1/10. 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 = neoplasm (Clic here for more details about this article) |
2/10. Meningiomas of the paranasal sinuses.Extracranial meningiomas are rare tumors, comprising approximately 2% of all meningiomas. Previously reported sites include the orbit, parapharyngeal space, and rarely, the paranasal sinuses. A retrospective chart review of patients with meningiomas was performed over the last 25 years, and three patients were identified with meningiomas involving the paranasal sinuses. The locations included the frontal sinus, the ethmoid sinus, and the sphenoid sinus. Presenting symptoms included facial pain and nasal obstruction; two patients noted facial swelling. diagnosis was established via endoscopic transnasal biopsy in two patients. Computed tomographic (CT) guided biopsy was utilized to confirm the diagnosis in the third patient. Surgical extirpation was successfully performed with tumors arising from the ethmoid and frontal sinuses. The patient with neoplasm in the sphenoid sinus underwent radiation therapy. Extracranial meningiomas of the paranasal sinuses are rare tumors that may present a diagnostic and therapeutic challenge. We present three cases and discuss the clinical presentation, radiographic findings, diagnostic evaluation, and treatment options.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/10. Management pitfalls in the use of embolization for the treatment of severe epistaxis.Angiographic embolization for the treatment of severe recurrent epistaxis was added to the traditional treatment options--nasal packing, cauterization, and surgical vessel ligation--in 1974. Since then, clinical experience has shown that this procedure is safe and effective. When epistaxis cannot be controlled with cautery, nasal packing is the most common next step. As such, it is often performed by emergency physicians and other clinicians who are not otolaryngologists. We report two cases in which intranasal neoplasms were obscured as a result of a significant distortion of the normal anatomy. This distortion was secondary to emergency-room treatment of severe epistaxis by repeated nasal packing followed by angiographic embolization. Pre-embolization angiographic studies and subsequent postembolization endoscopic evaluations did not reveal the presence of the occult neoplasms because of the presence of inflammation and edema after treatment. Clinicians should be aware that nasal packing and embolization can obscure the underlying source of epistaxis, and follow-up radiologic studies and endoscopic evaluations are essential to avoid delays in diagnosis.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
4/10. Giant intracavernous internal carotid artery aneurysm with fatal epistaxis.The case history and autopsy findings of a 32-year-old male, who suffered a mild closed-head injury and then had repeated epistaxis beginning 5 months later, is presented. The condition culminated in an episode of fatal epistaxis 1 year after the injury. At one time during the course of his work-up, the etiology of his repeated epistaxis was thought to be a vascular nasopharyngeal neoplasm. The diagnosis of an intracavernous internal carotid artery aneurysm was made only at autopsy. The principles of management of traumatic intracavernous internal carotid artery aneurysm presenting with epistaxis are discussed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/10. epistaxis as a rare presenting feature of glomus tympanicum.Glomus tumours are the most common primary neoplasms of the middle ear, typically benign and slowly progressive. Pulsatile tinnitus and ipsilateral hearing loss are the most common symptoms at presentation by far; otalgia, aural fullness and otorrhoea being less frequent. A case of primary glomus tympanicum presenting with recurrent epistaxis, previously unreported in the literature, is described and associated imaging presented.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
6/10. 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 = 1keywords = neoplasm (Clic here for more details about this article) |
7/10. Epithelioid hemangioendothelioma of the nasal cavity.Epithelioid hemangioendothelioma (EH) is an unusual vascular neoplasm characterized by proliferation of endothelial cells with epithelioid morphology. It has an indolent course, with the potential for recurrence, but rarely metastasizes. The common locations include soft tissue, skin, viscera and bone. We present an unusual case of EH in the nasal cavity and describe the clinical characteristics, histopathologic findings, differential diagnosis and management. The 25-year-old male patient initially presented with an 8-month history of intermittent epistaxis. Nasal endoscopy revealed a vascular tumor involving the nasal cavity. The tumor was excised and the final histopathologic diagnosis was consistent with EH. EH in the head and neck is extremely rare. Wide excision is the treatment of choice, and regular follow-up is suggested due to the potential for recurrence. Definitive diagnosis depends on histopathologic and immunohistochemical features.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/10. MRI of intranasal pleomorphic adenoma.A pleomorphic adenoma in the nasal cavity constitutes a rarity. A 48-year-old woman presented with intranasal pleomorphic adenoma revealed by unilateral continuous obstruction and occasional epistaxis. Nasal endoscopy showed a mucosa-covered and opalescent polypoidal mass arising from the left nasal septum. Unlike cases affecting the major salivary gland, magnetic resonance image (MRI) revealed that the mass showed a low signal intensity on T1-weighted image and a heterogeneous, intermediate signal intensity on T2-weighted image. MRI findings can aid in diagnosis and help exclude the possibility of other neoplasms that occur at this site.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/10. Nasal schwannoma.A 36-year-old man with a nasal septal mass is presented. The diagnosis of a benign neoplasm arising from peripheral nerve schwann cells was made by excisional biopsy. A benign nerve sheath tumor may be either a schwannoma or neurofibroma. Schwannomas may be distinguished from neurofibroma by clinical and histologic criteria. Malignant degeneration and intracranial extension may complicate the course of a nasal schwannoma. Complete excision is the preferred therapy.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/10. craniopharyngioma arising in the pharyngeal hypophysis.Four cases of nasopharyngeal craniopharyngiomas have been previously reported in the medical literature. They were, in fact, only nasopharyngeal extensions of tumors originating in the anterior pituitary of the sella turcica. Pituitary adenomas can arise from any part of the craniopharyngeal canal. Supporting this theory are four reported cases of pituitary adenomas in the body of the sphenoid bone separate from both the sella turcica and the nasopharynx. The discovery by Erdheim in 1904 of the pharyngeal hypophysis located on the posterior edge of the vomerine bone raises the possibility of a tumor arising in this tissue. We report the case of a craniopharyngioma limited entirely to the nasopharynx and specifically to the posterior end of the vomer. We believe it to be the only reported example of a true neoplasm of the pharyngeal hypophysis first described by Erdheim.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
