1/10. Solitary mucosal neuroma of the hard palate: a case report.Mucosal neuroma is rare neurogenic tumour that arises in the oral cavity as a component of multiple endocrine neoplasia type 2b (MEN 2b). We present the case of a histologically confirmed solitary mucosal neuroma of the hard palate in a 49-year-old woman with no other components of MEN 2b.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/10. Neurofibromatosis type 1 and masses of the appendix: a case report.BACKGROUND: Neurofibromatosis type 1 is an autosomal dominant disease with high penetrance, affecting 1:3,000 pregnancies. Meningiomas and other benign central nervous system tumors, such as ependymomas, are common features. CASE: A patient with neurofibromatosis underwent cesarean section due to intrauterine growth restriction and nonreassuring fetal heart rate patterns. Examination of the abdominal cavity and intestines revealed a large (diameter, 12 cm), rubbery, fibrin-coated appendicular mass. The appendix was removed, and pathologic analysis confirmed the diagnosis of neuroma of the appendix. CONCLUSION: The case stresses the importance of careful inspection and evaluation of the abdominal cavity during surgery on patients with neurofibromatosis for the detection of possible associated masses.- - - - - - - - - - ranking = 0.087521242995477keywords = cavity (Clic here for more details about this article) |
3/10. Benign neurogenic tumors of the oral cavity.Neurogenic tumors are rare in the oral cavity, particularly so when malignant. Traumatic neuroma, although usually included with neurogenic tumors, is a reactive process rather than a true neoplasm. neurofibroma and schwannoma derive from nerve fibers, the perineurium, the endoneurium and the neurolemmomal cells. They present histological differences. The neurofibroma may present in solitary and generalized types; the latter also known as neurofibromatosis or von Recklinghausen's disease of the skin. We here report typical cases of benign neurogenic tumors of the oral cavity.- - - - - - - - - - ranking = 6keywords = oral cavity, cavity (Clic here for more details about this article) |
4/10. pain and neuroma formation in Wallenberg's lateral medullary syndrome.We report a patient with a Wallenberg's lateral medullary syndrome in which pain was a prominent feature. This led to substitution of the original and correct diagnosis by that of a thalamic syndrome for which a prefrontal leucotomy was performed. The patient died some years later from a myocardial infarction and autopsy was performed. In the dorsolateral part of the medulla oblongata a cavity was found in which aberrant nerve fibres with neuroma-like formations could be seen. These fibres coursed along blood vessels, and penetrated from the surface of the medulla oblongata. On the base of the clinico-pathological correlations, it is conjectured that destruction of the lateral reticular formation cannot be the sole cause of the severe pain.- - - - - - - - - - ranking = 0.043760621497739keywords = cavity (Clic here for more details about this article) |
5/10. Neural tumors of the oral cavity. A review of the spectrum of benign and malignant oral tumors of the oral cavity and jaws.The clinical and histologic features of benign and malignant neural tumors of the oral cavity and jaws are reviewed. Some rarer histologic variants are mentioned. Particular attention is paid to the two syndromes involving neural tumors of the oral cavity, namely, neurofibromatosis and multiple endocrine neoplasia III. A previously unreported case of the latter is presented.- - - - - - - - - - ranking = 10keywords = oral cavity, cavity (Clic here for more details about this article) |
6/10. Surgery of the skull base.Tumors involving the base of the skull are often occult and may become quite large before detection is possible. Symptomology varies depending upon the nature of the tumor and its placement. These neoplasms have frequently been considered inoperable simply because of their location, but in recent years microsurgical technique and high speed air drills have allowed the modern temporal bone surgeon to gain improved access to the skull base. A wide variety of surgical approaches to tumors in this area have been described in the past 20 years: translabyrinthine, middle fossa, transcochlear, retrolabyrinthine, retrosigmoid, transpalatal-transclival, and through the jugular bulb. The purpose of this paper is to review the indications, complications, and results of each of these procedures in relation to specific tumors involving the skull base. case reports illustrate the diagnosis and surgical management of a variety of unusual neoplasms, including an extradural meningioma of the temporal bone and clivus, a low grade squamous cell carcinoma on the tegmen in a radical cavity, a large primary cholesteatoma, an osteoblastoma of the temporal and occipital bones, an XIth nerve neuroma in the jugular bulb area, and an osseous hemangioma involving the facial nerve at the geniculate ganglion.- - - - - - - - - - ranking = 0.043760621497739keywords = cavity (Clic here for more details about this article) |
7/10. neuroma of the facial nerve masked by chronic otitis media.The absence of facial twitching, weakness, or palsy makes the diagnosis of facial neuroma difficult. The authors report a case of neuroma of the horizontal portion of the facial nerve masked by the presence of a chronic ear. A woman with a long history of discharge and hypoacousia in her left ear presented with acute dizziness. Examination revealed grade 3 horizontal right nystagmus, left anacousia, and the appearance of an epitympanic cholesteatoma. Computed tomography (CT) was performed after the vestibular condition improved. The clinical diagnosis of chronic otitis media with cholesteatoma together with the radiologic finding of the mastoid and tympanic cavity completely occupied by soft tissue were enough to send the radiologist astray. The radiologic diagnosis confirmed that the bony destruction of the vestibule and lateral semicircular canal could be caused by a cholesteatoma. A neuroma of the horizontal portion of the facial nerve was discovered during surgery performed for the chronic ear. The postoperative study of the CT scans showed that there was no erosion of the malleus or incus, despite wide erosion of the vestibule and lateral semicircular canal. This finding would be enough to suggest the presence of pathology other than cholesteatoma. The patient refused exeresis of the neuroma. The authors recognize the difficulty in urging a patient to an operation that surely will result in worsening of the facial function. Follow-up in this case has revealed no change in tumor dimension or facial function over 3 years.- - - - - - - - - - ranking = 0.043760621497739keywords = cavity (Clic here for more details about this article) |
8/10. Preoperative diagnosis of intratemporal facial nerve tumor: high-resolution CT and otoscopic findings in 4 cases.Four cases of facial nerve tumor were treated in our clinic during the past 16 years, one of which was a recurrence 12 years after the resection. Another case presented with relapsing facial palsy of sudden onset. The others presented with slowly progressive facial palsy. In each of the four cases, the horizontal and vertical portions were included in the tumor extension, and a mass was revealed in the posterior tympanic cavity by use of otoscopy. High-resolution CT, performed in all but the earliest case, proved to be the most valuable diagnostic tool, indicating the anatomical correlation of the tumor with the facial canal. With the diagnosis preoperatively established, facial reanimation procedure could be applied immediately after the tumor resection except in the recurrent case.- - - - - - - - - - ranking = 0.043760621497739keywords = cavity (Clic here for more details about this article) |
9/10. Multiple mucosal neuroma (MMN) or multiple endocrine neoplasia (MEN) type 3 syndrome. Ocular manifestations: a case report.Case report of a young man showing neuromas of the palpebral and bulbar conjunctiva and markedly thickened nerve fibers in both cornea. Multiple neuromas were seen on the lips and in the oral cavity. A medullary carcinoma of the thyroid was found. These symptoms pointed to the diagnosis of a MMN or MEN type 3 syndrome. There were no signs of phaeochromocytoma, however, which also belongs to this syndrome. The ophthalmologist, who may be the first to see such a patient as a child, should be aware of the malignancies which develop around puberty and of the strong and dominant heredity of this disease.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
10/10. Craniofacial access to the anterior and middle cranial fossae and skull base.A profusion of surgical approaches to gain access to the anterior and middle cranial fossa and skull base have been described. An attempt has been made to simplify the position by suggesting a classification of surgical approaches and to describe a standard approach (of at most 4 defined osteotomies, or at least 2) to give a craniofacial approach to the anterior and middle cranial fossae, the infratemporal fossa, the orbit and the superior nasal cavity. The full extent of the osteotomies have been likened to an ancient Corinthian face mask, or to the stylized face-mask worn by the comic book hero, Batman.- - - - - - - - - - ranking = 0.043760621497739keywords = cavity (Clic here for more details about this article) |
