A tummy tuck may be possible with morphea, but it should not be treated as a routine clearance question. The key issues are whether the morphea is truly inactive, whether the planned incision or skin tightening would involve affected skin, and whether there is a higher risk of poor wound healing, widened scarring, delayed healing, or a flare after surgical trauma. Before surgery, I would want clearance from the dermatologist or rheumatologist who manages your morphea and lichen sclerosus history, plus an in-person exam by the plastic surgeon. Ideally the disease should be stable and quiet for a meaningful period, and the surgeon should review where the plaques are in relation to the planned incision and tissue removal. If there is active disease, fragile skin, or uncertainty about the diagnosis, it is safer to postpone until the skin condition is clearly stable.
