1/34. Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/34. Lobular capillary haemangioma of the nasal cavity: observation of three specific cases.Lobular Capillary Haemangioma of the nasal cavity: observation of three specific cases. Lobular Capillary Haemangioma, unproperly called "Pyogenic granuloma", is a benign vascular tumour pedunculated on the skin and on mucous membranes of the oral and nasal cavities. Microtrauma and pregnancy are the most often evocated aetiologic factors. epistaxis and nasal obstruction are the most marked symptoms of this irregular and friable mass. We report three cases (two adult and one paediatric) of this pathology. Two have as trigger factor a nasal microtrauma, the third an oestro-progestative impregnation. A clinical, radiological and histological description allows us to expose the characteristics of this lesion that remains obscure to many rhinologists. Lobular Capillary Haemangioma has to be evocated in the differential diagnosis of each haemorrhagic endonasal mass.- - - - - - - - - - ranking = 0.83333333333333keywords = cavity (Clic here for more details about this article) |
3/34. Osteocartilaginous differentiation of mucosal melanoma in the sinonasal cavity.We present a very rare case of mucosal melanoma with osteocartilaginous differentiation (MMOD). This is the first report of MMOD originating in the sinonasal cavity. Preoperative diagnosis of this tumor from specimens resected for biopsy alone is very difficult, because it has 2 histopathologic components: a primary melanoma site and the part of the melanoma with osteocartilaginous differentiation. The immunohistochemical technique is useful in histopathologic diagnosis of this tumor. Malignant melanoma usually shows reactivity with MelanA (melanoma tumor antigen) and S-100 proteins. We diagnosed this case as MMOD because both regions in this tumor were stained with MelanA and S-100 proteins. magnetic resonance imaging provides the best clinical ability to detect malignant melanoma in the sinonasal region. In this case, the melanotic melanoma site in the posterior ethmoid sinus appeared hyperintense to gray matter on T1-weighted image magnetic resonance imaging. Thus, it would have been possible to diagnose this case as MMOD before operation, even though we could not obtain a biopsy specimen from the posterior ethmoid sinus lesion.- - - - - - - - - - ranking = 0.83333333333333keywords = cavity (Clic here for more details about this article) |
4/34. A case of internal carotid artery aneurysm diagnosed on basis of massive nosebleed.The authors report a rare case of a nontraumatic giant internal carotid aneurysm which ruptured into the nasal cavity, causing massive rhinorrhagia in a 64-year-old Japanese woman. CT images of the head revealed an aneurysm having a diameter of about 5 cm with a neighboring area of erosion of the anterior base of the skull, and a swelling extending to inside the sphenoidal sinuses. Cerebal angiography resulted in a diagnosis of a giant aneurysm of the left internal carotid artery. Coil embolization and other surgical treatments were recommended, but the patient's family refused to consent and requested only conservative therapy. The natural course of the patient was thus followed, and the patient died after repeated episodes of aneurysm rupture and massive nosebleeds. It was concluded that curative therapy should be administered as soon possible upon diagnosis of this disease.- - - - - - - - - - ranking = 0.16666666666667keywords = cavity (Clic here for more details about this article) |
5/34. paraganglioma of the nasal cavity: a case report.We describe the case of a 72-year-old woman presenting with a 1-year history of recurrent epistaxis and unilateral progressive nasal obstruction with associated rhinolalia resulting from the presence of a tumor mass occupying two-thirds of the right nasal cavity. Histopathologically, neoplastic cells or "chief cells" were arranged in well-defined nests, which had the classic alveolar or so-called "zellballen" pattern. Immunohistochemical studies highlighted the presence of S-100 protein-positive sustentacular cells located at the periphery of the clusters of chief cells. The chief cells showed a diffuse and intense positivity for neuron-specific enolase and synaptophysin. A diagnosis of paraganglioma was made. The lesion was excised completely and the patient did not develop recurrences or distant metastases after 8 months of follow-up. Paragangliomas arising in the nasal cavity and paranasal sinuses are extremely rare tumors. We report on the clinical, histopathological and immunohistochemical findings of our case and review the cases previously described in the literature.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
6/34. Inflammatory myofibroblastic tumour of paranasal sinuses with fatal outcome: reactive lesion or tumour?Inflammatory myofibroblastic tumours (IMTs) are clinicopathologically distinctive but biologically controversial entities, which have been described in the lungs, abdomen, retroperitoneum, and extremities, but rarely affect the head and neck region. IMT usually follows a benign clinical course after radical excision, but invasive, locally recurrent, and metastatic forms of abdominal and mediastinal IMT have also been described. This report describes a case of IMT of the paranasal sinuses with a fatal outcome. A 22 year old woman was admitted to hospital as a result of epistaxis. Computed tomography scan and magnetic resonance imaging showed an expansive process in the paranasal sinuses, extending into the nasal cavity, orbita, and endocranium. The tumour progressed despite several surgical procedures. radiotherapy, corticosteroids, and chemotherapy were unsuccessful, and the patient died four years after diagnosis, as a result of extensive intracranial spread of the tumour. This is the first known case of an IMT of the head and neck region with a fatal outcome. It shows that the aggressive behaviour of IMTs is not limited to abdominal and mediastinal locations, and supports recent observations that at least a subset of IMTs represents true neoplasia rather than reactive myofibroblastic proliferation.- - - - - - - - - - ranking = 0.16666666666667keywords = cavity (Clic here for more details about this article) |
7/34. Organized hematoma of the maxillary sinus.OBJECTIVE: Organized hematoma of the maxillary sinus can develop by means of organization of hematoma in the unaerated maxillary sinus. To our knowledge, this is only the second article describing organized hematoma in the maxillary sinus. MATERIAL AND methods: We have observed eight cases of organized hematoma of the maxillary sinus recently and here we describe the clinical features (using CT scans and medical records), radiologic characteristics and pathologic findings. RESULTS: The patients comprised five males and three females (mean age 58 years), all of whom had a history of frequent epistaxis. They also complained of nasal obstruction, hyposmia, headache and swollen cheeks. Rhinoscopy revealed obliterated nasal cavities due to bulging lateral walls. CT scans showed soft-tissue densities expanding the maxillary sinus into the nasal cavity. The treatment modalities used (applied either alone or in combination) were Denker's operation, Caldwell-Luc's operation and endonasal endoscopic surgery, and the outcomes were successful. CONCLUSION: Organized hematoma should be included in the differential diagnosis when patients have frequent epistaxis and an expansile mass in the maxillary sinus.- - - - - - - - - - ranking = 0.16666666666667keywords = cavity (Clic here for more details about this article) |
8/34. Pediatric lobular capillary hemangioma of the nasal cavity.Lobular capillary hemangioma (LCH), also called pyogenic granuloma, is a benign vascular tumor that is pedunculated on the skin and the mucous membranes of the oral cavity. This disease occurs in all ages, but more often in the 3rd decade, and is seen in females more than males. LCH commonly appears in early childhood and affects males more than females in the pediatric age group. The gingiva, lips, tongue and buccal mucosa are the most common sites of mucosal LCH, but the nasal cavity is rare. Micro-trauma and hormonal factors are the most common etiologic factors. epistaxis and nasal obstruction are the most marked symptoms. We describe the case of a 6-year-old girl with intra-nasal lobular capillary hemangioma presented with epistaxis and nasal obstruction. This should be considered in the differential diagnosis of childhood endonasal masses with bleeding. Total excision using endoscopic technique is the treatment of choice.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/34. Accessory meningeal arterial supply to the posterior nasal cavity: another reason for failed endovascular treatment of epistaxis.A patient with intractable posterior epistaxis was treated with embolization of the ipsilateral sphenopalatine and facial arteries and contralateral sphenopalatine artery. She continued to bleed despite a seemingly adequate embolization procedure. A second angiogram revealed a significant collateral blood supply to the posterior nasal cavity from the accessory meningeal artery not identified during the first procedure. This was then embolized with no further epistaxis encountered. This case demonstrates yet another collateral arterial pathway that might account for a failed embolization.- - - - - - - - - - ranking = 0.83333333333333keywords = cavity (Clic here for more details about this article) |
10/34. Infrasellar craniopharyngioma presenting as epistaxis, excised via Denker's medial maxillectomy approach.Infrasellar craniopharyngioma is an uncommon neoplasm. Rarely, it presents with epistaxis. To date, 39 cases of infrasellar craniopharyngioma have been reported in the world literature. Involvement of the maxillary sinus has only been reported once. We report a second case exclusively involving the nasal cavity, ethmoid sinus and maxillary sinus. Excision was performed using a Denker's medial maxillectomy approach.- - - - - - - - - - ranking = 0.16666666666667keywords = cavity (Clic here for more details about this article) |
