Abstract

Background: In Malaysia, occupational allergic contact dermatitis (ACD) is often under-reported. This case report describes a chemical engineer who developed possible ACD, likely due to workplace allergen exposure.

Case presentation: He presented with a 4-month history of intensely itchy rashes on both hands, which improved during work breaks. A dermatological examination revealed lichenified, pruritic papules with well-defined borders on the palmar surfaces of both hands. A skin patch test identified reactions to five allergens, including 'fragrance mix,' 'methyldibromo glutaronitrile,' 'clioquinol,' 'epoxy resin,' and 'textile dye mix.' However, among these, only 'bisphenol A diglycidyl ether,' a component of 'epoxy resin,' was listed in the safety data sheet as a confirmed occupational exposure. In accordance with local regulations, this case was reported as 'occupational dermatitis' to the Department of Occupational Safety and Health. The patient was prescribed symptomatic topical treatments, including emollients and topical corticosteroids. Additionally, he was advised to switch to hypoallergenic products. On follow-up, his chronic inflammatory skin lesions showed improvement.

Conclusions: Thorough occupational history-taking and patch testing are essential for diagnosing ACD. Personalized health education and regular follow-ups, is crucial in monitoring lesion resolution and evaluating the effectiveness of preventive measures in workplace settings.

职业性过敏性接触性皮炎诊断的挑战:1例报告。
背景:在马来西亚,职业性过敏性接触性皮炎(ACD)经常被低估。本病例报告描述了一名化学工程师,他可能由于工作场所过敏原暴露而患上了ACD。病例介绍:他有4个月的双手强烈发痒的皮疹病史,在工作休息时有所改善。皮肤病学检查显示双手手掌表面有边界明确的地衣化、瘙痒性丘疹。一项皮肤贴片试验确定了对五种过敏原的反应,包括“香料混合物”、“甲基二溴戊二腈”、“氯喹诺”、“环氧树脂”和“纺织染料混合物”。然而,在这些物质中,只有“双酚A二缩水甘油醚”,一种“环氧树脂”的成分,被列为安全数据表中确认的职业暴露。根据当地规定,这一病例作为“职业性皮炎”报告给了职业安全与健康司。患者给予对症局部治疗,包括润肤剂和局部皮质类固醇。此外,医生建议他改用低过敏性产品。在随访中,他的慢性炎症性皮肤病变有所改善。结论:全面的职业病史和斑贴试验是诊断ACD的必要条件。个性化健康教育和定期随访对于监测病变消退和评估工作场所预防措施的有效性至关重要。
