We report two female patients, aged 15 and 24 years old, who presented with mucositis, erythrodermia, pancytopenia, and elevation of hepatic enzymes. Plasma methotrexate levels confirmed the clinical diagnosis and both patients were treated with high leucovorin doses and management of associated complications. In one patient, pregnancy continued, giving birth to a newborn with cranial, face and limb malformations.

Considering the severity of complications and that patients may deny its use, when there is reasonable clinical suspicion of methotrexate intoxication, leucovorin treatment should be started.
