[|Human|] hello I have had a small dime size lump on my head obviously under my scalp on an estimational guess 7-8 years. its on the right side up on top. it doesn t hurt in fact it can be moved around. its hard to a certain extent. I know about 7 to 8 years ago I picked at a scab there and kept picking at it til it was crater size I was wondering if by chance it could be hard scar tissue or possible calcium deposit of some sort. any advice would be great thank u.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some benign cyst like Desmond cyst. Or you may have some skin adnexal tumor. You should go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question. If you have any doubts then feel free to ask me. Thanks for using Chat Doctor. Wish you a very good health.
