Lingual dermoid

Abstract

Dermoid cysts are congenital lesions derived from ectodermal differentiation of multipotential cells. Only 7% of all dermoid cysts occur in the head and neck region and about a quarter of them are seen in the floor of mouth. Dermoids confined to the tongue are rare entities. Only 13 such cases, mostly in infants, have been reported in literature. One such case of an infant with intralingual dermoid and feeding difficulty, relieved following cyst excision, is reported.

Dermoid cyst of the tongue: An association of dermoid cyst with bronchogenic epithelium

“…Dermoid cysts of the body of the tongue are rarer than those of the floor of the mouth. Twenty cases have been reported in the literature (Rise, 1964;Lipsett et al, 1993;Chaari et al, 1995;Valtonen et al, 1986;Flom et al, 1989;Reddy et al, 1991;Bisschop et al, 1985;Mathur and Menon, 1980;Goldberg, 1965;Towne and Hurst, 1997).…”

“…Gold et al, 1974;Chaari et al, 1995;Reddy et al, 1991;Bisschop et al, 1985;Wiersma et al, 1992). The presence of a sinus tract favours the diagnosis of a dermoid cyst.…”

Dermoid Cyst of the Floor of the Mouth Diagnosed by Fine Needle Aspiration Cytology

“…24,33 Due to the nature of its contents, these cysts do not transilluminate. 49 Geniohyoid cysts, which lie between the geniohyoid and mylohyoid muscles, can produce a swelling in the midline near the chin, 32 simulating the appearance of a double chin. 6,8,14,30,34,39,42,54,58 Sometimes a large cyst can herniate through the mylohyoid muscle, producing a dumbbell-shaped mass that can be palpated both intraorally and extraorally.…”
