[A case report of a scalp dermoid cyst containing watery-clear fluid].

We report a case of a 7-month-old female with a dermoid cyst on the anterior fontanelle. She was born with a vacuum extractor. Two weeks later, her scalp on the anterior fontanelle bulged. A doctor was consulted when she was 3 months old, because the tumor was enlarging. Magnetic resonance image (MRI) showed a cystic mass on the anterior fontanelle. She was brought to our institute. At the first medical examination, she was alert and had no neurological deficit. The tumor was suspected to be a sinus pericranii or a pseudo meningocele. She was observed as an out patient, but the tumoral size become more enlarged. When she was seven months old, we punctured the cystic tumor and the tumor collapsed. But, two weeks later, it enlarged again. The cystic fluid was watery clear and the composition differed from cerebrospinal fluid (CSF). The tumor was resected totally. The histological examination revealed a dermoid cyst which involved ducts of the eccrine glands and folliculi pili. The cystic fluid was thought to be secreted from the eccrine glands.

Squamous cell carcinoma arising in a dermoid cyst of the ovary.

BACKGROUND: Unlike ordinary germ cell tumors of the ovary, squamous cell carcinoma arising in a dermoid affects elderly persons. Prognosis is poor when the disease has spread beyond the ovary. CASE: The case of a 67-year-old woman with stage III squamous cell carcinoma arising in a dermoid cyst of the ovary and extending to the serosa and myometrium of the uterus, pelvic peritoneum, the serosa, and muscularis of the distal ileum and penetrating entirely through the wall of the sigmoid is presented. She underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, partial small bowel resection with anastomosis, partial colectomy with anastomosis, and excision of tumor from the pelvic peritoneum. She was treated with six cycles of Taxol and cisplatin chemotherapy at monthly intervals. She has remained disease-free for over 4 years. CONCLUSION: This is the fourth report of a prolonged disease-free survival of a patient with stage III squamous cell carcinoma arising in a dermoid cyst of the ovary. This result is encouraging, but the best treatment for advanced cancer of this type has yet to be determined.

Fine-needle aspiration of dermoid cyst of the pancreas: a case report.

A 53-yr-old woman presented with a left upper quadrant abdominal mass attached to the body of the pancreas. Fine-needle aspiration (FNA) yielded cyst fluid containing numerous benign, mature squamous cells, keratin debris, and inflammatory cells. The diagnosis of dermoid cyst was subsequently rendered on the resected specimen. The cytologic and histologic features are presented. FNA cytology proves to be a valuable diagnostic adjunct in the preoperative evaluation of a patient with dermoid cyst of the pancreas.

Dermoid cyst within an upper thoracic meningocele.

A case of dermoid cyst within an upper thoracic meningocele is reported. The incidental feature of this combination is extremely rare. As upper thoracic meningocele is often associated with other spinal and intracranial abnormalities, close observation and radiologic evaluation of the craniospinal axis are necessary to obtain an exact diagnosis and to achieve an appropriate treatment.

Congenital inclusion dermoid cyst located over the region of the anterior fontanel in adult Nigerians: report of two cases.

Two cases of a congenital inclusion dermoid cyst located over the region of the anterior fontanel are described in adult Nigerians, aged 28 and 32 years. In both cases, the cystic lesion was noticed at birth over the anterior fontanel as a small soft lump, and was carried on the head from infancy into adult life. The clinical, radiological, and the operative findings revealed no intracranial extension. The two lesions were histologically verified as dermoid cysts. Surgical excision was curative.

Congenital inclusion dermoid cysts of the scalp.

The natural history of congenital inclusion dermoid cysts of the scalp is unknown. We report three cases of this condition, which has been followed from birth for up to ten years. Dermoids are congenital subcutaneous cysts, which gradually flatten and scar over a number of years. The lesions are covered with skin showing focal alopecia but they may be surrounded by a collar of hypertropic hair. Later in life flattened cysts may be mistaken for aplasia cutis, but the history of a cyst at birth allows the clinician to distinguish these two conditions. As these cysts have a potential for intracranial extension, this is an important clinical entity.

[Dermoid cyst of the lateral ventricle associated with ethmoidal dermal sinus. Report of a case].

We report a case of a ventricular dermoid cyst associated with a dermal sinus connected with the ethmoidal cells in a patient who developed rapid symptoms of raised intracranial pressure. Computed tomography showed a cystic mass in the right lateral ventricle with a hydrolipidic image in the left frontal horn of the ventricle and associated hydrocephalus. Magnetic resonance imaging showed a heterogeneous T1 hyperintense mass with a fistulous tract communicating with the ethmoid cells. A cerebrospinal fluid ventriculo-peritoneal shunt was initially established, which required further revision. A right sided transventricular approach was undertaken in a second stage, allowing resection of a dermoid cyst. Obliteration of the dermal sinus tract was obtained using pericranial duraplasty. Clinical and imaging features are discussed. The need for total resection including the tumor capsule and occlusion of the fistula are emphasized if recurrence and infection are to be prevented.

[Demonstration of plasmacytes in gingival immune defense units in dermoid cysts of the ovary].

Gingival units of immunological defense have been observed surrounding erupted teeth in the connective tissue of the wall of ovarian dermoid cysts. Using a modified immunoperoxidase technique, the production of IgA, IgG and J chains has been clearly detected. This technique works perfectly on decalcified specimens. Since dermoid cysts are not contaminated, the origin of the plasma-cells in these units is presumed to be triggered by other antigenic factors. These are present in epithelium and provided a possible explanation for the "homing" of lymph-cells migrating from the immune system.

Current trends in the surgical management of orbital dermoid cysts among pediatric ophthalmologists.

PURPOSE: To survey the membership of the American Association for Pediatric Ophthalmology and Strabismus on their preferences in the management of dermoid cysts. METHODS: The 689 active members of the American Association for Pediatric Ophthalmology and Strabismus were surveyed by mail on their preferences in the management of dermoid cysts. The survey addressed use of imaging, timing of surgery, surgical approach, use of corticosteroids, and satisfaction with results. RESULTS: Of the 689 members surveyed, 62.4% responded. Of these, 75.8% performed orbital dermoid excisions in their pediatric ophthalmology practices. Imaging was always obtained by 9.5%, never obtained by 9.5%, and obtained for specific reasons by 81.0%. Computed tomography scan was the preferred imaging modality of 66.2% of respondents. Surgery was deferred until older than 6 months by 68.9%, and 71.9% cited anesthetic risk as the reason for waiting. Surgical approaches used were sub-brow incision only (53.9%), eyelid crease incision only (15.8%), or either (22.6%). Ninety-six percent of respondents never used adjunct corticosteroids, and 99.2% of respondents were satisfied with their surgical results. CONCLUSIONS: The majority of American Association for Pediatric Ophthalmology and Strabismus members defer orbital dermoid surgery until 6 months of age due to anesthesia risk, use the sub-brow incision, and obtain imaging only for specific reasons. Most respondents never use systemic corticosteroids at the time of surgery, and are satisfied with their results.

An unusual presentation of neck dermoid cyst.

Congenital masses are the most common non-inflammatory neck lesions in children. Although usually present at birth, they can appear at any age. Dermoid cysts are benign lesions of congenital origin usually presenting as a midline neck mass. They rarely appear in the lateral region of the neck. Lateral cervical dermoid cyst is presented as a rare, unusual case, and differential diagnosis and management are discussed in light of recent literature.

Mucoepidermoid variant of adenosquamous carcinoma arising in ovarian dermoid cyst: a case report and review of the literature.

A 40-year-old woman with mucoepidermoid variant of adenosquamous carcinoma arising in dermoid cyst in left ovary is presented. The patient was staged as IC. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymph node sampling were carried out. The disease recurred in postoperative 12th month. To our best knowledge, this is 12th case of adenosquamous carcinoma in dermoid cyst and third case of mucoepidermoid variant of adenosquamous carcinoma in the literature.

[Secondary cancers arising in mature benign cystic teratomas of the ovary (dermoid cysts). Review of the literature apropos of a new case].

No new general review has appeared concerning the malignant changes that can occur in dermoid cysts of the ovary since the works of Peterson in 1957 and Climie and Heath in 1968. A personal case of epidermoid carcinoma--Stage II B--which occurred in a dermoid cyst gave us the opportunity of reviewing the 132 cases published between 1968 and 1985, which bring the total cases published to more than 400. The cancer arises in 1.78% of mature cystic teratomas. The mean age at diagnosis is 53 years and this pathological change is found five times more frequently after than before the menopause. Before laparotomy is carried out there is no clinical sign nor paraclinical evidence of the diagnosis over and above that of a benign cyst. There are all kinds of histological changes but the epidermoid carcinomas occur in 75% of cases. The survival rate for this kind of ovarian tumour is very poor, with 27% survival after 3 years, taking into account all states and all histological types. Epidermoid carcinomas seem to have a better prognosis than other histological types, and an important prognostic feature is the spread and the ability to remove the tumour surgically when it has extended beyond the capsule of the ovary. Although it is not easy to lay down the best therapy for this condition, by and large extended surgery followed by polychemotherapy or radiotherapy are apparently the only ways of improving the poor prognosis for these tumours.

Peptide tyrosine tyrosine-positive ovarian carcinoid tumor arising from a dermoid cyst.

A case of ovarian carcinoid tumor of the trabecular type is presented. The small carcinoid tumor was found incidentally in a resected dermoid cyst. Histologically, the tumor was surrounded by a smooth muscle layer with focal stromal invasion. Non-carcinoid papillary mucosa and a few small glands, simulating the mucosa of the fallopian tube and remnant müllerian glands, respectively, were also present adjacent to the carcinoid tumor and enclosed by the same smooth muscle layer. The tumor cells revealed argyrophilia, and were positive for peptide tyrosine tyrosine (PYY) in the cytoplasm and for CEA in part of the luminal surface. This case was considered to be a rare ovarian carcinoid tumor arising from a dermoid cyst, without association of struma ovarii. PYY may be a potential marker for determining the histogenesis of ovarian carcinoid tumors.
