on genitalia with relevant findings in histopathological studies, persistent pigmentation, and damaged skin appendix in hand lesions, a diagnosis of "SM-induced poikiloderma" was postulated. The absence of any complication on the palmar aspect of hands is another remarkable finding in presented case, which suggests a plausible role of the palms as a vector for transporting SM to other sites of the skin.
