Sulfur mustard (2,2-dichlorodiethyl sulfide, SM) is one of the vesicant classes of chemical warfare agents that causes blistering in the skin and mucous membranes, where it can have lingering long-term effects for up to ten years (1). SM was employed extensively by the Iraqi army against not only Iranian soldiers but also civilians between 1983 and 1988, resulting in over 100,000 chemical casualties. Approximately 45,000 victims are still suffering from long-term effects of exposure (2,3). More than 90% of the patients exposed to SM exhibit various cutaneous lesions in the affected area. The human skin can absorb approximately 20% of the SM through exposure. Up to 70% of the chemical is concentrated in the epidermis and the remainder in the basement membrane and in the dermis (4).Sulfur mustard exists in different physical states. The liquid form of SM evaporates slowly in cold weather and can penetrate through the clothing, thereby increasing exposure. However, the gas form readily diffuses in the air and it can be inhaled, leading to systemic absorption. In addition, warm temperatures are ideal conditions that liquid SM present in the clothing of the exposed individual could be converted to gas form. SM-induced clinical cutaneous symptoms include itching and burning. Other clinical findings include erythema or painless sunburn, bulla, hypo- and hyper pigmentation in both exposed and unexposed areas (5,6) The mechanism and biochemical cascade of SM-induced cutaneous manifestations are not completely understood but several published pathways support many of the know facts. Our current understanding fails to explain the time interval between the acute chemical exposure and the late-onset and delayed tissue damage (7,8). The aim of this article is to review the acute and long-term cutaneous findings resulting from SM exposure. Also, cellular and molecular mechanism involved in SM-induced skin pathology have been discussed.
Background: Albinos in Africa are at constant risk of developing skin cancer due to the damage caused by ultra-violet exposure. This study identifies the common skin conditions among albinos in Kenya as a country located along the equator. Methods: In this descriptive study on albino patients who were admitted to Mbagathi District Hospital in Nairobi, Kenya the census method was used for sampling and a total of 151 albinos were registered. All necessary data including age, gender, type, site and the number of skin lesions were recorded. Suspected patients with malignant and premalignant lesions were studied individually through skin biopsy and histopathological investigation. Finally, the collected data were analyzed using SPSS software. Results: Albinos with serious skin lesions were 121(80%) patients. Females were 64 (52.9%). The frequency of the following premalignant and malignant skin lesions including actinic-cheilitis, solar elastosis, actinic keratosis (AK), basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) were 17.88%, 11.92%, 37.08%, 7.94% and 5.29%, respectively. Hands (20.52%), face (19.20%), head (18.18%), shoulder (14.56%) and neck (7.94%) were the most affected areas by malignant and premalignant lesions. Conclusions: BCC was the most common type of cutaneous malignancy on the face and shoulders while AK was the most common cutaneous pre-malignancy on the hands and face in albinos in Kenya. Therefore, appropriate physical protection, avoiding any trauma when carrying sharp, heavy or rough instruments by the shoulder and hands, and finally urgent and quality treatment for any lesion even a small erosion and ulcer, especially on exposed areas in albinos, are recommended.
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.
Mustard induced dermaltologic lesions were more common and specific than (NA) skin injuries. (NA) cause few psychocutaneous disorders like acne and seborrheic dermatitis in addition to psychological stress disorders.
Background:The relationship between compromised immune system and the development of malignancy, generalized dermatitis, and infection after sulfur mustard gas exposure has been established. Main observation:We introduce a 58-year-old man with an abrupt, de novo and erythrodermic eruption in 2002 that was previously exposed to sulfur mustard during the Iran -Iraq war in 1987. Six weeks after the onset of diffuse eruption, he developed papules on the glans penis and generalized dermatophytosis. A biopsy of his eruption was consistent with cutaneous T-cell lymphoma/Sézary syndrome. A complete blood count demonstrated leukocytosis, eosinophilia and atypical lymphocytosis. Subsequently, Sézary syndrome was confirmed and T-cell count with increased CD4/CD8 in flow cytometry. The biopsy of his penile papules was consistent with Kaposi's sarcoma. Conclusion:These findings suggest a causative relationship between sulfur mustard gas exposure, cutaneous T cell lymphoma and immune compromised state with opportunistic infections. (J Dermatol Case Rep. 2012; 6(3): 86-89) Sézary syndrome, Kaposi sarcoma and generalized dermatophytosis 15 years after sulfur mustard gas exposure IntroductionCutaneous T-cell lymphoma (CTCL) comprises a group of clinicopathologic entities that are neoplastic proliferation of T lymphocytes that home to the skin. Eventually the T-cells may lose their dependence on an epidermal environment for growth, and spread to the dermis, lymph nodes, blood, and viscera. 1,2The cutaneous lesions evolve from patches to plaque and tumors (mycosis fungoides), and Sézary syndrome, where the neoplastic cells circulate in the peripheral blood. The patients present with generalized exfoliation erythroderma, intense pruritus, peripheral lymphadenophaty, and abnormal hyperchromatic mononuclear cells in the skin and peripheral blood. Decreased T-cell function may lead to subsequent immune compromised status and is followed by infection. 4 Kaposi sarcoma (KS) is a vascular tumor of intermediate malignancy, histologically characterized by proliferation of lymphatic and/or vascular endothelial cells caused by the Kaposi's sarcoma-associated herpesvirus (KSHV), human herpesvirus 8. KS is a systemic disease, which can present with cutaneous lesions with or without internal involvement. Four subtypes have been described: Classic KS, affecting middle aged men of Mediterranean descent, African endemic KS, KS in iatrogenically immunosuppressed patients, and AIDS-related KS. 5Sulfur mustard gas is a potent alkylating agent that has a long history of use as a chemical warfare agent, including recent use by Iraq against Iranian soldiers and civilians. The organs most commonly affected by sulfur mustard gas (SM) are skin, eyes, and airways. Skin lesions are seen in more than 90% of the patients exposed to SM. Although the acute DOI: http://dx.doi.org/10.3315/jdcr.2012.1109 86 systemic and cutaneous effects of SM are well known, few investigations have focused on reporting the long-term carcinogenic effects. 6,7Case Repor...
