title: A clinical observation to diagnose parotid hemangioma.
abstract: A clinical observation to diagnose parotid hemangioma is presented in this article. A hemangioma can be made to distend by blocking its venous outflow. If a distended hemangioma is located within the parotid gland, it stretches the parotid capsule. Thus application of pressure over parotid venous outflow causes the hemangioma to bulge, thereby stretching the parotid capsule. It makes the outline of the gland clinically apparent. This observation is useful to differentiate a hemangioma present in the parotid gland from one that is placed outside the gland like an intramuscular hemangioma of the masseter muscle or internal jugular phlebectasia.
