Hemorrhagic tonsillitis.

Eleven patients with acute and/or chronic tonsillitis, who presented with a spontaneous tonsillar hemorrhage are reported and discussed. Two patterns of hemorrhage were noted: 1. diffuse, parenchymal bleeding and 2. localized bleeding from dilated surface vessels. Pharyngeal culture for group A beta-hemolytic Streptococcus was positive in six patients (55%). Monospot, heterophile antibodies, complete blood cell count, prothombin time, partial thromboplastin time, and viral studies did not consistently demonstrate any abnormality. Two patients, however, did have an elevation in liver enzymes. In five patients, the bleeding stopped spontaneously; in five patients the bleeding was controlled with local chemical cautery. In two patients, Avitene was used for hemostasis. One other patient's bleeding was controlled by electrocautery while the patient was under anesthesia for endoscopic evaluation of hemoptysis. Two patients required blood transfusions; one of these patients had a history of factor IX deficiency. Four case histories are discussed in detail to illustrate the varied clinical presentation and some pitfalls in diagnosing and managing this rarely reported complication of tonsillitis. Possible mechanisms for the pathophysiology include increased tonsillar blood flow, necrosis of tonsillar surface cells, and trauma to dilated surface vessels. No common bacterial or viral etiology could be determined in this rare, but potentially serious, complication of tonsillitis.
