perforation of pharyngeal tissue

i got this email from my dentist regarding the hole that the strep bacteria dug into my tonsil. it cracks me up:

When I saw you in November, I told you I had never seem such a prominent perforation of a patient’s pharyngeal tissue following a streptococcal infection. I also said I wanted to research the matter further to see if it really is that unique. I have checked various sources on several occasions and have found no similar description. Not that it matters…it just seemed interesting to me.
