1/62. Pleomorphic adenoma of the nasal septum.Pleomorphic adenoma is the commonest benign tumour of the major salivary glands. It can also occur in minor salivary glands, mainly in the oral cavity, but also in other sites in the head and neck both within and outwith the upper aerodigestive tract. We present a rare case of pleomorphic adenoma of the nasal septum with consideration of the clinical management and a review of the literature.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/62. Malignant oncocytoma of the nasal cavity: a case report.Malignant oncocytoma is a rare clinical entity and is most commonly seen in the salivary glands. Its occurrence in the nasal cavity is extremely rare, and only 4 such cases have been reported in the literature. The authors report one such case in a 60-year-old woman, which presented as a slow-growing nasal mass arising from the nasal septum, with no lymph node metastasis, which was successfully managed by a combined modality of treatment-surgery followed by radiation therapy. The relevant literature has been reviewed. The case is discussed as a possible differential diagnosis for a mass in the nose.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
3/62. Blastomatous tumor with teratoid features of nasal cavity: report of a case and review of the literature.A case of blastomatous tumor with teratoid features is presented. The polypoid mass was observed in the left nasal cavity of a 72-year-old man. Histologically, the lesion was composed of neuroepithelial cells with blastomatous appearance, cystic squamous nests filled with keratin materials, many mucous glands, complex tubular and glandular structures with edematous fibroblastic stroma. Sinonasal neoplasms including teratoid components and immature neuroepithelium are exceedingly rare. We suggest that the term 'immature teratoma' is more suitable than blastoma or blastomatous tumor when there is no carcinomatous or sarcomatous component besides the immature neuroepithelium and teratoid elements.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
4/62. Common head and neck manifestations of AIDS.head and neck manifestations of acquired immunodeficiency syndrome (AIDS) can involve the skin, ear, upper aerodigestive tract, and neck. Several head and neck manifestations of AIDS may be the only initial sign of this disease process and therefore primary-care physicians and otolaryngologists must be able to recognize and understand the management of these lesions. Cystic enlargement of the parotid gland and Kaposi's sarcoma are increasingly being encountered in the head and neck exam of hiv-infected patients. An example of each of these disease processes is presented with full discussion about the various treatment methods.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
5/62. A case report of FSH-producing nasal ectopic pituitary adenoma extending to the frontal cranial fossa.We report the first case of an ectopic pituitary adenoma in the nasal cavity that produced follicle-stimulating hormone (FSH). A 60-year-old man complaining of left nasal bleeding had a polypoid tumor in the left nasal cavity. Findings of computed tomographic scanning and magnetic resonance imaging showed that the tumor originated from the olfactory cleft, occupied the nasal cavity, and extended to the frontal cranial fossa. Results of histologic examination suggested ectopic pituitary adenoma. magnetic resonance imaging results showed the pituitary gland to be normal. Electron microscopy findings demonstrated a large number of secretory granules in the tumor cells that were positive for FSH on immunohistochemical analyses. serum gonadotropin levels were normal, and no clinical signs of hypersecretory syndrome were noted. The above findings led us to establish the diagnosis of FSH-producing ectopic pituitary adenoma. The patient underwent craniofacial resection of the tumor followed by an uneventful recovery. The pathologic findings and clinical course of the case were comparable to those of FSH-producing adenomas arising from the pituitary gland.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/62. Acinic cell carcinoma originating in the nasal septum.Acinic cell carcinoma represents approximately 2.5% to 4% of all salivary gland tumors and 13% of all malignant parotid tumors. The nasal septum is a rare site of an acinic cell carcinoma. We have treated such a tumor in a 47-year old man who had been asymptomatic for the past 1.5 year. This is the second reported case of acinic cell carcinoma at the nasal septum.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
7/62. Olfactory neuroblastoma metastatic to the breast.Olfactory neuroblastoma (Esthesioneuroblastoma) is a rare malignant tumour arising from olfactory epithelium. It has a predilection for cervical lymph node metastasis and also has potential for distant metastasis to unusual sites like scalp, face, aorta, spleen, liver, adrenal gland and ovary. We report here a rare case of olfactory neuroblastoma in an adolescent girl with metastatic deposits in the breast. A poor prognosis due to rapidly progressive disseminated disease was observed. The relevant literature regarding metastatic olfactory neuroblastoma and metastasis in the breast from non-mammary malignant neoplasms is reviewed.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
8/62. Teratocarcinosarcoma of the nasal cavity. Report of a case showing favorable prognosis.We report a very rare case of teratocarcinosarcoma of the nasal cavity showing a favorable prognosis. The patient was a 66-year-old man with a mass completely obstructing the right nasal cavity. Subsequently, extirpation of the mass and Denker-Watsuji operation were performed, and the patient was treated with a combination of radiation therapy and chemotherapy. Neither recurrence nor distant metastasis was observed during follow-up lasting 30 months. Histologic examination of the resected mass revealed several tissue elements including columnar and squamous epithelia with atypia, smooth muscle cells with rare mitotic activity, and neuroectodermal tissue. The glandular epithelium and smooth muscle cells were reminiscent of a primitive intestinal organoid structure, suggestive of teratomatous tumorigenesis. Our case and a review of the literature indicate that the absence of invasiveness to the stroma or surrounding tissue is closely related to a favorable prognosis.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
9/62. Case report: Sinonasal teratocarcinosarcoma.Sinonasal teratocarcinosarcoma (SNTCS) is a rare, teratoma-like lesion of the nasal cavity and paranasal sinus. To the best of our knowledge, SNTCS is highly malignant. We report a case of SNTCS arising in the nasal cavity of a 71-year-old male who complained of nasal obstruction and epistaxis. In spite of intensive treatment, the tumor recurred three times and the patient died from a local extension into the anterior cranial fossa 7 years after initial onset. The resected tumors consisted of variegated components, such as epithelial elements, including cystic, ductal and glandular structures occasionally associated with squamous differentiation, neuroectodermal ones exhibiting neural rosette formation, and mesenchymal ones with prominent rhabdomyoblastic differentiation. Immunohistochemical and ultrastructural studies clearly demonstrated characteristic cellular differentiation of each component. These three principal elements were often topographically related and showed morphological transition with each other. These findings suggest the derivation of divergent components from common progenitor cells. Although the cellular atypia of the primary lesion was inconspicuous, the recurrent tumors became anaplastic and mitotically active. Histologic anaplasia may be somewhat related with aggressiveness of recurrent lesions. Appropriate sampling of specimens, and awareness of this rare teratoid tumor are important to make the correct diagnosis.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
10/62. Post-nasal space oncocytoma: a different approach to a rare tumour.Oncocytomas are rare tumours that occur predominantly in the major salivary glands, particularly the parotid of older individuals. We present the exceptionally rare occurrence of an oncocytoma in the post-nasal space and its treatment for the first time via a Le Fort I osteotomy. The potential for local spread to the surrounding skull base makes it vital to achieve good oncological clearance. We found that this was possible using the Le Fort I technique and would recommend that this approach should be considered in future, when approaching such lesions.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
