Germ cell tumors of the ovary arising after dermoid cyst resection: a long-term follow-up study.

OBJECTIVE: To study the long-term ovarian neoplastic consequences of resection of a dermoid cyst. METHODS: The study population comprised 99 patients who were operated on for an ovarian dermoid cyst. Follow-up information was obtained for 91 women for a mean period of 5.06 +/- 2.46 years. RESULTS: Of the 99 women, 18 had bilateral dermoid cysts. Multiple dermoid cysts in a single ovary were found in nine of the women with bilateral cysts and in one of the remaining patients. Two patients developed malignant germ cell tumors, and three developed a recurrent dermoid cyst in an ovary from which a dermoid cyst had previously been extracted. Bilateral or multiple ovarian dermoid cysts were present at the initial operation in four (80%) of these patients. CONCLUSIONS: Women with bilateral or multiple dermoid cysts may include a subgroup of patients with a greater tendency to develop future ovarian germ cell neoplasms.

[Cavernous sinus dermoid cyst with unusual parapharyngeal development].

We report a case of dermoid cyst arising in the cavernous sinus and parapharyngium areas through the foramen lacerum. A 12-year-old girl was hospitalized in October 1966 for progressive intracranial hypertension. CT before a prior surgical intervention in 1994 showed an intracranial process suggesting a dermoid cyst. CT performed in October 1996 showed a temporal process at the left side measuring 8 cm x 5 cm and well circumscribed with a thin wall. This process extended towards the parapharyngium area through the foramen lacerum. The exocranial part measured 4 cm in diameter. The density of the process strongly suggested a mature dermoid cyst with fatty and calcium components. The histology study confirmed the diagnosis of dermoid cyst. The frequency of intracranial dermoid cysts is 2 to 3 times less than that of epidermoid cysts. This is an uncommon process accounting for 1% of intracranial tumors occurring in children. In the sustentorial spaces, the process occurs more frequently in the parasellar area. To our knowledge, exocranial extension has not been reported to date.

Laparoscopic management of ovarian dermoid cysts.

Benign cystic teratoma (dermoid cyst) was managed laparoscopically in 25 cases (16 cyst excisions and 9 oophorectomies). Surgical procedures to avoid spill during ovarian cystectomy and oophorectomy were developed (14 cases). This series demonstrates a gradual evolution in surgical technique. Surgical outcome was good in all cases, complications were rare, and the procedure required a hospital stay less than 24 hours.

Dermoid cyst of the floor of the mouth.

Dermoid cysts of the floor of the mouth are rare lesions thought to be caused by entrapment of germinal epithelium during the closure of the mandibular and hyoid branchial arches. They usually present as a nonpainful swelling. This type of lesion occurs more frequently in patients between 15 and 35 years, but can be seen in all age ranges. Histologically, all dermoids are lined by epidermis. The contents of the cyst lining determine the histological categories of the cyst: epidermoid, if epidermis is lining the cyst; dermoid, if skin annexes exist; or teratoid, if there are tissues derivated from the three germinal layers. Anatomical classification is useful for surgical approach choice, intra- or extraorally. This report presents a case of a dermoid cyst of the floor of the mouth in a 12-year-old patient, and a review of all steps necessary for its diagnosis and treatment was made.

Dermoid cyst in the posterior fossa accompanied by Klippel-Feil syndrome.

OBJECTS: Dermoid cysts accompanied by Klippel-Feil syndrome are uncommon, and the coincidence of these two rare diseases suggests an interesting idea about the pathogenesis of a dermoid cyst, which the authors consider with reference to an actual case. A posterior fossa dermoid cyst with dermal sinus and Klippel-Feil syndrome are reported in the same patient. A 23-year-old woman was admitted to hospital with progressive headaches. METHODS: Cervical radiography demonstrated C4-5 vertebral fusion, and magnetic resonance imaging revealed a large cystic mass in the midline of the posterior fossa. The cystic lesion was totally removed along with the accompanying dermal sinus. It was histopathologically diagnosed as a dermoid cyst. CONCLUSION: The rare coincidence of a dermoid cyst and Klippel-Feil syndrome suggests the possibility that a disturbance in the mesoderm before the fourth week of gestation might play an important part in the causation of dermoid cyst.

[Dermoid cyst of the nose].

Dermoid cyst of the nose may present difficult management problems if inadequately evaluated preoperatively or if incompletely excited. The most important is to differentiate them from nasal gliomas, meningocoeles et encephalocoeles. The Otolaryngological Clinic of Jagiellonian University in Cracow presented a review of the congenital midline nasal mass during 1945 and 1992 year. If a dermal fistule appears, it may be identified as a cutaneous defect leading from the midline of the nose. If this dermal fistule is connected with the skin of the nose it is called a dermal fistula dorsi nasi.

Nasal dermoid cysts in siblings.

Nasal dermoid cysts are congenital malformations which result from anomalous embryological development. Two cases occurring in siblings are presented. There have been several previous reports that the condition may be familial but in this report the initial suspicion of the milder anomaly in the younger child was raised primarily because of his older brother's history. This further report suggests that the incidence of familial occurrence of this anomaly may be greater than current literature suggests, and the possibility that other family members may be affected should be remembered by clinicians treating patients with this condition.

Ectopic beta-human chorionic gonadotropin production by a dermoid cyst.

Benign cystic teratomas of the ovary (dermoid cysts) are common in women in the 20- to 40-year-old age group; 10% of these teratomas are bilateral. There have been reports of hormone production by dermoid cysts, particularly thyroid-stimulating hormone. We report the first case to our knowledge, of ectopic human chorionic gonadotropin production by a dermoid cyst.

Intralingual dermoid cysts: a report of two new cases.

Dermoid cysts of the oral cavity are rare. When they do occur, the most common site is the floor of the mouth. Intralingual dermoid cysts are even more rare, and until now, there were only 15 such reports in the English-language literature. In this article, we describe two additional cases. Magnetic resonance imaging is extremely helpful in establishing a differential diagnosis. Surgical excision is recommended to correct deglutition and speech problems. Its rarity notwithstanding, dermoid cyst should be considered in the differential diagnosis of tongue masses in the younger population.

Congenital dermoid cyst of the middle ear.

Dermoid cysts of the head and neck are rare lesions comprised of epidermal and mesodermal elements. We report a dermoid cyst presenting in the middle ear of the youngest patient reported to date. Structures of endodermal descent were also identified, but, given that the entire middle ear mucosa is of endodermal origin, specific classification as a teratoma would be imprecise. This lesion is interesting in that it did not directly involve the mastoid. Possible embryologic sites of origin are discussed.

[Dermoid cyst in the fourth ventricle associated with Klippel-Feil syndrome].

Dermoid cysts in the central nervous system are often associated with various congenital disorders, especially dermal sinus and spina bifida. We report a case of dermoid cyst in the fourth ventricle associated with Klippel-Feil syndrome. A 47-year-old man with a long history of headache had been known to have a cystic lesion in the posterior fossa for 12 years. When he was referred to our hospital with complaints of transient tetraparesis, he showed bilateral cerebellar ataxia and minimal left hemiparesis. Furthermore, he was noted to have a webbed neck with a low hairline and facial asymmetry. CT and MRI showed multiple cerebral infarctions as well as a mass lesion in the posterior fossa. Cervical roentgenogram showed a fusion of C 2 and C 3 vertebrae. The tumor was totally removed via a suboccipital approach, and the diagnosis was a dermoid cyst. The present patient had not only dermoid cyst and Klippel-Feil syndrome but also hypertrophy of the zygomatic bone. The pathogenesis of the Klippel-Feil syndrome is presumed to be an intrauterine defect, with a failure of segmentation of mesodermal somites. The zygomatic bone is also derived from the mesoderm somites at early fourth week, too. From these points of view, the disturbance in the mesoderm before the fourth week of gestation might have played an important role in causing a dermoid cyst.

Multiple dermoid cysts within the same ovary: our experience of a rare case with review of the literature.

OBJECTIVE: Ovarian dermoid cysts are relatively frequent ovarian lesions that can be easily diagnosed by transvaginal ultrasonography. However, the recognition of multiple dermoid cysts, separated by normal ovarian tissue, within a single ovary is rare. CASE: We present a case with bilateral dermoid cysts, four dermoid cysts within the right ovary and one in the contralateral ovary. Transvaginal ultrasonography showed hyperechogenic areas in the right ovary with a hypoechogenic area in front of them; the hyperechogenic areas were separated by areas with the echogenicity of normal ovarian tissue and indentation, suggesting the presence of multiple dermoid cysts within the same ovary. CONCLUSION: Preoperative ultrasonographic suspicion of multiple dermoid cysts within the same ovary might contribute to a better decision about the surgical approach.

Familial hypercholesterolemia and intracavernous venous spilling of cholesterol in a child with large suprasellar dermoid cyst. Case report.

A unique case of suprasellar dermoid cyst and familial hypercholesterolemia in a child is reported. Such an association, which strengthens the congenital hypothesis of dermoid cysts, could be a manifestation of a complex dyslipidemic inherited syndrome, at least in children. Surgical removal of the dermoid cyst which spilled cholesterol into the cavernous and intercavernous sinuses, allowed reduction of cholesterol levels in the postoperative period.

Review of the literature and report of a case of a dermoid cyst.

This article presents a large dermoid cyst discovered in the floor of the mouth of a young male patient. The lesion was clinically detected by manual palpation and confirmed by the use of magnetic resonance imaging. Treatment of this case was by surgical removal of the dermoid cyst. The patient recovered without any complications or evidence of re-occurrence of the cyst.
