<s>[INST] my son in 2.5 months old. His left temple seems to have a firm swelling on and around it. It has slowly inncreased in size and now that eye seems to be bulging slightly. We went to the Dr about a month ago for her to look at it and said not to worry about it. he had his 2 month check up recently and everything looked fine, developing ahead of schedule even. We did not discuss the lump/ swelling it was not as prevalent. It seems to be more noticeable at certain times and less noticeable at others. we are going to the dr in 2 days but any ideas would be appreciated, as i am freaking out! [/INST] Hi....If there are no symptoms of raised intracranial tension like incessant vomiting or loss of consciousness or seizures you need not worry about it. By what you quote I feel that it could be a dermoid or a dermoid cyst. I suggest you consult a pediatric surgeon regarding this. Regards - Dr. Sumanth </s>
