Hello doctor,

I have a yellowish pus sac on my tonsils left side which I noticed a few days ago. A doctor says he thinks it is ectopic, I do not know what that is, but I can submit to you a picture of the spot on my tonsils. I have a good picture of it. I was sick about a month ago with a fever for a day and I had a sore throat.



Welcome to iciniq.com.

I have seen the image (attachment removed to protect patient identity). The yellowish pus sac is a tonsil stone, known as tonsillolith. It occurs due to the accumulation of tonsillar secretions and some minerals inside the tonsillar crypt and obstruction to its free flow into the oral cavity and pharynx. It can occur subsequent to a throat infection or can occur without any reason as well. Does this cause any symptom like soreness or foreign body feeling or itching or painful swallowing? Otherwise, your tonsils and oropharynx area appear fine, without any sign of inflammation or infection. Are you a smoker? Do you have diabetes or hypertension or any illness for which you have to take medicines regularly? The stone sometimes easily comes out when we press it with a tongue depressor or a spatula. We do it in-office after giving a mild anesthetic spray onto the oropharynx and tonsils. Sometimes, however, it does not come off that easily. In some, it produces recurrent symptoms and the stone also forms frequently. They get benefitted by the removal of tonsils altogether. Do write back to us with all the details.

Thank you doctor,

I do not think it is a tonsil stone. If it were, I would press it out myself with a tongue depressor. Please zoom in on the spot, take a good look at the photo and resubmit your answer.

What about symptoms? Do you have a sore throat now? Also, it is either tonsillar stone which has got embedded deep inside or it is a tonsillar cyst (more common in diabetic people). I suggest: 1. Chlorhexidine mouth gargles three times daily for seven days after rinsing your mouth with water. 2. Anti-inflammatory enzymes like Chymotrypsin and Trypsin three times daily for five days. If symptoms do not subside, you will have to start taking antibiotics with some decongestants.
