Is this an osteoma-like bulge on my forehead? Advice? (photos)

This could be an osteoma or lipoma. If it is soft and movable, it is likely a lipoma. If it firm it may be an osteoma, An x-ray will help determine the answer. Osteomas can be removed easily from a small incision in the forehead hairline.

The most likely cause is a lipoma. It would be unusual for it to be an osteoma. An x-ray could determine if it's bony. And, yes, it's a simple office procedure to remove it.

An examination of you would be needed to try and determine what might be causing the mass on your forehead. I would say the most likely cause of a mass on the forehead would be a lipoma. Osteoma is another possibility. Lipomas and osteomas of the forehead can usually be removed surgically.

It's hard to tell if this is an osteoma from this photo, It would require a full exam. But if the appearance bothers you it can be easily addressed and removed. I do this often and it's a relatively small procedure. Best wishes.

How long have you had it? Was it induced by trauma? You might see a facial plastic surgeon and ask about it if it has been there for some time
