1/15. Giant cell angiofibroma of the oral cavity: report of a new location for a rare tumor.Giant cell angiofibroma is a rare, soft tissue tumor that was first described in the orbit. Since then, several case reports have described this tumor in a number of extra-orbital sites, suggesting a wider anatomic distribution than is generally recognized. The tumor typically acts in a benign fashion with only rare local recurrences but no tendency to metastatic disease. Here, we report the first case of a giant cell angiofibroma in the oral cavity. The tumor presented as a soft tissue nodule on the buccal mucosa of a 60-year-old man. The histologic differential diagnosis included a number of other uncommon soft tissue neoplasms, including giant cell fibroblastoma, solitary fibrous tumor, and pleomorphic lipoma. The histologic and immunohistochemical features of this tumor and differentiation from other histologically similar soft tissue neoplasms are briefly discussed.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/15. Giant cell angiofibroma of the buccal mucosa.We report a case of a patient with a recently described entity (giant cell angiofibroma) occurring in the oral cavity. A submucosal solid tumor arising in the right buccal mucosa of a 46-year-old woman was histologically characterized by a patternless spindle-cell proliferation within a generally myxoid stroma containing areas of perivascular sclerosis. Numerous multinucleated giant cells of the floret type were present. Immunohistochemically, the tumor cells and multinucleated giant cells exhibited positivity for CD34. To the best of our knowledge, this is the first report of a giant cell angiofibroma arising in the oral cavity.- - - - - - - - - - ranking = 0.4keywords = oral cavity, cavity (Clic here for more details about this article) |
3/15. Extranasopharyngeal angiofibroma arising from the nasal septum.Extra nasopharyngeal origin of angiofibroma is very rare. The nasal septum is a very rare site of extra nasopharyngeal angiofibroma with only two cases reported in the medical literature. We report here a case of a vascular mass arising from the nasal septum of an 8 year old boy. Histopathology confirmed it to be a case of angiofibroma. A review is also made of the other reported cases of angiofibroma arising from the nasal cavity. The likely theory of origin of the tumor and the management is also discussed.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
4/15. Juvenile angiofibroma: case report and the role of endoscopic resection.Juvenile angiofibroma is benign yet aggressive. Due to its inaccessible location in the nasopharynx, open surgery usually requires osteotomies which cause stunting of facial growth in adolescent males. Advances in imaging and treatment techniques have now facilitated more accurate staging of this disease. For small, extracranial tumours limited to the nasal cavity and paranasal sinus, endoscopic resection is a viable alternative. This case report will illustrate how endoscopic resection allows good control with minimal morbidity compared to open surgery or radiotherapy.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
5/15. Application of cyberknife for the treatment of juvenile nasopharyngeal angiofibroma: a case report.Juvenile nasopharyngeal angiofibroma (JNA) tumors can be locally destructive when they spread submucosally. The purpose of this study was to present an image-guided, robotic radiotherapy (Cyberknife) to successfully treat a 12-year-old boy with Juvenile nasopharyngeal angiofibroma (JNA). He complained of progressive right nasal obstruction, intermittent epistaxis. Computed tomography (CT), and magnetic resonance imaging (MRI) revealed the presence of a tumor in the right nasal cavity and nasopharynx with significant hypervascularization from the right maxillary artery. Pathological findings confirmed the diagnosis of JNA. Surgical treatment was recommended but refused by religious reasons. We initially treated the patient with external-beam radiation therapy (total treatments, 12; total dose, 2400 cGy), which, after 7 months, failed to reduce the size of the tumor or relieve the patient's symptoms. We subsequently treated the patient with Cyberknife therapy (total treatments, 3; total dose, 4512 cGy) and observed almost complete disappearance of the tumor after 7 months. After 2 years of observation, there has been no tumor recurrence. Cyberknife therapy is compared with other therapeutic options for JNA, and its benefits are discussed in the context of the findings in the literature.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
6/15. Recurrent angiofibroma invading the skull base--case report.A 16-year-old male presented with a massive nasopharyngeal angiofibroma arising in the nasopharynx, nasal cavity, pterygopalatine fossa, and infratemporal fossa, and eroding the pterygoid process of the sphenoid bone. neuroimaging showed the tumor had infiltrated the parasellar region from the middle cranial fossa and reached the cavernous sinus. The tumor was almost completely removed macroscopically by a modified transbasal approach.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
7/15. A rare complication of embolization in juvenile nasopharyngeal angiofibroma.Juvenile nasopharyngeal angiofibroma (JNA) is one of the most common benign nasal cavity tumors of adolescence. It exhibits a strong tendency to bleed and despite being microscopically benign, its behavior is locally aggressive. Preoperative embolization is helpful to minimize intraoperative bleeding. However, embolization procedure may have some important thromboembolic complications such as central retinal artery occlusion. In this article, a young male with juvenile nasopharyngeal angiofibroma, who lost his vision in the left eye following embolization was presented and the possible therapeutic options in such a complication were discussed.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
8/15. Solitary fibrous tumor arising in the sphenoethmoidal recess: a case report and review of the literature.Recently, solitary fibrous tumors (SFTs) have been reported in the head and neck area, such as the nasal cavity, thyroid, salivary gland, etc. We present a rare case of SFT which arose from the sphenoethmoidal recess of the nasal cavity, penetrating into the sphenoid sinus, and which showed different intensities on magnetic resonance imaging (MRI) according to the occupied locations. T2 weighted magnetic resonance (MR) images showed low intensity in the nasal cavity, and iso-intensity in the sphenoid sinus. Enhancement with gadolinium contrast on T1-weighted images was more remarkable in the sphenoid sinus than in the nasal cavity. While the tumor in the nasal cavity showed abundant collagen and high cellularity in microscopic examination, numerous small vessels and dilated vascular spaces were remarkable in the tumor of the sphenoid sinus. MRI findings corresponded to pathological findings. We review SFTs in the head and neck area in the English literature.- - - - - - - - - - ranking = 0.23912358892846keywords = cavity (Clic here for more details about this article) |
9/15. Juvenile nasopharyngeal angiofibroma.Juvenile nasopharyngeal angiofibroma is a rare, histologically benign yet locally aggressive, vascular tumor that typically affects adolescent males. It accounts for 0.5 percent of all neoplasms of the head and neck. A case of juvenile nasopharyngeal angiofibroma manifesting in the oral cavity in a 20-year-old male patient is presented and discussed.- - - - - - - - - - ranking = 0.2keywords = oral cavity, cavity (Clic here for more details about this article) |
10/15. Transnasal endoscopic surgery in juvenile nasopharyngeal angiofibroma.A case of angiofibroma limited to the right posterior nasal cavity, nasopharynx and pterygopalatine fossa was operated upon transnasally under endoscopic control. The tumour was completely excised without complications. Endoscopic follow-up for the next two years and contrast computed tomography (CT) excluded any residual tumour or recurrence. The advantages, limitations and possible complications of this approach are discussed. It seems that in limited lesions of angiofibroma, the option of a transnasal endoscopic approach could be cautiously considered by experienced surgeons.- - - - - - - - - - ranking = 0.047824717785693keywords = cavity (Clic here for more details about this article) |
