My niece is visiting and I have not seen her without a low neck shirt for about two months.  However, she stayed with me last night and she has this mass at the base of the skull about the size of a large orange and is soft to the touch.  It is growing rapidly.
Hi, dairy have gone through your question. I can understand your concern. She may have Desmond cyst, lipoma or some skin adnexal tumor in base of skull.  She should go for biopsy or fine needle aspiration cytology of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. 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.
