Abstract
BACKGROUND
Habitual khat (Catha edulis) 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.
CASE SUMMARY
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.
CONCLUSION
Habitual khat (Catha edulis) chewing causes many oral tissue changes including oral melanoacanthoma. The study aimed to highlight chronic khat chewing as a trigger for oral melanoacanthoma.
