Acquired ichthyosis usually reveals or is associated with an internal disease. The classical clinical aspect is vulgaris ichthyosis. We report a case of acquired ichthyosis, presenting original clinical features, revealing a lymph node tuberculosis.
A 63-year-old male patient without past history of skin disease consulted for a generalized eruption. The eruption was composed of multiple erythemato-squamous plaques. The edge of the plaque was raised and circinated. Histologic examination of the edge and the centre of the lesion supported the clinical diagnosis of ichthyosis. The diagnosis of lymph node tuberculosis based on large inguinal nodes was confirmed by the fast acid-bacilli found in the lymph node. Initiation of antituberculosis therapy was followed by the rapid and complete disappearance of the skin lesions.
We report a case of acquired ichthyosis with original clinical features and we propose to coin the term "acquired circinated ichthyosis". This entity was clinically distinct from ichthyosis vulgaris or pityriasis rotunda. This dermatosis was concomitant to lymph node tuberculosis and healed under antituberculosis therapy.
获得性鱼鳞病通常揭示或与一种内科疾病相关。典型的临床外观是寻常型鱼鳞病。我们报告一例获得性鱼鳞病病例，呈现出独特的临床特征，揭示了淋巴结结核。
一名63岁男性患者，既往无皮肤病史，因全身性皮疹前来就诊。皮疹由多个红斑鳞屑性斑块组成。斑块边缘隆起且呈环状。对病变边缘和中心进行组织学检查支持鱼鳞病的临床诊断。基于腹股沟大淋巴结诊断为淋巴结结核，淋巴结中发现的抗酸杆菌证实了这一诊断。开始抗结核治疗后，皮肤病变迅速完全消失。
我们报告一例具有独特临床特征的获得性鱼鳞病病例，并提议创造“获得性环状鱼鳞病”这一术语。该实体在临床上与寻常型鱼鳞病或钱币状糠疹不同。这种皮肤病与淋巴结结核同时存在，并在抗结核治疗下治愈。
