[|Human|] Hello, I have a question, I have a large, hard lump on the back top of my head on the left side. Its not painful, and it doesnt move, I can move the skin around over it. It feels as hard as the rest of my skull and I first noticed it three years ago. I dont have any other symptoms. What could it be?
[|AI|]  Hi. Thanks for your query. Good explanation of the findings. Hard lump-skin moves- 3 years.IT is possibly coming from the bone as Osceola/ or a lipoma, appears hard here as it is in the confined space / The best way to get a correct diagnosis is HRCT scan of the area and FNAC. The decision to whom should be contacted depends upon the CT scan findings. IF feasible, get this operated. It is better to get this removed (excised) for 2 reasons.1> your get rid of the disease and 2> you get the histopathological diagnosis-makes you tension-free
