Introduction: Dermoid/Epidermoid cysts are rare pathologic lesions that may involve the floor of the mouth. Infection and inflammation of the cyst can produce a clinical picture very similar to the submandibular and submental abscesses with odontogenic origin. Dermoid/epidermoid cysts are on the floor of the mouth with submental or submandibular component can be mistaken for odontogenic infections. Methods: Four biopsy proven dermoid/epidermoid cysts operated in the Mashhad University of Medical Sciences, Ghaem hospital (2012-2013), were reviewed. Results: Four patients, including two classic cases and two infected dermoid/epidermoid cysts, were erroneously diagnosed as odontogenic infection. Discussion: The lesions located solely below mylohyoid muscle need to be removed through anextraoral approach but the lesions above the mylohyoid muscle or those that have both supra- and infra-mylohyoid components can be removed through an intraoral incision.Conclusion: Dermoid/epidermoid cysts should be considered in the differential diagnosis of submental/submandibular swellings. In the absence of an odontogenic cause of infection, fine-needle aspiration biopsy and appropriate imaging evaluation techniques with sonography, CT or MRI are mandatory for correct diagnosis and surgical treatment planning. The clinicians should be very cautious to differentiate odontogenic infections from infected dermoid/epidermoid cysts.
