Hard solid lump on the left side of my forhead does it move i have had 2 separate consultations with a osteoma specialist surgeon both have said it is 100% not a osteoma they said it looks like how may forhead has formed? can i get this shaved down?

Possibly a firm Sebaceous Cyst. Common on the forehead.. Cannot just have it opened and squeezed . Need the sack surrounding all the sebum to be fully taken out as well

If it is a frontal bossing, it is just a cosmetic issue. You should consult a plastic surgeon to see if one would consider a surgical correction. Unless it is interfering with your daily life, I would not recommend surgery. Wish you good health!

If you have an obvious mass, you can have your local dr order an mri to determine the likely composition of the mass.
