Shiitake Dermatitis is a skin eruption that resembles whiplash marks and occurs after consumption of raw shiitake mushrooms. It is caused by a toxic reaction to lentinan, a thermolabil polysaccharide which decomposes upon heating. We report the second case of this dermatitis in Brazil. A 25-year-old man presented with linearly arranged erythematous, pruritic papules on the trunk and limbs, after ingestion of a salad containing raw shiitake mushrooms. The eruption was self-limited, resolving within 10 days of onset. The recognition of this entity gains importance due to the increased consumption of shiitake mushrooms in occidental countries.
香菇皮炎是一种皮疹，类似鞭打伤痕迹，在食用生香菇后出现。它是由对香菇多糖的毒性反应引起的，香菇多糖是一种热不稳定的多糖，加热后会分解。我们报告了巴西第二例这种皮炎病例。一名25岁男子在食用了一份含有生香菇的沙拉后，躯干和四肢出现了呈线状排列的红斑、瘙痒性丘疹。皮疹为自限性，发病后10天内消退。由于西方国家香菇消费量的增加，认识这种疾病变得更加重要。
