11- vincent's angina



Vincent's Angina of the Left Tonsil. The ulcer is friable and bleeds easily when swabbed.

Vincent's Angina ia an acute necrotizing infection of the pharynx caused by a combination of fusiform bacilli (Fusiformis fusiformis - a Gram -ve bacillus) and spirochetes (Borrelia vincentii ). These are the same organisms that cause a gingivostomatitis known as trench mouth.

The patient complains of unilateral sore throat that increases in intensity over several days with an associated referred earache on the same side. In addition, the patient complains of a bad taste in the mouth and a fetid bad breath.

On examination, there is a deep well circumscribed unilateral ulcer of one tonsil. The base of the ulcer is gray and bleeds easily when scraped with a swab. There may also be an associated submandibular lymphadenopathy.

Vincent angina is diagnosed using a gentian violet-stained smear of the pharyngeal exudate, which demonstrates the presence of Fusobacterium and spirochetes.

Penicillin or Clindamycin and surgical debridement are the recommended treatment.
