Alopecia areata is an inflammatory, non-scarring hair loss associated with autoimmune conditions. It is more commonly seen with thyroid disorders and vitiligo, but alopecia areata has also been linked to diabetes, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. Indeed, individuals with alopecia areata have an increased risk of developing systemic lupus erythematosus. A 36-year-old woman presented with hair loss characteristic of alopecia areata. After intralesional injections with triamcinolone acetonide, the areas of hair loss exhibited near complete hair regrowth. Laboratory examination and additional history were suggestive of systemic lupus erythematosus. She was referred to a rheumatologist who confirmed the diagnosis. Awareness of the comorbidities associated with alopecia areata can uncover other autoimmune conditions, such as thyroid disorders and systemic lupus erythematosus. The diagnosis of a new-onset alopecia areata may prompt a deeper investigation of potentially associated conditions.
斑秃是一种与自身免疫性疾病相关的炎症性、非瘢痕性脱发。它更常见于甲状腺疾病和白癜风，但斑秃也与糖尿病、银屑病、类风湿性关节炎和系统性红斑狼疮有关。事实上，斑秃患者患系统性红斑狼疮的风险增加。一名36岁女性出现斑秃特征性的脱发。在皮损内注射曲安奈德后，脱发区域几乎完全重新长出头发。实验室检查和进一步询问病史提示患有系统性红斑狼疮。她被转诊给一位风湿病学家，后者确诊了该疾病。认识到与斑秃相关的合并症可以发现其他自身免疫性疾病，如甲状腺疾病和系统性红斑狼疮。新发斑秃的诊断可能会促使对潜在相关疾病进行更深入的调查。
