Summary

Digital ulcers in progressive systemic sclerosis (PSS) are often refractory to therapy. A frequently chronic aggressive course can lead to the loss of acral limbs involved. A 73-year-old woman developed a dramatic worsening of her ulcerations despite maximum conventional therapy. Switching therapy to bosentan and sildenafil, both in low-dose regimens, resulted for the first time in ten years in a complete healing of the ulcers. If substantiated in a series of patients, the additive and perhaps synergistic clinical benefits of combining bosentan and sildenafil may be a valuable option for the treatment of acral ulcers in PSS.
