Oncocytic Schneiderian papilloma.
Oncocytic Schneiderian papilloma, fungiform papilloma, and inverted papilloma are 3 morphologically separate tumors arising from the Schneiderian membrane. Oncocytic Schneiderian papillomas comprise about 3 approximately 5% of this entity. Old-aged group predominates. No sex predilection is noted. Multi-layered eosinophilic epithelium characterizes this kind of tumor. Exophytic and inverted gro...
متن کاملSchneiderian papilloma of the sinonasal tract.
The sinonasal tract, lined by ciliated respiratory mucosa (Schneiderian epithelium), gives rise to three distinct papilloma morphologies. Collectively, these lesions are referred to as Schneiderian papillomas and include inverted (∼50%), exophytic (∼47%), and oncocytic (∼3%) types. The tumors are uncommon, with an incidence of about 2.3 cases per 100,000 population. The lesions develop over a b...
متن کاملSchneiderian Papilloma : A Rare Case Report
The nasal cavity, paranasal sinuses, and nasopharynx are sites for a wide variety of tumors and non neoplastic conditions. Inverted papilloma accounts for about 0.5-4% of total nose and paranasal sinus tumours. Men are affected 4 times more often than women. The major types are fungiform papilloma, inverted papilloma, and oncocytic Schneiderian papilloma. The latter has often been referred to a...
متن کاملInverted papilloma (Schneiderian papilloma) with involvement of the oral cavity: report of an unusual case.
Inverted Schneiderian papilloma (ISP) is a neoplasm of epithelial lining origin which arises in the respiratory mucosa that lines the nasal cavity and paranasal sinuses. The inverted Schneiderian papilloma frequently appears as a unilateral lesion in the nasal septum and extends secondarily to the nasal and paranasal sinuses. This paper reports an unusual case of this pathology with involvement...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
