Is a  lump behind the right nostril a cyst requiring a CT scan?
Patient: 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 I've 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? Doctor: Hello,I have gone through your query and I can understand your concerns.Probable diagnosis: Sebaceous cyst.Differential dagnosis: cutaneous lipoma/dermoid cyst/boilstreatment:surgical excisionAll the symptoms and signs you have mentioned suggest the possibility of a sebaceous cyst.Some other condition like dermoid,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.Dr.Shinas Hussain
