A 65-year-old woman treated with etretinate for pityriasis rubra pilar
is developed chronic active hepatitis. The elevated transaminases were
noted 2 months after initiation of therapy and peaked 2 months after
discontinuation of etretinate. The spectrum of liver toxicity induced
by etretinate is reviewed. We suggest that reported cases of retinoid-
induced liver disease can be divided into four distinct categories: no
nspecific reactive hepatitis, acute hepatitis, chronic active hepatiti
s, and severe fibrosis or cirrhosis.
