This lump can be;
2) Dermoid cyst
3) Osteoma; bony benign over growth common on face and skull bones.
All are benign and usually not need removal unless cause cosmetic concerns.
I am not sure what he meant with the 'a piece of gristle.'
Please feel free for your follow up questions.
Thank you for this helpful response. Could you answer one question please. What is the only way you could know which one of these it could be for sure? an ultrasound? or to remove a sample? I dont intend to pursue this, I am just interested how you could actually find out. Thanks.
You are most welcome,
An ultrasound would be the best modality. The other helpful measure can be x-ray and / or needle aspiration of the lump.
It is pleasure and privilege assisting you.
Finally, would you be absolutely rule out it being a swollen lymph node as it is above the ear?
You are very welcome,
It is very unlikely to be the site of a lymph node, so I would rule it out to be a lymph node.
Thanks. And the other thing I mentioned, which was the long, stringy ridge just underneath the lump, like a tendon. Can you have tendons in this area as the first GP suggested. I have these stringy tendons lower down just above the ear but are these the same things this high up?
No. There are no tendons at this place.
A blood vessel is a possibility. There is a blood vessel usually there.
