We present the case of a dermoid cyst with an oral and a submental component in a 21-year-old Japanese woman who presented with complaints of a mass in the oral cavity and difficulty in chewing and swallowing solid foods for about 2 years. MRI shows a 55 × 65 mm well-circumscribed cystic mass extending from the sublingual area to the mylohyoid muscle. Under general anesthesia and with nasotracheal intubation, the patient underwent surgical removal of the mass. Although the cyst was large and extending mylohyoid muscle, intraoral midline incision was performed through the mucosa overlying the swelling and the cyst was separated from the surrounding tissues with appropriate traction and countertraction and successfully removed without extraoral incision. Oral approach in surgical enucleation is useful procedure to avoid cosmetic problems in large and extending mylohyoid muscle cyst.

    • "Several theories have been proposed to explain the development of dermoid cysts. The preponderant one suggests that they develop from the entrapment and consequent growth of epithelial cells from the first (mandibular) and the second (hyoid) branchial arches (Ohta et al. 2012). Another theory suggests that traumatic implantation from surgical or accidental injury Τόμος 15, Νο 3, 2014/Vol 15, No 3, 2014 Εικ. 1.

    ABSTRACT: Introduction: Dermoid cysts are rare congenital lesions derived from pluripotential cells. They represent less than 0.01% of all oral cavity cysts and are also called non-odontogenic cysts. Dermoid cysts are frequently found in sites where embryonic parts fuse together. The majority of reported cases are in the midline of the body, as well as in the ovaries and in the testicles Patients and Methods: A retrospective analysis study that spanned the period of 2000-2012 was carried out at the Oral and Maxillofacial Surgery clinic of the Ahmadu Bello University Teaching Hospital, Zaria. The parameters studied included age, sex, duration of swelling, site, co-morbidity, complications and treatment. Results: Of the 16 patients, 10 (62.5%) were males and 6(37.5%) females in a ratio of 1.67:1, the age ranged between 2 months and 49 years. Of all the cysts, 11 were sublingual, 3 in the cheek, 1 sublingual-submental and1 lingual; 6 (37.5%) patients had co-morbid symptoms and the most common was Upper respiratory tract infection (100%) followed by anemia (2 patients) and measles one patient. Conclusion: Dermoid cysts can be congenital or acquired. Their early presentation were associated with both feeding and respiratory symptoms.

    ABSTRACT: The teratoid cyst is a rare variant of the dermoid cyst which seldom occurs in the oral cavity. If seen, they generally present as slow growing cysts of the floor of mouth, reported commonly in the 2(nd) and 3(rd) decade of life in males. Histopathologically, dermoid cyst is classified as epidermoid cyst, true dermoid cyst and teratoid cyst depending on the presence of adnexal structures and derivatives of all three germ layers. Herewith we report a rare case of teratoid cyst of the floor of the mouth, in a 2-year-old female child, which was present since birth.
