<s>[INST] Hi my name is Dani and on behalf of my sister I wanted to ask a question about a health issue. She has a strange lump in the inside of her jaw, but you cant see it form the inside of her mouth. We think that it may be a Glandular Odontogenic Cyst, but we arent sure. Shes had for a long time, about ten or more years. We didnt know what it was and she never told my parents until recently she woke up and it was swollen. Its been swollen for several days, but she is in no pain until pressure is applied to the area where the lump is. Is there any way we could find out? We wont be able to go to the doctor until she gets back on my dads health insurance plan. Thanks for reading and thanks for your help. [/INST] Hello, first I would like to know how come u have diagnosed the lesion- as glandular photogenic cyst. Was biopsy taken. Without biopsy nothing can be confirmed about any of painless swelling in the jaw.  If it is being diagnosed earlier then. The treatment plan will be surgical nucleation of the cyst along with RCT in involved teeth if required.as cyst sometimes in long course damages periapical area of teeth also. Do not postpone treatment now as already 10 yrs have been delayed and the size of lesion has been increased. More swelling indicates increased loss of bone or tissues in the region. Any cystic lesion should be surgically removed as soon as possible on diagnosis as they after long term may have potential to turn to any malignant lesion too.  And regarding any kind of painless long-standing swelling of jaws diagnostic protocols are-clinical examination, FNAC, radiograph of region OPG, PA,Lat Oblique, causal, if closed to vital regions then CT Scan for knowing exact involvement of hard tissues, if soft tissue cyst is there then sonography and MRI of region along with incisional biopsy in both cases... later than per diagnosis after pathological assessment and clinical evaluation the treatment plan will be decided...take care. </s>
