title: [A man with multiple mucosal lesions and pancytopenia].
abstract: A 57-year-old man came to the Emergency Department because of painful oral ulcers and skin lesions. He used methotrexate because of psoriasis, but he stopped using folic acid. Laboratory tests showed signs of dehydration and pancytopenia. We made the diagnosis 'methotrexate-intoxication'.
