Furniture components can cause contact allergies. In the last years several cases of eczema after sofa contact have been reported. Typically the skin lesions develop on the back, the buttocks, the dorsal aspects of the thighs and arms and are often very resistant to topical corticoid therapy. Dimethylfumarate (DMF) is postulated to be the causative agent for this Type IV hypersensitivity reaction. DMF is an antimicrobial substance, which is used in asian upholstered furniture industry amongst others. We report the case of a 65-year old patient with generalised severely itching maculopapular, partly eczematous skin lesions on the buttocks, back, abdomen and arms. The resistance to therapy, several relapses after discharge from hospital as well as the detailed history lead us to the tentative diagnosis. The sofa dermatitis was proven by positive patch testing with furniture material and dimethylfumarate.
家具部件会引起接触过敏。近年来，有几起因接触沙发而导致湿疹的病例报告。典型的皮肤损伤发生在背部、臀部、大腿和手臂的背面，并且通常对局部皮质类固醇治疗非常有抵抗力。二甲基富马酸（DMF）被认为是这种 IV 型超敏反应的致病因素。DMF 是一种抗菌物质，除其他外，还用于亚洲软垫家具行业。我们报告了一例 65 岁患者的病例，其臀部、背部、腹部和手臂上出现广泛严重瘙痒的斑丘疹、部分湿疹样皮肤损伤。对治疗的抵抗力、出院后多次复发以及详细的病史使我们做出了暂定诊断。通过对家具材料和二甲基富马酸进行斑贴试验，证实了沙发皮炎。
