Rhabdomyosarcoma of the Paranasal Sinuses Initially Diagnosed as Acute Sinusitis

Rhabdomyosarcoma of the Paranasal Sinuses Initially Diagnosed as Acute Sinusitis

Rhabdomyosarcoma (RMS) is an uncommon soft tissue malignancy that is typically found in the pediatric population. Here we describe a rare case of widely metastatic alveolar RMS of the right paranasal sinuses in an adult woman who presented with several months of unilateral sinus symptoms that was initially misdiagnosed as acute sinusitis. A middle-aged female presented with two months of right ...

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...

Posttransplantation lymphoproliferative disorder of the paranasal sinuses mimicking invasive fungal sinusitis: case report.

Posttransplantation lymphoproliferative disorder (PTLD) is a challenging complication associated with organ transplantation and is usually fatal if untreated. We describe the case of a transplant recipient who presented with rapidly progressive cranial nerve palsies due to PTLD that originated in the sphenoid sinus. In this case, the clinical and radiologic presentation of PTLD mimicked invasiv...
