Nasal dermoid cyst: diagnosis and management of five cases.

Five cases of nasal dermoid cyst are presented. Three out of five cases were settled during childhood. Three presented a mass with a hole on the external nose with recurrent local infections. One case was wrongly referred for a dacryocystitis. The first one was detected during an infection of the cerebral extension and frontal abscess was assessed by CT scan and MRI. Two patients had other associated congenital abnormalities: hypotrophy of the external ear in one case, multiples malformations in an other. Adequate exposure and cosmetic results are sometimes contradictory to define the best surgical approach. Dermoid cysts and sinuses must be completely removed to prevent recurrence. External rhinoplasty and bicoronal approach are the main procedures for removing these lesions.

Diagnosis of dermoid cyst of the floor of the mouth by fine-needle aspiration cytology: a case report.

A case of a dermoid cyst in the floor of the mouth in a 17-yr-old male is described. The diagnosis was made by fine-needle aspiration cytology and supported by histologic examination of the subsequently excised tissue. Dermoid cysts are benign lesions that can occur in the floor of the mouth. This case is presented to increase awareness of this entity and its occurrence in this location, and to demonstrate the feasibility of diagnosis by fine-needle aspiration. The cytologic and histologic features of dermoid cysts are described and discussed.

Congenital dermoid cyst of the anterior fontanelle in Turkish children--four case reports.

Four cases of congenital inclusion dermoid cysts located over the anterior fontanelle occurred in male Turkish children aged 6 months to 5 years. These rare cysts presented as slow-growing soft masses over the anterior fontanelle. The cysts were totally removed without recurrence. Dermoid cysts can be easily cured because of the absence of intracranial extension.

Supratentorial dermoid cysts. Presentation and management of five cases.

Five patients with supratentorial dermoid cysts who were surgically treated are presented. There were three males and two females, between the ages of 17 and 35 years (mean 26.6 years). The tumor location was frontobasal and/or temporobasal. The duration of illness before the diagnosis ranged from 1 to 14 months (mean 7.4 months). Clinical presentation included seizures, intracranial hypertension syndrome, aseptic meningitis, homonimous lateral hemianopsia, and memory defect. Preoperatively, all patients were investigated by computerized tomography (CT); in two cases, magnetic resonance (MR) imaging was also obtained. Tumor removal was performed by microsurgical procedures; it was total in 3 cases and subtotal in the remaining 2 cases. Histologically, all of the tumors exhibited the typical dermoid cyst pattern. There were no operative deaths. Two patients experienced postoperative language dysfunction and/or hemiparesis. No patient developed clinicoradiological evidence of tumor recurrence at 1 to 10 years (mean 5 years) following surgery. These results are discussed in light of the data previously reported by the literature.

Case report. Transient cerebral ischemia as a manifestation of ruptured intracranial dermoid cyst.

Transient cerebral ischemia was the initial manifestation of a ruptured intracranial dermoid cyst in a young adult male. The ischemia could have resulted from vasospasm caused by release of the contents of the dermoid cyst into the subarachnoid space or from other local effects of the tumor. The role of computed tomography in the evaluation of patients with transient cerebral ischemia is discussed.

Stroke related to a dermoid cyst: case report.

OBJECTIVE AND IMPORTANCE: We report the case of a woman presenting with sudden neurological deficit, revealing a parasellar dermoid cyst. To our knowledge, this clinicopathological finding is the first reported in the literature. CLINICAL PRESENTATION: A neurological examination of the patient revealed a left hemiparesis, including central facial palsy, which hampered her speech. The well-documented neuroradiological work-up (including computed tomography, magnetic resonance imaging, and magnetic resonance angiography) demonstrated right frontorolandic ischemia caused by a right supra- and parasellar dermoid cyst leading to middle and anterior cerebral arterial stenoses. INTERVENTION: Surgical intervention, using a right subfrontopterional approach, was successful. Complete dermoid cyst removal was achieved. The mechanism of the arterial stenoses is extensively discussed and is thought to result from an inflammatory reaction of the basal vessels. CONCLUSION: The patient recovered fully. Nevertheless, postoperative magnetic resonance imaging confirmed cerebral infarction.

Presacral dermoid cyst with scanty fat component: usefulness of chemical shift and diffusion-weighted MR imaging.

We present a case of a dermoid cyst located at the presacral space. Although CT and conventional MR (T1- and T2-weighted images) demonstrated a non-specific cystic mass with little evidence of calcification or fat, chemical shift and diffusion-weighted MR imaging suggested the presence of small amount of fat and abundant keratinoid substance within the tumor, respectively. Pre-operative diagnosis of dermoid cyst was made. The tumor was surgically resected and the diagnosis was confirmed. Chemical shift and diffusion-weighted MR imaging are useful in the diagnosis of dermoid cyst with little evidence of calcification and fat.

Endoscopic treatment of dermoid cyst.

Seven cases of benign cystic teratoma (dermoid cyst) were managed laparoscopically (six cyst excisions and one adnexectomy) using a surgical procedure to avoid spillage. Outcome was good in all cases without any complications.

Median dermoid cyst.

This report describes a median sublingual dermoid cyst in a 25-year-old male. These cysts are uncommon in the head and neck region, and rare in the floor of the mouth. The cyst was enucleated intact through a mid-line saggital incision in the floor of the mouth, and healing was uneventful. Histological examination, revealing that the cyst wall contained skin appendages, smooth muscle, and a lining of orthokeratinised stratified squamous epithelium, confirmed the diagnosis.

[Dermoid cyst of the ovary. False positive diagnosis in iodine 131 scintigraphy of differentiated thyroid cancers].

BACKGROUND: Total body 131-iodine labeled scintiscan is used to screen for residual tumoral tissue after ablation of differentiated thyroid carcinoma. At therapeutic doses, radioactive iodine can also be used for treatment. Thyroglobulin level, usually undetectable a few months after total thyroidectomy and metabolic irradiation with 131-iodine in patients without initial metastases, is absolutely necessary for interpreting the scintiscans. Iodine uptake occur in dermoid cysts which usually contain thyroid tissue. CASE REPORT: A 44-year old woman underwent total thyroidectomy with node dissection for papillary carcinoma of the thyroid with a vesicular architecture. Four months later, the total body 131-iodine scintiscan demonstrated a round zone of uptake in the pelvic area. The lesion was found to be a typical dermoid cyst. No thyroid or tumoral tissue could be demonstrated. DISCUSSION: Dermoid cysts can be the cause of false positive 131-scintiscans in patients followed after resection of differentiated thyroid carcinoma. Unlike previously reported cases, the dermoid cyst in this patient was totally devoid of thyroid tissue.

Orbital dermoid cyst.

Over a thirteen year period forty patients underwent surgery to remove an orbital dermoid cyst. Cysts which became manifest after the age of three years were deeper and larger than most that were noted before that age. Three out of four epidermoid cysts appeared after the age of 17 years and had an intracranial component. The majority of cysts showed histological evidence of leakage and associated inflammation. It is our view that dermoid cysts should be totally excised because they gradually enlarge and cause inflammation and scarring in adjacent structures.

Doppler flow characteristics of dermoid cysts: unique appearance of struma ovarii.

The purpose of our study was to evaluate the Doppler flow characteristics of ovarian dermoid cysts. In 70 women (mean age, 38.7 +/- 14.6 years), 78 ovarian lesions with mean diameter of 48.9 +/- 28.4 mm and preoperative sonographic diagnosis of dermoid cyst of the ovary were evaluated prospectively by Doppler flow sonography; these cysts were eventually removed surgically. The findings were compared to the postoperative histologic results. In 74 lesions (eight cases were bilateral), when blood flow patterns were detected (detection rate of 24.3%) they were obtained only from the ovarian tissue surrounding the dermoid cavity, with a mean resistive index of 0.6 +/- 0.1 (range, 0.4 to 0.76). In four cases, which were proved postoperatively to be struma ovarii, blood flow was detected not only from the cyst capsule but also from the centrally positioned solid area (dermoid tissue), with a mean RI of 0.565 +/- 0.08 (range, 0.509 to 0.667). Dermoid cysts of the ovary are devoid of blood flow, with flow detection rate being only 24.3% from the cyst capsule. When apparently vascularized solid tissue is detected in the central part of a sonographically suspected benign cystic teratoma, struma ovary is highly suspected.

[X-ray computed tomographic aspects of dermoid cysts of the ovary].

155 patients with 210 ovarian tumours were examined pre-operatively by CT from December 1984 to February 1988. 27 patients had dermoid cysts, unilateral in 25 cases and bilateral in 2 cases. These cystic teratomas were benign in 26 patients. In one case, malignant transformation occurred. CT detected 29/29 tumours (100%). Presence of fat (26/29, 90%), calcification (20/29, 69%), Rokitansky protuberance (25/29, 86%), tufts of hair (20/29, 69%), or fat fluid level (4/29, 14%), allowed to make a definite diagnosis in 28/29 cases (96%). These findings and especially demonstration of fat, appeared to be specific for dermoid cysts in our series. The diagnosis of torsion of the cyst associated with torsion of the adnexa was made in 2 patients. No abdomino-pelvic extension occurred in 26/26 patients presenting with a benign dermoid cyst and CT correctly diagnosed the lymph node and hepatic spread in the single case of cancer.

The management of dermoid cysts--a comparative study of laparoscopy and laparotomy.

The aim of our study was to compare laparoscopy with laparotomy for the removal of ovarian dermoid cysts. Thirty-eight women with benign ovarian dermoid cyst were allocated for either laparoscopy (18 patients) or laparotomy (20 patients). The two groups were compared for operative and hospitalization times and postoperative course. Operating time was longer (93.6 +/- 23.8 min) and hospitalization time significantly shorter (22.4 +/- 6.6 h) in the laparoscopy group. No complications were reported in either group. We conclude that operative laparoscopy is a safe procedure for the removal of dermoid ovarian cysts and is as effective as laparotomy.
