[|Human|] I have a hard lump behind my right nostril for a few months now. At first I thought it was a pimple, but the more i touched it, the bigger it grew. Now that Ive left it alone, it just simply exists and slightly distorts my nose symmetry. 2 dentists have said that it is unrelated to any dental problems. Is this just a cyst or should I get a CT scan?
[|AI|]  Hello, I have gone through your query and I can understand your concerns. Probable diagnosis: Sebaceous cyst. Differential diagnosis: cutaneous lipoma/Desmond cyst/boils treatment:surgical excisional the symptoms and signs you have mentioned suggest the possibility of a sebaceous cyst. Some other condition like Desmond, boils and cutaneous lipoma have to be ruled out before making a diagnosis. There is absolutely no need for a CT scan for this kind of cyst. Definitive treatment is by surgical excision of the cyst. Excised specimen have to be sent for biopsy to confirm the diagnosis. Hope this information help you. Regards. Chat Doctor.
