title: Multiple eruptive dermatofibromas in a patient with dermatomyositis taking prednisolone and methotrexate.
abstract: Dermatofibroma (DF) is a common, benign, dermal tumor, often occurring as a single lesion. Multiple eruptive DFs are rare and usually associated with autoimmune diseases, immunosuppressant therapy, or both. We present the case of a 28-year-old woman with dermatomyositis who developed multiple eruptive DFs after undergoing methotrexate and corticosteroid treatment. Immunosuppressants such as methotrexate and corticosteroids might cause multiple eruptive DFs.
