“…13 It is also notable that not all published teratomas were located strictly inside the Eustachian tube but bulged into the nasopharynx through a long pedicle. 8,10,14 Our case showed no extension of the tumor toward the airways, explaining the absence of respiratory symptoms in our child.…”

“…Until 2013, only 16 cases had been reported in the literature, originating here. 2,[8][9][10] It is a tumorlike malformation containing cells from all the 3 germ layers (endoderm, mesoderm, ectoderm). Different names had been assigned to these teratomas, according to the various proportions and nature of its cells: mature teratoma, malignant teratoma, epignathus.…”

Introduction: Teratomas, tumors derived from all 3 fetal germ cell layers, are rarely located in the head and neck region and extremely rare in the Eustachian tube area. Case report: The authors present the case of a 2 years old child with chronic ear discharge. Referral diagnosis was tumor or cyst of the temporal bone. Intraoperatively, a solid, hairy tumor located inside the Eustachain tube, with extension into the middle ear space was discovered and removed. Histology revealed a mature teratoma. Review of the literature showed reports of rare similar cases of Eustachian tube teratomas, differentiating themfrom hairy polyps of the rhynopharynx. The imaging of our patient, the surgical techique for removal of the tumor and long term follow-up are detailed. Conclusions: Teratomas located inside the Eustachian tube are exceptional. Their removal should be carefully planned in view of their long term anatomical sequelae and in order to avoid long term postoperative morbidity.

“…Middle ear includes tympanum, tympanic antrum, mastoid and ET, therefore the teratoma derived from the ET and extended down to the nasopharynx in one patient was included [ 9 ]. In this study, 19 females: 3 males, approximating the generally accepted sex ratio of 6 females:1 male for teratomas.…”

Background: Teratoma is a true neoplasm composed of a number of different types of tissue derived from the three germinal layers but rarely occurs in the middle ear (ME). The features of middle ear teratomas (MET) have not been well described. Objective: The objective of this study is to explore the clinical and imaging features of MET, and report 2 rare cases of MET with ear malformation that have never been reported. Materials and methods: The clinical, CT and MRI data of 8 patients with a pathological diagnosis of MET were collected and retrospectively mined, and 14 patients with MET reported in previous literature were also reviewed. Result: ① Female, left ear predominance in MET, and the most common symptoms were otorrhea and hearing loss. ② On CT and MRI, the MET presented as an irregular soft tissue mass that was heterogeneous, with fatty tissue and involved multiple sites, and the ET and tympanum were correspondingly expanded and locally destroyed. ③ Mictotia with MET in two patients was presented, which was the first report. Conclusion: MET has female sex and left ear predominance. CT and MRI can be used to diagnose MET and display its extent and its relationship to the carotid canal in detail. Complete surgical excision is the definitive treatment.
