title: Pyoderma gangrenosum of the breast treated with low-dose cyclosporin A.
abstract: Pyoderma gangrenosum (PG) is a painful chronic ulcerative skin disorder often occurring in association with systemic disease. It typically affects the lower limbs, but may also involve other sites, or sometimes develop after trauma of surgical procedures. We report the case of a woman with rheumatoid arthritis who developed disfiguring and severe PG of the right breast, a rare site, following biopsy for a benign breast lesion, and who was subsequently successfully treated with low-dose cyclosporin A.
