Habitual khat () chewing has been proven to cause numerous oral tissue changes. However, oral melanoacanthoma triggered by chronic khat chewing is rare. Oral melanoacanthoma is an uncommon, sudden, asymptomatic, benign pigmentation of the oral cavity. Under the microscope, the epithelial layer of the oral mucosa showed dendritic melanocyte proliferation and acanthosis. The study aimed to highlight chronic khat chewing as a trigger for oral melanoacanthoma.
In the current study, we report a case of a 26-year-old male patient with a rare presentation of oral melanoacanthoma triggered by regular khat chewing. Many intrinsic and extrinsic factors can cause oral pigmentation. Chewing khat is an extrinsic factor that can cause several diseases, including oral pigmentation. In this case, the definitive diagnosis was oral melanoacanthoma. This diagnosis was made based on the patient's history, clinical lesion presentation, and microscopic biopsy results.

已证实习惯性咀嚼巧茶会导致众多口腔组织变化。然而，由慢性咀嚼巧茶引发的口腔黑素棘皮瘤较为罕见。口腔黑素棘皮瘤是一种口腔内罕见、突发、无症状的良性色素沉着。在显微镜下，口腔黏膜上皮层显示树突状黑素细胞增殖和棘层肥厚。本研究旨在强调慢性咀嚼巧茶是口腔黑素棘皮瘤的一个触发因素。
在本研究中，我们报告了一例26岁男性患者，其因经常咀嚼巧茶引发了罕见的口腔黑素棘皮瘤。许多内在和外在因素均可导致口腔色素沉着。咀嚼巧茶是一种可引发多种疾病（包括口腔色素沉着）的外在因素。在此病例中，最终诊断为口腔黑素棘皮瘤。该诊断基于患者的病史、临床病变表现及显微镜下活检结果。
