Methotrexate cutaneous ulceration is commonly preceded by dosage mistakes, absence of folic acid supplementation, and concurrent use of nephrotoxic medications. Renal impairment, pancytopenia, and absence of folic acid supplementation are key risk factors for mortality from this adverse medication reaction. Providers should regularly monitor methotrexate dosing adherence, drug-drug interactions, and perform routine laboratory evaluation. Index of suspicion for this toxicity should remain high given the varied clinical presentation and high mortality.
