Methotrexate induced skin toxicity in chronic plaque psorias
Low-dose methotrexate is a well-tolerated and inexpensive systemic immunosuppressive agent used commonly in dermatology. However, several adverse events such as pancytopenia, pneumonitis, mucositis, and cutaneous ulcerations may develop during acute toxicity with dose-dependent or idiosyncratic mechanisms.

Risk factors for methotrexate toxicity include advanced age, hypoalbuminemia, renal dysfunction, and concomitant drugs increasing the level of methotrexate in the body.
