Case report describes a 55-year-old woman with buccal lymphoepithelial cyst and fistula, highlighting rare findings.
Oral lymphoepithelial cyst (LEC) with sebaceous gland differentiation and buccal fistula is extremely rare. A 55‐year‐old woman presented with a 25 mm × 25 mm mass in the right buccal mucosa and a fistula near the angle of the mouth. CT showed continuity between the mass and the fistula. Cystectomy and fistulectomy were performed. Histopathology confirmed LEC with lymphoid follicles and sebaceous glands. We report a rare case of oral LEC with sebaceous gland differentiation and buccal fistula. No recurrence was observed 2 years postoperatively.
