Abstract:  Pityriasis lichenoides is an uncommon, benign skin disorder with two major variants: acute and chronic. Autoimmune hepatitis comprises heterogeneous forms of chronic hepatitis that are generally progressive and often fluctuating. Two major forms of this entity are recognized. Herein, we report the concurrence of pityriasis lichenoides chronica with type I autoimmune hepatitis in a child, which, to the best of our knowledge, has not been previously reported. Although it is hard to say whether an etiologic relationship or coincidental coexistence occurred between the two entities in our patient, some common mechanisms may be involved in both diseases.
