Teratoid cyst of the floor of the mouth

Nonodontogenic cysts of the oral and maxillofacial region: demographic profile in a Brazilian population over a 40-year period

“…), and the presence of respiratory and/or gastrointestinal tissues inside the capsule [45]. Teratoid cysts of the oral cavity are rare, accounting for approximately 1.8% of all dermoid cysts [46]. Retrospective studies revealed no gender preference of teratoid cysts [45,47].…”

“…Retrospective studies revealed no gender preference of teratoid cysts [45,47]. The lesions are typically found in the floor of the mouth [45,46,48]. At this anatomic site, teratoid cysts are usually diagnosed during childhood [45].…”

Choristoma Involving the Floor of the Mouth and the Anterior Tongue: A Case of Teratoid Cyst With Gastric and Respiratory Epithelia

“…In the literature, congenital cysts on the floor of the mouth are usually generally named as "dermoid" but from an histological point of view, they had been properly classified as epidermoid (lined by just squamous epithelium), true dermoid (when skin adnexa are found within the cyst wall) or teratoid (when also mesodermal elements such as bone, muscle, respiratory and gastrointestinal tissues, and a fibrous capsule are found) [2,3]. Cysts located on the floor of the mouth account for 1.6% of all the "dermoid" cysts from the head and neck region [4], and among them teratoid cysts are the least common accounting for about 1.8% [5]. Nevertheless the floor of the mouth and the tongue represent the almost exclusive location of oral teratoid cysts as described in a report of 31 cases, where the floor of the mouth was the most frequent location (71% of cases) followed by the tongue (29% of cases) [6].…”

“…Still the controversy about the nomenclature used for these cysts is evident from the various terms found in the literature (choristomatic cyst, foregut cyst, ciliated epithelial cyst, anterior median lingual cyst, lingual duplication cyst, cystic tumor of the tongue, unusual thyroglossal duct cyst, enterocystoma, alimentary tract cyst, heterotopic gastrointestinal cyst of the oral cavity), so that it has been suggested to nominate them considering the main type of epithelial lining [7,8]. 5 Oral cysts with gastrointestinal epithelium were first described in 1895 [9] and in 1999 almost 40 additional cases had been reported [10]. Conversely cysts showing both gastrointestinal and respiratory other than squamous epithelium seem to be more uncommon with only 3 cases described till 1996[11] and no more than 11 additional cases reported in the following years [6,[12][13][14].…”

Intracranial Dysontogenetic Tumors In Children: Topographic-Histologic Correlations, Own Experience And Review Of The Literature

“…Depending on location and organs involved, they pose a challenge for neurosurgeons, dermatologists and cosmetologists, general surgeons, gynecologists, pediatricians, ophthalmologists, ENT specialists and, ultimately, pathologists, if only due to ambiguous diagnostic criteria and inconsistent nomenclature. DTs of virtually any location have been described, including orbit [1], intracranial [2], intralingual [3], parotid [4,5], floor of the mouth [6], testes [7], ovaries [8], omentum [9] and nose [10] to name just a few.…”
