Found this which is quite intresting - a girl saying her horse has lumps over his body and more so under the saddle.
Dear Alison These rather unsightly lumps are called nodular skin disease ( also known as collagen necrosis). They sound quite harmless and, generally speaking, never cause a problem. But they do look unsightly. Most lumps develop under the saddle, and I have seen horses with upto 40-50 on its back. However, providing they are painless to touch and they don't grow in size, I wouldn't be at all worried about them. We have tried removing such lumps in the past, and having histopathology done on the lumps. However this has not helped us either in the diagnosis or the treatment. Very occasionally, the odd lump will break through the skin (ulcerate) and become quite painful, red and sore. These were common in the work horses in the past, and were called Sitfasts. When they get to this stage, the only resolution is by cutting them out. Nodular skin disease, because of its unsightliness, is a big problem in show horses, and the only treatment I have found to be any use at all is by using a steroid based cream and massaging it into the offending lumps on a daily basis for two to three weeks. There appears to be a seasonal basis to these lumps, and they seem to appear in the spring and the autumn. It is thought that, although they are related to tack, sweating, the sweating in these areas created by the tack may be a factor. So the rule of thumb is, if they are not painful to touch, and they are not growing, they are best left well alone. Best wishes, Stuart
