Simultaneous Nasal Septal Schneiderian Papilloma and Respiratory Epithelial Adenomatoid Hamartoma.

Schneiderian papilloma is typically found on the lateral nasal wall, but, in rare cases, can be located at the mucosa of the nasal septum. Respiratory epithelial adenomatoid hamartoma (REAH) is rare, non-neoplastic lesion characterized by an abnormal proliferation of glandular part of the respiratory nasal mucosa. We present a case of a 42-year-old man with five-year history of bilateral nasal obstruction, rhinorrhea, epistaxis, and hyposmia.

Different levels of mucus inflammatory mediators in nasal polyposis with and without aeroallergen sensitivity.

Objectives: Biomarker levels in nasal secretions can reflect the inflammatory status of nasal mucosa and evolution of sinus disease. The aim of this study was to evaluate the relationship between local inflammatory mediator production and clinical characteristics of patients with nasal polyposis (NP).

Methods: Thirty-one nonaeroallergen sensitized patients with NP (NANP), 29 aeroallergen sensitized patients with NP (ANP), and 30 subjects without inflammation of nasal mucosa as controls (C) entered this prospective, cross-sectional study.

Maxillary Sinus Lobular Capillary Hemangioma in a 15-Year-Old Boy.

Lobular capillary hemangioma (LCH) is a benign capillary proliferation with a microscopically distinctive lobular architecture, composed of small to medium-sized vessels of capillary type. Rarely, it originates from the mucosa of the nasal cavity, most frequently from the anterior nasal septum, turbinates, and nasal vestibule. Etiology is unclear, but previous investigations suggest that this lesion is associated with injury, hormonal factors, some viral infections, and therapy with some drugs.

Choanal polyps in children and adults: 10-year experience from a tertiary care hospital.

Purpose: Choanal polyps (CPs) are benign, solitary, soft-tissue lesions extending towards the junction between the nasal cavity and the nasopharynx through the choana. The aim of this retrospective study was to evaluate clinical and histological characteristics of CPs in children comparing to adult patients.

Methods: Characteristics of CPs treated in our hospital (demography, main complaints, side, localization, surgical approach, histological characteristics, accompanying paranasal sinus diseases, association with allergic rhinitis, postoperative follow-up period, and recurrence rates) were retrospectively reviewed.
