This looks like the result of a chronic trauma or infection creating a proliferative skin inflammation (that is why it looks like a lump). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths.
