ABSTRACT
Malignant lymphoma of the parotid gland not infrequently presents as a solitary mass indistinguishable from other commonly occurring lesions. Two new cases are presented here with a comprehensive literature review. When encountered, the lesion should be excised with the superficial lobe of the gland. If it is within the deep lobe, the tumor should also be excised with preservation of the facial nerve. Recommendations for further evaluation and treatment are given.

Experiments in the excised dog heart and in live dogs are presented wherein a method of induced right ventricular wall resonance has been utlized to estimate the pressure in the right ventricle of the heart. Externally induced cardiac wall vibrations produced low frequency signals which, when subjected to spectrum analysis and coherent signal processing, permitted close approximation of static pressures and wave forms in the right ventricle at normal and hypertensive levels.
