Abstract

Human T-lymphotropic virus 1 (HTLV-1) is the etiological agent of several pathologies, and some of them are not investigated, resulting in a lack of literature that impacts the correct diagnosis. Skin manifestations, such as HTLV-1-associated infectious dermatitis (IDH), are common in patients living with HTLV-1 but could not be the only one. Here, we report for the first time a patient infected with HTLV-1, without previous diagnosis of HTLV-1-related diseases, presenting erythema nodosum (EN). Given the patient's long-term asymptomatic carrier status, the emergence of EN underscores the importance of considering HTLV-1 in the differential diagnosis when encountering EN, especially in endemic regions.

结节性红斑是 HTLV-1 感染的一种非典型皮肤病表现：病例报告和文献综述。

人类 T 淋巴细胞增多病毒 1（HTLV-1）是多种病症的病原体，其中一些病症尚未得到研究，因此缺乏影响正确诊断的文献资料。皮肤表现，如 HTLV-1 相关感染性皮炎（IDH），在 HTLV-1 患者中很常见，但不可能是唯一的皮肤表现。在此，我们首次报告了一名感染 HTLV-1 的患者，该患者既往未确诊过与 HTLV-1 相关的疾病，却出现了结节性红斑（EN）。鉴于患者长期处于无症状携带状态，结节性红斑的出现强调了在遇到结节性红斑时将 HTLV-1 列入鉴别诊断的重要性，尤其是在地方病流行地区。
