Nodular scleroderma in systemic sclerosis under D-penicillamine therapy.

A case of systemic sclerosis (SS) which developed keloidal lesions (nodular scleroderma) on the chest during D-penicillamine (DPC) therapy is reported. The 36-year-old woman showed rapidly progressing skin sclerosis with lung and esophageal involvement, and DPC was started at the age of 38. Skin sclerosis as a whole had improved to some extent, when keloidal nodules developed on the upper chest at the age of 44. Since there were no other findings suggestive of adverse reactions caused by DPC, we speculate that activation of the fibroblasts in these lesions occurred despite the suppressive effect of DPC.
