Chordomas are maligaant tumors which arise in the remnants of the embryonic notochord, and exhibit a definite predilection for the extremes of the spinal axis, the great majority arising either in the basioccipital or in the sacrococcy geal regions. Particularly, complete surgical removal is almost impossible, therefore, local recurrence after the surgical removal of this tumor is common or rule. This report describes a csse of chordoma arising sacrococcygeal region treated with block resection.

Sacrococcygeal teratoma should be differentiated from low-lying meningocele or anteriorly-locating meningocele in sacral region in neurosurgical field. The authors present a case of sacrococcygeal teratoma in 1 5 day-old girl.

Chordomas arise mainly in the sacrococcygeal region, and to a lesser extent, in the spheno-occipital region. When occurring in the latter region, they may protrude into nasopharynx and rarely into the sinonasal tract, mainly sphenoid sinus. Histologically, the vacuolated physaliphorous cell is pathognomonic. This tumor is histologically benign but locally aggressive and often far advanced at the time of presentation. The current treatment is applying surgical excision with/without postoperative radiation. Since its first report in 1987, there have a several reports of primary nasopharyngeal chordoma throughout the world. In Korea, one case of sphenoidal chordoma was reported in 1993, but there had been no report of primary nasopharyngeal chordoma. We report a recent case of primary nasopharyngeal chordoma we have treated by transnasal endoscopic surgical excision and present a review of the literature.

Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.

Chordomas are benign tumors that are thought to originate from remnants of notochord. They develop in the sacrococcygeal region but rarely form in the sellar region. Clival chordomas are benign tumors but because of their critical location, local invasion, recurrence, and occasional metastatic spread and their prognosis is similar to that of malignant tumors. The conventional transcranial approach is a treatment with high surgical morbidity. But transsphenoidal approach is a less invasive method with reduced surgical morbidity and complications. We report two cases of chordoma arising from the clivus treated by a transsphenoidal approach.

STUDY DESIGN: Case report OBJECTIVES: We report a case of relatively rare multiple bilateral perineural cysts. SUMMARY OF LITERATURE REVIEW: Tarlov cysts, also known as perineural cysts are most often found in the sacral region, but there are a few cases reported in the thoracic region. In particular, there are very few cases of multiple bilateral thoracic perineural cysts. MATERIALS AND METHODS: A woman aged 65 years with perineural cysts in the bilateral T10-T11 and T11-12 neural foramens, underwent a T10-11-12 decompressive laminectomy and resection of the cyst. RESULTS: Satisfactory results were obtained for the patient after surgery. CONCLUSIONS: For more detailed and definitive treatment of thoracic perineural cysts, additional cases are required.

A tailgut cyst is a rare congenital abnormality located in the retrorectal space and is usually manifested during childhood or adulthood. We report the MR, CT and ultrasound findings of a tailgut cyst in a 23-day-old neonate.

Spinal meningiomas are most commonly found in the thoracic sections while it is extremely rare in the cervical, lumbar and sacral regions. In Elsberg's series, there were 10 cervical, 59 thoracic and 4 lumbar ; none below the 3rd lumbar segment. Recently, we encountered a case of cauda equina meningioma and was completely extirpated with no remnants of any neurological deficits.

Essential hyperhidrosis is a socially disabling and emotionally embarrassing condition. Localized excessive sweating in the sacrococcygeal region is a rare form of focal hyperhidrosis. Although numerous treatment options exist, including botulinum toxin and sympathetic neurolysis, there has been no generally accepted form of treatment. The following cases describe the successful reduction of excessive sweating in the sacrococcygeal region, without side effects, after local applications of topical glycopyrrolate and the use of fast drying clothes.
