Epidermoid cysts are rare, slow-growing, benign, developmental cysts that arose from abnormally situated ectodermal tissue. They represent less than 0.01% of all oral cavity cysts and in particular those of the submandibular region are extremely rare. A detailed analysis of the patient’s clinical features and a study of the extent, nature and exact location of the lesion provided by MRI are essential for appropriate preoperative surgical planning. The recommended treatment for epidermoid cysts of the mouth floor is surgical enucleation. The position of the mylohyoid muscle and the size of the cysts generally dictate the surgical approach. The authors present and discuss the management of the first case in literature of an epidermoid cyst extending in submandibular region through the mylohyoid muscle removed by an intraoral surgical approach without any resultant morbidities and with no evidence of recurrence up to the one-year follow-up. With this approach, we managed to avoid visible cutaneous scars provided the patient with excellent cosmetic and functional outcomes.
