Abstract
Fibrosis is characterized by the increased deposition of collagen and other matrix components by fibroblasts. This process occurs as a reaction to inflammation and is mediated by numerous cytokines including transforming growth factor beta (TGF-beta). Localized cutaneous scleroderma or morphea is characterized by fibrosis. Current treatment for morphea includes topical, intralesional, or systemic corticosteroids, vitamin D analog (calcitriol and calcipotriol), photochemotherapy, laser therapy, antimalarials, phenytoin, D-penicillamine, and colchicine, all with varying degrees of success. In this case report, imiquimod cream 5% (Aldara), which induces interferon and in turn inhibits TGF-beta, was employed to treat morphea.
