Maxillary sinus nonodontogenic myxoma extending into the sphenoid sinus and pterygopalatine fossa: case report.

Myxomas are benign mesenchymal tumors of uncertain etiology. They can arise from odontogenic tissue, as well as from the sinonasal tract and from the facial and temporal bones, apparently from nonodontogenic mesenchyme. Although histologically benign, myxomas are locally invasive.

Evaluation of laryngeal findings in users of inhaled steroids.

The objective of the prospective study is to examine the laryngeal changes by laryngeal videostroboscopy and electromyography (EMG) regarding new-onset dysphonia in asthmatic patients taking inhaled corticosteroids (ICS). Laryngeal changes and electrophysiological status of the laryngeal muscles were evaluated by these methods in 12 patients both at the time of presentation of dysphonia and after cessation of therapy. Laryngeal changes of our patients were mucosal edema, erythema, thickening, adduction deficit, nodule and irregularity in videostroboscopy.

The clinical presentation of toxoplasmosis is mostly asymptomatic and may include subfebrile fever, fatigue, and lymphadenopathy.

Giant trichilemmal cyst at the neck region.

Trichilemmal cyst (TC) is an adnexal skin tumor that usually occurs on the scalp. There is a female dominance in this tumor. Proliferating pilar tumors or cysts arise from this lesion, and the clinical differential diagnosis from TCs must be taken because of aggressive behavior of proliferating pilar tumor.
