We treated a patient with an ovarian tumor histologically consisting of an endometrial cyst, dermoid cyst and mucinous cystadenoma, in the same ovary. A comparative study between ultrasonic and histological findings was done. The usefulness, drawbacks and limitations in the ultrasonic evaluation of ovarian tumors are discussed.
Supratentorial dermoid cysts are rare lesions. In eight cases presented here, the lack of recurrence after subtotal removal of the capsule and the good long-term prognosis are emphasized. This finding is in agreement with the literature. The frequent relationship of these lesions with the cavernous sinus suggests a vascular genesis in the development of intracranial dermoid cysts.
Since ovarian dermoid cyst originates in parthenogenesis of the oocyte, it contains various kinds of tissues. Therefore, some tumor markers are expected to be positive. Clinical features of 174 pathologically confirmed dermoid cysts between Jan., 1985 and Aug., 1989 were reviewed, especially concerning tumor markers. The age of the patients was 11 years to 71 years (Mean 35.0 +/- 0.9 years). The weight of the dermoid cyst was 5g to 2.540g (mean 225.9 +/- 26.3g), while most of them were below 200g. The site of the tumors was similar on both the right and left. CA19-9 showed the highest positive rate of 45.5% (40/80). CA125 was second 12.7% (16/126) in markers with more than 20 examined cases, while the rate for AFP, Ferritin, CEA, LDH and TPA was 2.7% (3/110), 2.6% (1/38), 1.6% (2/128), 0.6% (1/161), 0% (0/24), respectively. SCC, IAP and beta 2-MG were examined in less than 20 cases and the positive rate was 18.8% (3/16), 9.1% (1/11) and 8.3% (1/12), respectively. There was no significant relationship between tumor weight and the CA19-9 concentration. In some cases, the serum CA19-9 concentration was followed up after the operation. The half life of CA19-9 was clinically estimated at 4.9 +/- 1.1 days.
Thyroglossal duct cysts and dermoid cysts are two distinct lesions which can occur in the midline of the head and neck region. Different embryologic explanations for these two lesions have traditionally been accepted. Recent evidence, however, hints at an association between them. We present here a case in which both of these cysts occurred together in an unusual anatomic location, along with a discussion of the possible relationship between these two pathologic entities.
Giant dermoid cysts of the orbit are developmental abnormalities that are usually found near the lacrimal gland in adults. The diagnosis of giant dermoid cysts can usually be established by radiographic studies and computed tomographic scanning. A surgical technique for the removal of these lesions with minimal complications is described in detail. Two cases are presented to demonstrate the methods used to diagnose and completely remove giant dermoid cysts with recovery of visual function and extraocular movements.
Multiple lesions associated with suprasellar dermoid cyst are well demonstrated preoperatively on computed tomography (CT) and magnetic resonance (MR) imaging. Although the presence of multiple fatty globules in ventricles and/or subarachnoid space has been thought to be evidence of ruptured dermoid cyst, there are no signs or symptoms, including operative findings, attributable to dermoid cyst rupture in our case. The distinctive CT and MR appearance is described and possible etiology of the multiple lesions is discussed.
A retrospective study of dermoid cysts in children over the past 13 years at St. Christopher's Children's Hospital of Philadelphia, showed that 37% of the dermoids in the body occurred in the orbital and peri-orbital areas. An unusually high percentage of these occurred in the left eyebrow which appears to be the most frequent location for dermoid cysts in children. Dermoid cysts are a very common lesion encountered by ophthalmologists inasmuch as 3.3% of all ophthalmic surgical procedures in children were performed for dermoids. All 231 cases in this series were benign. The manner and time of presentation of these lesions are discussed as well as the treatment.

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.
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.
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.
Intracranial dermoid cysts are usually reported to be associated with long lasting or waxing-waning symptoms. Computer tomography (CT) scans usually depict such neoplasms as well-defined areas of low density. This report is about a case of a dermoid cyst, the acute clinical features and CT hyperdensity of which mimicked a hematoma in the posterior fossa. The association of acute onset with CT hyperdensity makes this case of dermoid cyst very unusual.

We report on a 46-year-old man with a congenital nasal dermoid cyst that extended intracranially to form large bifrontal intraaxial dermoid cysts, which became secondarily infected through a nasal dermal sinus tract. Computed tomography demonstrated bilateral frontal lobe ring enhancing cystic masses containing fat-fluid levels consistent with dermoid cyst abscesses. Axial and coronal CT of the skull base and nose demonstrated a midline bony canal extending from two dimples on the dorsum of the patient's nose to the base of the anterior cranial fossa. The clinical, CT, and surgical findings are reviewed as well as the embryogenesis of congenital nasal dermoid cysts.
A subgaleal dermoid cyst of a 32 years old white adult is reported. The lesion appeared at the age of several years and ten regularly. Clinical examination, complementary exams as well as the result of the operation are reported. Embryology, histological classification and the main clinical, laboratory and histological characteristics of such lesions are defined by the review of the literature. Subgaleal dermoid cyst is rare in childhood and exceptionally occurs in adults. Only six cases of subgaleal dermoid cyst of adult are mentioned in the literature. Most of the time, the lesion is situated on the anterior fontanelle. The treatment is surgical and the prognosis is excellent.
Autopsy findings of primary malignant melanoma arising in an ovarian dermoid cyst in an 86-year-old woman are presented. The right ovary was replaced by a dermoid cyst, 14 x 9 x 9 cm in size, in which several nodular tumors with diameters less than 3.2 cm were localized. They comprised diffusely proliferating anaplastic cells with prominent nucleoli. Some of them contained melanin pigments in the cytoplasm. The tumor cells were positive for S-100 protein and ultrastructurally showed melanosomes. In addition, several benign pigmented lesions resembling dermal nevus, pigmented schwannoma, or cellular blue nevus were present in the dermoid cyst, one of which contained a malignant melanomatous component. Histologic transition between benign and malignant components and the presence of another small focus of atypical melanocytes in the benign lesion suggested that the malignant melanoma arose in close association with the previously existing benign pigmented lesions in the dermoid cyst.
39 cases of intraorbital dermoid cyst were examined by CT scanning with characteristic features of heterogeneity in the cystic content with areas of negative CT value, nonenhancement by contrast media, and excavation of the orbital walls. The precise localization of the tumor is conducive to the selection of a proper surgical approach.
