Adenocarcinomas of various types comprise 10 to 20% of all primary malignant neoplasms of the nasal cavity and paranasal sinuses. They are thought to originate from seromucous glands of the nasal cavity and paranasal sinuses as well as the surface epithelium. Long-term prognosis is poor and patients usually die due to local spread with no metastasis. This clinical report describes a method for ...

Serious infection in the paranasal sinuses may present with symptoms suggestive of neurological disease and thus lead to delay in the diagnosis and subsequent treatment. We present three such cases inwhom the initial diagnoses had been acute optic neuritis, a posterior communicating aneurysm and an intracranial space occupying lesion. The fourth patient had meningitis but the paranasal sinuses ...

Lymphoma is usually the malignant tumor which originates from lymph node or lymph-tissues. The nasal cavity and paranasal sinuses are rare primary sites for lymphoma. In the paranasal sinuses, lymphoma of maxillary sinuses is the most common, ethmoidal sinuses is more than that of frontal sinuses, sphenoid sinuses is the least. The most common presenting symptoms are nasal obstruction, rhinorrh...

The orbit is involved in 10% of all lymphomas. Paranasal sinuses and nose are other sites for extranodal lymphoma that are involved in upto 2.6 to 6.7% of lymphomas involving head and neck region and are second most common presentation of extranodal lymphoma. In nearly 22.5% of patients, sinonasal lymphoma and orbital lymphoma may coexist. The present report describes such patient with first pr...

Inverted papilloma is an interesting benign tumour arising from lining epithelium of paranasal sinuses which most commonly involves nasal cavity and sinuses. Extension to orbit a rare presentation. It uncommon intermediate grade epithelial the cavity, with tendency recur associated malignancy, Schneiderian membrane Reporting case inverted right well differentiated squamous cell carcinoma, invad...

Chordomas are malignant, nonepithelial neoplasms derived from notochordal tissue. A primary chordoma of the nasal cavities and paranasal sinuses is extremely rare compared with clival chordomas, which often present as nasal masses after spreading anteriorly. Only a few cases of primary chordoma of the nasal cavities and paranasal sinuses have been reported in the literature. We report a case of...
