Conclusion
Epidermoid cyst of the buccal mucosa is extremely rare. Nevertheless, it
must be included in the differential diagnosis of swelling in this area.
To exclude other conditions, like benign tumors and odontogenic
infection, appropriate imaging techniques are necessary in preoperative.
The diagnosis is based on anatomopathological exam. The surgical
enucleation is the gold standard of treatment, and usually without
recurrence.
