Cutaneous tuberculosis is a rare manifestation of extrapulmonary tuberculosis caused by Mycobacterium tuberculosis in most cases and rarely by Mycobacterium bovis. Diagnosis may be challenging due to a wide range of clinical findings and similarities to other chronic dermatoses, leading to delayed treatment. We present a case of scrofuloderma in a 4‐year‐old girl that arose from a contiguous spread from the anterior mediastinum with associated pulmonary involvement.

胸部瘰疬病伴纵隔结核

皮肤结核是肺外结核的一种罕见表现，是由皮肤结核引起的。结核分枝杆菌在大多数情况下，很少由牛分枝杆菌。由于广泛的临床表现以及与其他慢性皮肤病的相似性，诊断可能具有挑战性，从而导致治疗延迟。我们介绍了一名 4 岁女孩的瘰疬皮病病例，该病是由前纵隔的连续扩散引起的，并伴有肺部受累。
