Orbital dermoid cysts located within the lateral rectus muscle.

BACKGROUND: Two patients, a 13-year-old girl and a 31-year-old man, had an orbital dermoid tumor located in the lateral rectus muscle. This unusual location of dermoid tumors has not been reported previously. METHODS: Computed tomography and magnetic resonance imaging showed a cystic mass within the belly of the lateral rectus in each patient. Surgical excision through a lateral orbitotomy showed a well-circumscribed mass surrounded by lateral rectus fibers. No periorbital attachment was noted. RESULTS: Results of histopathologic evaluations showed a dermoid cyst. Postoperatively, the diplopia and proptosis resolved. In one patient, an unusual subconjunctival deposition of fat droplets was seen. CONCLUSION: The findings in patients demonstrate an unusual presentation of dermoid cysts and make an addition to the differential diagnosis of enlarged extraocular muscles.

[Spontaneous rupture of intracranial dermoid cyst. Clinical and radiological study].

A 22 year old woman had a seizure, and the skull X-ray showed an intracranial arched calcification. CT scan permitted diagnosis of dermoid cyst. Rupture of the cyst was testified by low density areas disseminated on the cortical surface and intra-ventricular fat level. Surgical removal confirmed dermoid cyst with rupture and fat fluid inside. Authors underline infrequency of such intra-ventricular fat level. CT scan, with low density of lipidic origin promote considerably such diagnosis both of the real nature of the cyst and of its rupture.

[Laparoscopic conservative treatment of ovarian dermoid cysts].

Two methods for the laparoscopic dissection of dermoid ovarian cysts, less than 10 cm, in 55 fertile women, are compared. Water dissection was performed in 23 patients and bipolar scissors were used in 32 patients, creating a rhomb on the surface of the ovary, just to obtain a good traction for atraumatic dissection. The mean surgical time, complications and hospital stay have been compared. Operative laparoscopy is the technique of choice to remove most, if not all, ovarian dermoid cysts. It is suggested to use particular strategies in order to safely and easily dissect in toto the cysts.

Endoscopic removal of dermoid cysts of the eyebrow in pediatric patients.

Direct excision of dermoid cysts of the brow may lead to a prominent facial scar. These scars can be completely avoided with an endoscopic temporal approach that places the incisions in the hair-bearing portion of the scalp. Over the past 10 years, this approach was offered to every pediatric patient with a cyst in the area of the brow, and outcomes were favorable. The operative technique and results in 8 consecutive patients are reviewed.

Dermoid cysts of the floor of the mouth and lateral neck.

Dermoid cysts of the floor of the mouth and submandibular area represent an unusual clinical entity. We present three such cases and review their clinical presentation and pathologic classification. This study stresses the importance of recognizing and excising any tract leading from such cysts to the midline mandible or hyoid, in order to avoid a recurrence, since these tracts may be epithelialized.

[Dermoid cyst of the testis].

The article reports a case of dermoid cyst of the left testis in a 18-year-old young man. The cyst contained masses of fat, a great number of hairs, multilayer squamous epithelium. The cyst was removed with preserving 1/2 of testicular parenchyma. The examination 3 years after the operation found no local recurrence, the spermogram was normal. 10 literature cases are analysed. Basing on these 10 cases, available in Russian medical literature, and one own case, the authors analyse clinical, diagnostic and therapeutic aspects of dermoid testicular cysts.

[Dermoid cysts of the greater omentum (author's transl)].

The occurrence of dermoid cysts of a complex type in the greater omentum has been discussed. In report of a case the matrix of tumor originates from the supernumerary ovary of otherwise normal adnexa, and becomes implanted in the greater omentum by autoamputation as a result of peduncle torsion. This is an observation which contributes to the explanation of the histogenesis of teratomic cysts in the greater omentum.

Peritoneal "melanosis" associated with a ruptured ovarian dermoid cyst: report of a case with electron-probe energy dispersive X-ray analysis.

A case of peritoneal "melanosis" due to a ruptured left ovarian dermoid cyst is described. Histology showed that the dermoid contained gastric mucosa associated with ulceration, necrosis, and hemorrhage. The areas of pigmentation within the dermoid, omentum, and peritoneal cavity were due to collections of heavily pigment-laden macrophages. The pigment lacked the histochemical features of either melanin or hemosiderin, but electron-probe energy dispersive x-ray analysis showed that the pigment contained a high concentration of iron. It is postulated that peptic ulceration with hemorrhage is the most likely source of the pigment and that the peritoneal pigmentation is secondary to spillage of the contents of the dermoid cyst.

Unusual contents of a dermoid cyst of the ovary removed by laparoscopy.

Benign cystic teratoma (dermoid cyst) of the ovary is a common pathological entity. Usually, the cyst contains representative tissues of the 3 embryonic germ cell layers: ectoderm, mesoderm and endoderm. Sebaceous material, hairs, cartilages, teeth, even thyroid tissue are frequently observed. In this case, the tumour was a well-formed jaw and tongue, and was successfully removed via the laparoscope.

Orbital nodular fasciitis simulating a dermoid cyst in an 8-month-old child. Case report and review of the literature.

PURPOSE: To report a clinicopathologic correlation of orbital nodular fasciitis that simulated a dermoid cyst in an infant and to review the literature on orbital nodular fasciitis. METHOD: Case report; literature review. RESULTS: A progressively enlarging subcutaneous mass superotemporal to the right eye that clinically resembled a dermoid cyst developed in an 8-month-old boy. Magnetic resonance imaging disclosed an enhancing, circumscribed, solid, soft-tissue mass in the anterior part of the orbit superotemporally. The tumor was removed intact by a superolateral orbitotomy. Histopathologic and immunohistochemical studies revealed findings consistent with nodular fasciitis, a pseudoneoplastic lesion marked by a proliferation of myofibroblasts. CONCLUSIONS: Although nodular fasciitis in the ocular region usually occurs in adults and older children, it should also be considered in the differential diagnosis of orbital or adnexal masses in infants.

[Early diagnosis of dermoid cysts in the treatment of sterility].

Two cases of occult dermoid cysts in sterility patients were reported. In one case the follicular puncture during a gamete intra fallopian transfer (GIFT) trial led to diagnosis, in the other case it has been argued by sonography. Early diagnostic and subsequent therapeutic possibilities were discussed.

Ruptured spinal dermoid cyst with chemical arachnoiditis and disseminated intracranial lipid droplets.

A 33-year-old man presented with a 3-month history of gradually progressive leg weakness. Spinal MRI and myelography with CT demonstrated an extensive intradural abnormality suggesting a diffuse inflammatory or neoplastic process. Only after cranial CT and MRI demonstrated lipid droplets was the diagnosis of a ruptured spinal dermoid cyst suggested. Subsequent laminectomy revealed a ruptured intradural dermoid cyst in the lumbar spine, with chemical arachnoiditis.

Dermoid cyst with crystalline inclusions in adjacent cortex: an ultrastructural study.

Dermoids are rare tumors of the central nervous system. So far, no electron microscopic studies of these tumors have been available. We describe the histology and ultrastructure of a dermoid cyst in a patient with situs inversus and discuss the relationship of keratin and aseptic meningitis, a well-known complication. Histological examination showed an epidermal matrix with 2-4 layers, a cyst containing keratin and debris, some hairs and sebaceous glands. In some areas, chronic inflammation had destroyed the matrix of the cyst wall. Gliosis of the adjacent brain parenchyma was evident, as were eosinophilic rod-shaped crystals. Electron microscopy revealed gliosis with Rosenthal fibers in brain parenchyma adjacent to the tumor capsule. Intracellular osmiophilic, crystalline inclusions were prominent within this area. Glial cells and neuropil were spared. No gross intracellular pathology was seen.

Proptosis with mastication: an unusual presentation of an orbital dermoid cyst.

A 25-year-old woman presented in 1973 with the complaint of proptosis of the left eye with mastication. A firm retrobulbar orbital mass was detected, and diagnosis of possible dermoid cyst was made. She was subsequently lost to follow-up. Computed tomographic (CT) scanning and surgical excision done in 1984 confirmed the presence of an orbital dermoid cyst communicating with the temporal fossa through a bony defect in the lateral orbital wall. We suspect that pressure by the temporalis muscle on the dumbbell-shaped cyst caused the proptosis with mastication.
