title: Cutaneous ulceration: an unusual sign of methotrexate toxicity--first report in a patient without psoriasis.
abstract: OBJECTIVE
  To describe a case of skin ulcer related to methotrexate toxicity.
  
  
  METHODS
  A 67-year-old white man with seronegative arthralgia developed recurrent skin ulcer concurrent with 3-year treatment with methotrexate 5 mg daily. The skin ulcer resolved on discontinuation of methotrexate.
  
  
  CONCLUSIONS
  To the best of our knowledge, this is the first reported case of skin ulcer believed to be induced by methotrexate in a patient without psoriasis.
  
  
  CONCLUSIONS
  Skin ulceration should be added to the list of possible toxic adverse effects of methotrexate, not only in psoriatic patients but also in those without psoriasis.
