Polymorphous low-grade adenocarcinoma is a rare malignancy arising from the minor salivary glands in the aerodigestive system, most frequently the hard palate. The treatment of choice is wide surgical resection, and the efficacy of radiotherapy has not been confirmed. A 54-year-old male presenting with a mass at the base of the tongue performed transoral laser microsurgery. The pathologic diagn...

The purpose of present study is to discuss the clinical findings and management options of posterior polymorphous corneal dystrophy and to review the current literature on this rare entity. We report a case of asymptomatic posterior polymorphous corneal dystrophy. Posterior polymorphous corneal dystrophy is a rare, familial clinical entity with subtle findings that are important to recognize, a...

BACKGROUND During a 2.9-year period, 11 patients developed polymorphous ventricular tachycardia 1-13 days after acute anterior (seven patients) or inferior (four patients) myocardial infarction. None of the 11 patients had sinus bradycardia (mean heart rate, 90 +/- 23 beats/min), but three had a sinus pause immediately before the onset of polymorphous ventricular tachycardia. In all 11 patients...

Posterior polymorphous dystrophy is a rare corneal dystrophy, usually detected by chance. This case series describes the morphologic features in the three different types of posterior polymorphous dystrophy using confocal microscopy.

Polymorphous computing architectures are being developed to provide high performance across a wide range of DoD applications. In this paper, we describe a multiprocessor PCA prototype system and provide measured application and communication performance results for a polymorphous architecture.
