MARTINS, S; NETO, T; SOARES, J  e  BALHAU, R. Large dermoid cyst of the floor of the mouth. An emphasis on differential diagnosis. Rev Esp Cirug Oral y Maxilofac [online]. 2019, vol.41, n.3, pp.149-152.  Epub 30-Mar-2020. ISSN 2173-9161.  https://dx.doi.org/10.20986/recom.2019.1040/2019.

This article presents the case report of a giant lateral dermoid cyst in the floor of mouth surgically excised by intraoral approach, initially misdiagnosed by imaging studies as a ranula. Other cases of dermoid cysts preoperatively diagnosed ranulae are present in literature, but none directly compares their clinical, radiological and therapeutic aspects. This article will also discuss these aspects in order to possibly aid in their correct diagnosis and management.

Palavras-chave : Dermoid cyst; ranula; floor of the mouth; intraoral approach.
