A review of scientific literature reveals a sparse documentation of periungual pyogenic granulomas as an adverse effect of isotretinoin therapy
Periungual pyogenic granulomas appeared in four patients receiving isotretinoin therapy for severe acne. Oral and topical antibiotic treatments were ineffective and all cases spontaneously resolved once isotretinoin is discontinued.
This report demonstrates the idiosyncratic nature of this side effect. We suggest that, although infection is possible due to the transformed nature of the normally protective skin barrier, oral and topical antibiotic treatments appear ineffective. Pyogenic granulomas spontaneously resolve once isotretinoin is discontinued.
对科学文献的回顾显示,关于异维A酸治疗的不良反应中,甲周化脓性肉芽肿的记录稀少。
4例接受异维A酸治疗重度痤疮的患者出现了甲周化脓性肉芽肿。口服和外用抗生素治疗无效,一旦停用异维A酸,所有病例均自行消退。
本报告证明了这种副作用的特异性。我们认为,尽管由于正常保护性皮肤屏障的改变可能导致感染,但口服和外用抗生素治疗似乎无效。停用异维A酸后,化脓性肉芽肿会自行消退。
