Hi
Welcome to the MedHelp forum!
A lump on the scalp can be a part of the skull structure. Sometimes the skull bones have an exaggerated curvature or protuberance without any cause. Otherwise it can be an osteoma which is a bone tumor. If you hit your head somewhere long back, then this could be a localized tight hematoma. It can also be a localized collection of nerve and fibrous tissue called neurofibroma or it can be a localized contusion or a lipoma. It cannot be a lymph node as scalp does not have any.
Since the lump is not causing any symptoms, it should not be touched often. However, you must consult a doctor and find out what exactly it is by X-ray of skull or a CT scan. Take care!
