RESUMEN
Lymphoepithelial cyst of the oral cavity is a rare cystic lesion that presents as an asymptomatic, well-circumscribed, yellowish small submucosal nodule covered by normal overlying mucosa, usually located in the floor of the mouth or in the ventral or posterolateral surface of the tongue. Histopathological examination reveals a cyst lined by a stratified squamous epithelium surrounded by lymphoid tissue. In this paper, we report two cases of oral lymphoepithelial cyst, one on the anterior floor of the mouth and another on the posterior lateral tongue. In both cases, the patients were women aged approximately 50 years and the lesions were treated by local surgical excision, with no evidence of recurrence after 2 years of follow-up.

A case of spontaneous bone regeneration after mandibulectomy is presented. The patient was young and had a mandibular resection performed for a large fibroma. Only one of the condyles was preserved. Partial preservation of the periosteum may play an important role in rapid bone regeneration. In this case bone regeneration occurred only in mandibular regions where the periosteum could be preserved.
