Endoscopic Approach to Oncocytic Schneiderian Papilloma: A Rare Nasopharyngeal Mass Lesion
نویسندگان
چکیده
Schneiderian papillomas are benign neoplasms of the nasal cavity and paranasal sinuses arising from the surface epithelium which are also associated with malignant transformation. These neoplasms have three subtypes, namely fungiform, oncocytic, and inverted. Oncocytic Schneiderian papilloma is the rarest of the three morphological variants. It usually presents with unilateral intranasal polypoid lesions. Nasopharyngeal origin of this mass lesion is extremely rare. Herein, we report a 44-year-old male case of oncocytic Schneiderian papilloma arising from the nasopharynx and discuss the evolution process, clinical findings, and treatment modalities in the light of the literature data.

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 کاملHigh uptake in schneiderian papillomas of the maxillary sinus on positron-emission tomography using fluorodeoxyglucose.
Schneiderian papillomas are benign tumors of the nasal cavity and paranasal sinuses often asymptomatic in their early stages. We report a case of a maxillary sinus oncocytic schneiderian papilloma first detected by positron-emission tomography by using fluorodeoxyglucose (FDG). Schneiderian papillomas demonstrate increased FDG uptake, similar to that of other oncocytic tumors, making it importa...

INTRODUCTION F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) is useful for the staging and assessment of treatment response in patients with lymphoma. Occasionally, benign lesions demonstrate avid FDG uptake and result in false positive findings. CASE We report the case of an 82-year-old man presenting with cutaneous lesions, which were histopathologicall...
متن کاملUndifferentiated carcinoma in oncocytic Schneiderian papilloma. A rarity.
The term Schneiderian mucosa refers to the ectodermally derived lining of the nasal cavity and paranasal sinuses, composed generally of stratified ciliated columnar cells, loose abundant lamina propria, and minor salivary glands and their ducts. This unique mucosa may give rise to three distinct histomorphologic papillomas collectively called Schneiderian papillomas. Hyams has described these v...
