Baby Has A Bump On Skin. Could Be An Inflammed Sebaceous Gland Or Lipoma. Shall I Do Biopsy?

Thank you for posting your query.
I understand your concern.
To be able to help you better I would like to know a few more details about the lump you have describe.
I want you to see if the lump is painful and mobile side to side.
If painful, surely may need antibiotics or a needle drain or other prcedure.
If painless and mobile side to side, its likely to be what you described, both of which dont need urgent therapy. sebaceous cyst is unlikely at 4 week age.
If it is nonmobile side to side, its likely to eb bone ro stuck to bone or vertebra, when it may be called gibbus and may need at least a xray to confirm the diagnosis.
Do write back with the reports. If the lump is little larger, an ultrasound will solve the mystery.
Awaiting your reply.
Regards.


Thank you for the clarification.
I agree with you. this is not an uncommon thing. It is harmless unless painful and fixed. It is definitely not likely to go away or grow.
Curiosity on part of safety will need biopsy or removal by surgery. As its not an emergency, it is totally a wish of parents to do something or nothing in such situations, both are safe in current situation.
Hope I have answered all your concerns. You are most welcome to write back if you have any doubts. I would be more than happy to help you.
Please accept the answer if you do not have any further queries.
Wishing your baby good health.
Regards.

Thank you for writing back.
Yes there is a difference. Both doctors have expressed their individual opinion.
Sebaceous gland is a gland in the skin that secretes sebum or sweat, if its' opening is blocked it gets bigger and firmer with little softness inside. Sebaceous glands may get painful and infected.
Lipomas usually do not get infected, and they are made up of fat. sebaceous gland has a small dimple over skin but lipomas generally do not have this dimple.
Whatever name we may give, if it is painless and mobile, therapy would be same.
I'm really sorry to say this, it is impossible to suggest any particular diagnosis without a physical examination. So without having the luxury of examining your baby I can simply not be opinionated.
Hope I have answered your query. Do write back to me if you have any doubts.
Wishing you good health.
Regards.
