References该疾病既可单独出现，也可作为更广泛健康问题（如维生素 B12 或铁缺乏导致的贫血）或局部感染（如疱疹和口腔念珠菌病）的一部分出现。唇炎还可能因对刺激性或过敏性物质的反应而发生，亦可能由阳光 (actinic cheilitis) 或某些药物（尤其是类维生素A）诱发。已报道的唇炎形式包括：angular、contact (allergic and irritant)、actinic、glandular、granulomatous、exfoliative 和 plasma cell cheilitis。
The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis.

口角炎是一种相当常见的疾病，估计约有 0.7% 的人群受其影响。最常见于30至60岁的成人，儿童中也相对常见。
口角炎可由感染或刺激引起，感染包括真菌和细菌。在发展中国家，缺铁和维生素缺乏可能是诱因。
○ 治疗—非处方药
将非处方抗生素软膏涂于病变部位，每日两次，连续使用数天。嘴唇反复出现的湿疹可能是导致干裂的主要原因，此时治疗湿疹可预防复发。在发达国家，营养不良很少是致因。
