Popis: Dermoid cysts are uncommon soft tissue lesions considered developmental in origin that may occur in many body sites but predominate in the ovary and scrotal regions. Their etiology is unclear; however, one theory suggests that they may be caused by entrapment of germinal epithelium with potential to differentiate along ectodermal, mesodermal and endodermal lines. Seven percent of dermoid cysts can be found in the head and neck regions. This represents less than 0.01% of all intraoral cysts. Most intraoral dermoid cysts are found as midline masses in the floor of the mouth followed by the submandibular and sublingual region. Dermoid cysts of the jawbones are exceedingly uncommon. To date, only 20 cases have been documented in the English language literature. A small number of extragnathic bony lesions have also been reported. The histologic classification of gnathic dermoid cysts in the current literature is confusing with lesions being described as orthokeratinizing cysts exhibiting sebaceous differentiation, odontogenic keratocysts with sebaceous differentiation, variants of dentigerous cysts and dermoid cysts. Here, we attempt to clarify the literature as well as report an additional case of a gnathic dermoid cyst in a 40-year-old female who presented with a well-defined radiolucency of her left mandible extending from her premolars to the molar region
