1/98. Endoscopically assisted anterior cranial skull base resection of sinonasal tumors.The traditional approach to sinonasal tumors involving the base of skull has been the anterior craniofacial resection. Endoscopic techniques have created the potential to approach the intranasal aspect of skull base lesions without external incisions and still develop an en bloc resection when removed. We report our initial experience with skull base neoplasms in which the otolaryngic portion of the standard resection was accomplished instead through an endoscopic approach. The nature of lesions favorable for this approach and associated technical issues are discussed. Although we do not consider this approach a replacement for the traditional anterior craniofacial resection, it is an important adjunct in the skull base surgeon's armamentarium.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/98. Complete dentures and the associated soft tissues.Some of the conditions of the soft tissues related to complete dentures encountered during a period of 25 years at a university clinic were presented and discussed from the standpoint of the clinical prosthodontist. During this time, over 1,000 denture patients were treated each year. For some conditions, a method of management was offered with treatment by sound prosthodontic principles rather than unneccessary medication. That denture fabrication involves much more than mere mechanical procedures is an understatement. Complete dentures are foreign objects in the oral cavity that are accepted and tolerated by the tissue to a degree that is surprising. As prosthodontists, we can gain satisfaction from the realization that the incidence of oral cancer due to dentures is less than extremely low. At the same time, we must be ever mindful of the statement by Sheppard and associates. "Complete dentures are not the innocuous devices we often think they are." Every dentist must remember that one of his greatest missions is to serve as a detection agency for cancer. The information discussed indicates (1) the need for careful examination of the mouth, (2) the value of a rest period of 8 hours every day for the supporting tissues, and (3) the importance of regular recall visits for denture patients. Robinson stated that while the dental laboratory technician can be trained to aid the dentist in the fabrication of prosthetic devices, his lack of knowledge of reactions and diseases of the oral tissues limits him to an auxiliary role. Complete prosthodontics is a highly specialized health service that greatly affects the health, welfare, and well-being of the patient. It can be rendered only by the true professional who is educated in the biomedical sciences.- - - - - - - - - - ranking = 0.11341165867157keywords = soft (Clic here for more details about this article) |
3/98. A case of squamous papilloma after uvulopalatopharyngoplasty.We report the case of an adult who developed an isolated-solitary papilloma on the margin of the soft palate 1 month after he had undergone a uvulopalatopharyngoplasty. We describe the clinical and cellular characteristics of this common lesion.- - - - - - - - - - ranking = 0.022682331734314keywords = soft (Clic here for more details about this article) |
4/98. Recurrent lacrimal sac papilloma: case report.Tumors of the lacrimal sac are rare. Benign papillomas comprise approximately 40% of all neoplasms of the lacrimal drainage system. They often present insidiously with symptoms of dacryostenosis or dacryocystitis. Recurrent bouts of dacryocystitis and nasolacrimal duct obstruction were reported in a 35-year-old man over a period of 13 years. A medial canthal mass was noted in the 6th year after the onset of symptoms. A tumor was discovered incidentally during surgical intervention for presumed dacryostenosis. Surgical removal of the tumor and dacryocystorhinostomy were performed. The histopathologic report turned out to be benign papiloma. Local recurrences occurred during the follow-up period. In addition to surgical excision, we applied cryotherapy and CO2 laser to prevent further recurrence. This case we presented the characteristic recurrence of lacrimal sac papilloma and implied the possibility of tumor occurrence in a patient with recurrent dacryocystitis. We must bear in mind that a recurrent dacryocystitis may be a presentation of a lacrimal sac tumor, because early diagnosis and aggressive treatment can prevent recurrence and result in a cure.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/98. Epidermal nevus syndrome with development of a mandibular ameloblastoma.Epidermal nevus syndrome (ENS) is a hamartoneoplastic syndrome characterized by the association of epidermal nevi with abnormalities in other organ systems. We report a 32-year-old woman with ENS that, in addition to cutaneous manifestations, showed red plaques on the maxillary and mandibular labial alveolar mucosa and a papillomatous lesion of the midline posterior hard palate. Radiographic examination of the jaws was noncontributory. Approximately 5 years later, a follicular ameloblastoma developed in the mandible. The tumor showed duct-like cystic spaces, continuity with the overlying epithelium, and globular myxomatous areas in the connective tissue. The palatal lesion was diagnosed as papilloma, whereas the maxillary plaques showed nonspecific mucositis. The association of ameloblastoma with ENS is discussed. This is the second case of ENS associated with ameloblastoma reported in the medical literature.- - - - - - - - - - ranking = 0.16860901372322keywords = connective (Clic here for more details about this article) |
6/98. Juvenile papillomatosis of the breast in a 9-year-old girl.Juvenile papillomatosis (JP) is a rare benign, proliferative breast tumor in children. We observed a 9-year-old girl with a large soft-tissue mass at the lower outer quadrant of the left breast. ultrasonography showed an ill-defined, inhomogeneous mass with numerous small, hypoechoic areas. The tumor was completely excised. Histopathology revealed JP of the breast. The case is presented and the literature is reviewed.- - - - - - - - - - ranking = 0.022682331734314keywords = soft (Clic here for more details about this article) |
7/98. Congenital unilateral benign papillomatosis of the mouth.A 29-year old man had an unusual unilateral lesion of the mucous membranes of the mouth, including the lips, buccal mucosa, hard and soft palate, and uvula. The lesion was a conglomerate of tiny papillomas and had been present since birth. At the age of 8 years, a mass extending from the uvula into the pharynx was surgically excised. The histopathological findings showed acanthosis, papillomatosis, and an inflammatory infiltrate. The findings represent a rare case and perhaps a unique one, to my knowledge.- - - - - - - - - - ranking = 0.022682331734314keywords = soft (Clic here for more details about this article) |
8/98. focal dermal hypoplasia: management of complex dental features.A 17 year-old female who presented for treatment of grossly carious lower first molar teeth had multiple features of focal dermal hypoplasia (FDH). These included enamel pitting and hypoplasia, anomalies of shape, size and positioning of teeth, as well as soft tissue papillomas and telangiectasis of tongue. A case report and a synopsis of the syndrome (FDH) are presented, the oral aspects of the condition are reviewed and the management of the complex dental anomalies is discussed.- - - - - - - - - - ranking = 0.022682331734314keywords = soft (Clic here for more details about this article) |
9/98. biliary tract papillomatosis.Papillomatosis of the biliary tract is characterised by multicentric papillary lesions of intra and extrahepatic biliary epithelium. It's a rare benign neoplasm of the biliary tract that causes obstructive jaundice with a high rate of malignant transformation. We described a case of papillomatosis of the biliary tract in a woman of 75-years-old, who came to our observation with jaundice, pruritus and fever. The surgical treatment consisted of cholecystectomy, choledochotomy and positioning a definitive T-Tube. We described our experience and the evolution of this disease.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/98. Malignancies arising in oncocytic schneiderian papillomas: a report of 2 cases and review of the literature.Oncocytic schneiderian papillomas (OSPs) are uncommon benign neoplasms that arise from the sinonasal schneiderian epithelium. Malignancies arising in OSPs are rare, and, to our knowledge, only 14 such instances have been reported in the medical literature. We report 2 additional cases--a small cell carcinoma and a sinonasal undifferentiated carcinoma arising in OSPs and presenting synchronously with the benign neoplasm. The potential for malignant transformation in OSPs is small, but warrants that these papillomas be completely excised to exclude a coexisting carcinoma.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
