Dermoid cysts are rare benign cystic lesions encountered in the head and neck region. Only 7% of dermoid cysts occur in the head and neck area of which only 1.6% appears in the oral cavity. Still rarer is the presentation of the dermoid cyst in the maxillofacial region in a pediatric patient, which is about 0.29%. Herein, we report a pediatric case of a female patient of 13 years old who came with the chief complaint of swelling below the chin since 8 years. Th e purpose of this case report is to emphasis on the rarity of the condition and how important it is to be considered in the differential diagnosis of lesions seen in relation to floor of mouth.
