Dermoid cyst is a benign neoplasm, so called by teratoma that is derived from both ectoderm and mesoderm during embryonic period. The majority of dermoid cysts are found in the ovaries and approximately only 7% of dermoid cysts are found in the head and neck. The growth of dermoid cysts in the floor of the mouth is considered a rare condition. We report one case of huge dermoid cyst in the floor of mouth suffered with double chin appearance and difficulty in pronunciation and respiration. The cyst was excised successfully only intra-oral incision. Clinical progress was uneventful and postoperative recovery excellent without recurrence.

Background: Dermoid cysts of the auricular area are extremely rare. We report on six cases of auricular dermoid and epidermoid cyst, and differentiate dermoid cyst from epidermal cyst along with a review of the literature. Methods: Three cases involved a gradually enlarging mass of the superior and anterior aspect of the helix of their ear. Another two cases were located in the posterior aspect of the ear. Results: During the operation, a tumor was found just under the skin, not fixed mastoid or adjacent cartilage. Histologically, all specimens contained desquamated squamous epithelium and keratin in the lumen. However, two cases of posterior masses showed the presence of adnexal structures and three cases did not. Conclusion: A key in diagnosis of the dermoid cyst is the presence of adnexal structures. If the wall does not bear adnexal structures, the term epidermoid or keratin cyst is applied. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Finally, the congenital epidermoid cyst grew at the upper part of the auricle; however, the dermoid cyst grew at the lower and posterior part of the auricle.

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into the right temporal base and the posterior fossa with findings of ruptured cyst. Surgical resection was performed, and pathological findings were confirmed to be a dermoid cyst. We report a second case with ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa.

Although lipomyelomeningocele and dermoid cyst are formed during a similar embryologic developmental stage of 'neural tube formation', they are caused by entirely different embryologic mechanisms. We encountered a case, which has not been previously reported, that had a lumbar subcutaneous dermoid cyst associated with lipomyelomeningocele. A 52-year-old man presented with a slowly growing lumbar mass of 3 years duration, which had been present since birth. Lumbosacral magnetic resonance imaging[MRI] showed lipomyelomeningocele at the L3, 4 and 5 levels and a subcutaneous cystic mass of high signal intensity on the T2 weighted image and iso or low signal intensity on the T1 weighted image. He underwent total resection of the lumbar subcutaneous mass. Intraoperative findings and histological examination were consistent with the preoperative diagnosis of a 'dermoid cyst'. We demonstrate that the formation of a dermoid cyst might coexist with lipomyelomeningocele during the embryologic developmental stage.

A dermoid cyst is a rare congenital midline neck mass with usually develops in the submental region. It is most often seen in young adults and can become rather large than almost no symptoms. As it increases in size, dysphasia, or dyspnea can develop. The differential diagnosis of the midline lesion includes ranula, thymglossal duct cyst, cystic hygroma, and cystic lymphangioma. The treatment of choice is complete surgical removal. With a review of the literature, we report two cases of a huge dermoid cyst inducing dyspnea.

Dermoid cysts located in the floor of the mouth are very rare developmental keratinizing squamous epithelium lined cysts. Anatomically, they are classified as sublingual (median genioglossal), submental (median geniohyoid) and lateral dermoid cysts, and they can be further classified as epidermoid, dermoid, and teratoid cysts by histology. We report a case of sublingual dermoid cyst in a 16-year-old boy presenting as a large sublingual swelling causing speech and swallowing difficulties and discuss the surgical treatment techniques and histopathological features of this lesion.

The author has diagnosed and treated the dermold cyst patient in the 41 years old korean man. The dermold cyst in the floor of the mouth had various sign and symptom such as elevated tongue, disturbance of speech and swallowing, and etc. The cyst wall of dermoid cyst was enucleated by using of direct enucleation of cyst wall and primary suture technique. The mass of the enucleated dermoid cyst was 5×5.5×6 Cm.in size.

Dermoid cyst of the floor of mouth is infrequent. This cyst has been classified as epidermoid, dermoid and teratoid cyst. Dermoid cyst is more common in young adults and no sex predilection and has generally been present for months to years before progressive enlargement causes interference with the mobility of the tongue and disturbance of articulation and mastication. The authors have recently experienced dermoid cyst of the floor of mouth which was confirmed histopathologically.

유피낭종(dermoid cyst)은 표피형태의 상피세포로 이루어진 낭종의 벽에 피부부속조직을 포함하는 발생학적 낭종이다. 눈썹 부근이나 구강저의 중심선에 호발하지만 혀, 입술, 협점막의 병소도 보고된 바 있다. 이 병소는 천천히 커지고 무통성이며 임파선비대는 동반하지 않는다. 내용물은 피지성, 화농성등이며 크기는 수 mm에서 12cm까지 다양하다. 조직학적 특징은 상피세포 이장과 낭종벽내의 땀샘, 피지샘, 모낭동의 피부부속조직의 존재이다. 유피낭종의 치료는 완전절제이다 완전한 절제시 재발의 가능성은 거의 없다. 본 증례의 2세 여자환아는 1년 전에 넘어진 이후 상순에 딱딱한 것이 생겼다는 것을 주소로 연세대학교 치과대학병윈 소아치과에 내원하였다. 임상 구강검사 결과 둥근 고무질감의 종괴가 상순에서 관찰되었다. 조직학적 검사를 위해 조직생검을 시행하였으며, 낭종의 벽에서 피지샘이 관찰되었다. 이에 상순에서는 드물게 발생하는 유피낭종으로 진단되어 보고하는 바이다.

Midline craniofacial dermoids are rare lesions resulting from the abnormal fusion of embryologic structures. The clinical features of craniofacial dermoid cysts show a range of presentations, including infection, asymptomatic puncti, or seizure secondary to intracranial invasion. Appropriate management involves an accurate diagnosis of the dermoid cyst and a complete resection.
