Angular cheilitis - 角度性唇炎
主要原因是慢性濕疹和唇部相關感染。營養不良通常不是原因。

此疾病可以單獨出現，也可以作為某些更廣泛的健康問題（如維生素 B12 或鐵水平低引起的貧血）或局部感染（如皰疹和口腔念珠菌病）的一部分出現。唇炎也可能是由於對刺激性或過敏性物質的反應而發生，或者可能由陽光 (actinic cheilitis) 或某些藥物（尤其是類維生素A）引發。已報告了幾種形式的唇炎 (angular, contact (allergic and irritant) , actinic, glandular, granulomatous, exfoliative and 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.

口角炎是一個相當常見的問題，據估計它影響著 0.7% 的人口。它最常發生在30歲至60歲的人群中，在兒童中也相對常見。
口角炎可由感染、刺激引起。感染包括真菌和細菌。在發展中國家，鐵和維生素缺乏可能是原因。
○ 治療 - 非處方藥
將非處方抗生素軟膏塗抹在病變部位，每天兩次，持續數天。嘴唇上反覆出現的濕疹可能是嘴唇乾裂的主要原因。這種情況，同時治療濕疹可以預防復發。在已開發國家，營養不良很少是原因。
