Patient: Description (onset time, main symptoms, hospital visited, etc.): I had a cold the week before last and took anti-inflammatory medication for a few days, but yesterday I found a sore throat and a lump under my right jaw, which was painful to swallow and press. Today I went for a normal blood test and was diagnosed with a subjugular gland cyst after a puncture and ultrasound. Is there any harm? The cyst is most likely to be a sublingual gland cyst with an “oral shape”, which can be diagnosed by ultrasound, and can be diagnosed by puncture.
