Erythema induratum of Bazin is a rare entity, the cause and treatment of which are topics of continuing controversy. This report documents the cases of two patients with ulcerating leg nodules. One patient had concurrent active pulmonary tuberculosis, and the other had a history of previous treatment for pulmonary tuberculosis. The treatment regimen for these patients is outlined. First described by Bazin, the rare entity of erythema induratum was thought to be of tuberculous origin or a tuberculid reaction. Opinion has varied, and some authors have classified this condition as a vasculitis involving subcutaneous vessels. Because of the rarity of this disorder and the controversy surrounding its cause and pathogenesis, we share our experience with two patients whose clinical and pathologic findings were consistent with the diagnostic criteria for erythema induratum and in whom there was a recent or remote history of tuberculosis.
巴赞硬红斑是一种罕见疾病，其病因及治疗方法一直存在争议。本报告记录了两名患有腿部溃疡性结节患者的病例。一名患者同时患有活动性肺结核，另一名患者有既往肺结核治疗史。文中概述了这些患者的治疗方案。硬红斑这种罕见疾病最早由巴赞描述，曾被认为源于结核或结核疹反应。观点各异，一些作者将此病症归类为累及皮下血管的血管炎。鉴于该疾病的罕见性以及围绕其病因和发病机制的争议，我们分享两名患者的经验，他们的临床和病理表现符合硬红斑的诊断标准，且有近期或既往肺结核病史。
