Nicolau Syndrome Following Intralesional Sclerotherapy: A Dreaded Complication of a Simple Office Procedure

Introduction: Nicolausyndromeisaniatrogenic dreaded adverse skin reaction leading to ischemic necrosis of skinandunderlying tissue after parenteral drug injection. The etiopathogenesis is poorly understood. However, inflammation, reflex vasospasm, and thrombo-embolic occlusion of blood vessels, including arterioles and arteries, are suggested as the cause of ischemia. Case Presentation: We report a 12-year-old girl who developed Nicolau syndrome after a simple office procedure of intralesional sclera therapy with sodium tetradecyl sulfate for a apyogenic granuloma on her right index finger. Three days later, she reported complaints of excruciatingly painful swelling with bluish discoloration of the right hand involving the palm, entire index, middle, and ring fingers, and distal part of the little finger. Nicolau syndrome was documented after intramuscular injections of drugs. Nevertheless, there are very few reports of Nicolau syndrome following post intralesional sclerotherapy. Conclusions: Sclerotherapy is a simple office procedure routinely performed by health care professionals (e.g., dermatologists and surgeons), and awareness about its dreaded entity is key. Stringent precautions and prompt management can prevent unfavorable complications. Additionally, prudent patient selection and detailed counseling with explicit informed consent regarding Nicolau syndrome are imperative while planning any parenteral drug injection or intralesional sclerotherapy to avoid litigation.
