To the Editor.—
In the September 1982 Archives (118:660-662), Vanderveen et al stated that combination therapy with methotrexate and etretinate may be useful in the treatment of severe psoriasis by providing a controlled transition from methotrexate to etretinate therapy alone. They based their suggestion on the report of a single case. I report herein a case of severe, life-threatening hepatitis that occurred in a patient when concurrent therapy with methotrexate and etretinate was undertaken.
Report of a Case.—
A 47-year-old woman had had psoriasis since the age of 19 years and had been receiving methotrexate therapy since 1971. She had taken a weekly divided intermittent oral dosage of the drug. In November 1979, a liver biopsy specimen showed only mild fibrosis and slight Kupffer's cell proliferation. In addition to methotrexate therapy, the patient had received 248 psoralens and UV-A (PUVA) treatments from January 1976 to April 1980, taking 20 mg
