Carcinoma of the Paranasal Sinuses

Disorders of the Paranasal Sinuses

Inflammation of the equine paranasal sinuses is a relatively uncommon disease that may be caused by primary bacterial or mycotic infections (Mason 1975a), or can be secondary to dental disease (van der Velden & Verzijlenberg 1984, Scott 1987, Tremaine & Dixon 2001a), facial trauma, sinus cysts, progressive ethmoid hematoma or sinonasal neoplasia (Mansmann & Wheat 1973, Gibbs & Lane 1987, Tremai...

Mucoceles of the paranasal sinuses.

Actinomycosis of the paranasal sinuses.

Actinomycosis is a chronic suppurating granulomatous disorder specific to soft tissue. It is produced by Actinomyces Israelii, gram positive anaerobic bacteria that are very difficult to culture, and a commensal saprophyte of the oral cavity (tonsillar crypts, saliva and gingival dental sulci) and the gastro-intestinal tract; it becomes a pathogen in the face of erosions of the oropharyngeal mu...

Primary Small Cell Neuroendocrine Carcinoma of Paranasal Sinuses

Small cell neuroendocrine carcinoma of the paranasal sinuses is an extremely rare and aggressive neoplasm. Despite aggressive management, the tumor carries a poor prognosis, with a high risk of local recurrence or distant metastases. The management strategy is based on that for pulmonary small cell cancer and includes platinum-based chemotherapy combined with radiotherapy. We are reporting a ca...

[Aspergillosis of the nose and paranasal sinuses].

Aspergillosis is becoming an increasingly recognized pathogen in the sinonasal tract. The courses of two patients, one seemingly healthy and one with a terminal malignancy, are reviewed. These patients illustrate the clinical course, difficulties in diagnosis, and management of patients with aspergillosis of the sinonasal tract. Aspergillus is a common endogenous contaminant of the upper respir...
