Epidermoid cyst of floor of mouth

Epidermoid cysts are developmental malformations which are soft, mobile and slow-growing masses and they are unattached to the overlying skin. The most common cervical location of these cysts is the floor of the mouth without any gender predilection. The following report presents a case on epidermoid cyst and its management and a discussion on various differential diagnoses. This report presents a case with a painless swelling over the floor of mouth with dysphagia, dysarthria and orthopnea. Thorough history and examination of the swelling was done. Preoperative assessment was made with CT imaging. Complete surgical excision of the mass was done via intraoral approach under general anaesthesia with an uneventful recovery period. Swellings over the floor of mouth can be congenital, infectious, inflammatory or tumours. Preoperative evaluation can be done by taking thorough history, examination and radiological imaging. Surgical excision is the treatment of choice for epidermoid cysts with approach based on its relation with the mylohyoid muscle.
