Nasal gliomas are rare, benign, congenital tumors that are throught to be the result of abnormality in embryonic development. Three types of clinical presentations have been recognized; extranasal, intranasal and combined. Clinically, these masses are non-pulsatile, gray or purple lesions that obstruct the nasal cavity and can lead to various complications. Histologically, they consist of astro...

Paragangliomata of the head and neck, although a recognised entity, are extremely rare tumours and will be encountered by only a few clinicians. Furthermore, the nasal cavity and nasopharynx are among the least common sites in which this neoplasm may arise. We describe a case of a paraganglioma of the nasal cavity mucosa and draw attention to the difficulties encountered in predicting the biolo...

Schwannomas are neurogenic tumors arising from the Schwann cells present in neural sheath of myelinated nerves. These benign that can arise anywhere body. rarely seen nose and paranasal sinuses representing <4% all head-and-neck schwannomas. Surgical excision is treatment choice these cases. Nasal polyps common nasal cavity lesions which usually inflammatory polyps. Schwannoma presented with...

Nasal chondromesenchymal hamartoma (NCMH) is a rare nasal benign tumor, which arises from the nasal cavity or paranasal sinuses. In this article, we present a five-year-old male patient with rhabdomyosarcoma unity in remission that emerged with nasal obstruction. Synchronous diagnosis of pediatric tumors such as pleuropulmonary blastoma in the literature is a remarkable finding. We found a mass...

Amelonotic malignant melanoma; Sinonasal cavity; Nasal polyposis; Immunocytochemistry Abstract Malignant melanoma involving mucosal surface of the head and neck region is rare. Malignant melanoma involving the nasal cavity is even rarer and accounts for less than 1% of cases. Prognosis is generally poor with unpredictable outcome. Regional and distant metastasis is common at presentation. We pr...

Esthesioneuroblastoma (ENB) is a neuroendocrine tumor that typically manifests as advanced stage malignancy in the superior nasal cavity. The hallmark symptoms include nasal obstruction and epistaxis, which result from local tissue invasion. Atypical clinical features can also arise and must be considered when diagnosing and treating ENB. These can include origin in an ectopic location, unusual...

A 30 year old man was referred to this department with an intractable obstruction in one nasal cavity and catarrh of indeterminate duration. Inspection of his nose showed that one nasal cavity was normal; the other, however, was filled by a large polyp and mucopus. An x ray film of the paranasal sinuses showed a metallic radio-opaque area in the nasal cavity resembling a bullet (figure). The ma...

INTRODUCTION Malignant melanoma rarely develops in the mucous membranes. Statistical data indicate that rhinosinusal mucosal melanoma was reported in less than 1% of all melanic tumors and in 2-8% of all cancers developed in the nasal fossae and sinuses. Due to reduce and non-specific symptoms and a high degree of invasion away, patients come for a medical expertise in advanced stages of the di...
