Ingestion of raw or undercooked shiitake mushrooms is associated with a distinctive flagellate erythema. We describe a 61-year-old Caucasian man who presented with a pruritic, erythematous eruption of multiple linear streaks on the trunk and extremities starting 1 day after eating raw shiitake mushrooms. His symptoms and skin lesions resolved with minimal hyperpigmentation within approximately 1 week after treating with topical steroids and oral antihistamines. Skin biopsy showed non-specific findings, including a sparse perivascular and interstitial dermatitis as well as focal vacuolar interface changes. Our case illustrates that this condition is a visibly striking dermatitis with a self-limited course. The pathomechanism of the skin eruption remains unclear.
食用生的或未煮熟的香菇会引发一种独特的鞭毛虫样红斑。我们报告一例61岁的白种男性，他在食用生香菇1天后，躯干和四肢出现伴有瘙痒的、呈多条线状条纹的红斑疹。在用外用类固醇和口服抗组胺药治疗后，他的症状和皮肤损害在大约1周内消退，仅留下轻微色素沉着。皮肤活检显示非特异性 findings，包括稀疏的血管周围和间质性皮炎以及局灶性空泡界面改变。我们的病例表明，这种情况是一种临床表现明显的皮炎，病程自限。皮疹的发病机制尚不清楚。
