Erythema nodosum is not an uncommon dermatologic entity. Sarcoidosis and streptococcal infection have become the two most common causes, while tuberculosis was the predominant etiology prior to the use of isoniazid. Histoplasmosis and coccidioidomycosis are two important geographic considerations. Laboratory tests should include a PPD test, chest x-ray, throat culture for beta-streptococcus, and ASO titer determination as a minimum. Symptomatic treatment remains unsatisfactory in many cases, although recent success has been reported with oral potassium iodide.
结节性红斑是一种并不罕见的皮肤病症。结节病和链球菌感染已成为最常见的两大病因，而在使用异烟肼之前，结核病是主要病因。组织胞浆菌病和球孢子菌病是两个重要的地域相关考量因素。实验室检查至少应包括结核菌素试验、胸部X光检查、β-链球菌咽拭子培养以及抗链球菌溶血素O滴度测定。尽管最近有报道称口服碘化钾取得了成功，但在许多情况下，对症治疗仍不尽人意。
