[|Human|] A tiny hard lump has developed under the skin at the top of my scalp.It does not hurt -- however my head itches like crazy -- so much so thatlately i have been applying anti-itch lotion to it.  What kind of a doctorshould I see.  I have moved and do not have a regular MD close by --I am worried because I have a sister who developed squameouscellcarcinoma in her mouth 10 years ago and it grew like crazy and shepassed away from it. But, with all the itching, hopefully mine is something less serious.  I have also had a terrible fingernail problemfor a year or so that I thought was just a dry skin condition, but nownot sure.  Can you lead me in the right direction.  I am not one toworry about my health, however my roommate felt the lump earliertoday and said I had better have a doctor see it.  Any advise isappreciated.Thanks.  Pat
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some Desmond cyst, skin adnexal tumor or some other lesion.  You should go for biopsy of that lump. It will give you exact diagnosis.  Then you should take treatment accordingly.  You should consult general surgeon first.  Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
