Yes : Yes - one of the side effects to corticosteroid (i.e. Cortisone) injections is lipoatrophy. Lipoatrophy is the medical term for loss of fat under the skin. The steroid medicine can dissolve the fat under the skin and cause a depression, or scar. It can also affect the cells that make pigment, so that the overlying skin can look lighter. This side effect typically occurs several months after the injection and can progress, somewaht, over several months. In many patients, the area can fill back in with fat cells, but this can take several years. It is purely a cosmetic blemish and may very well improve with time.
