title: Immune disease expressed in liver and platelets in an adolescent: a case report.
abstract: We report a case of a 15-year-old boy with autoimmune hepatitis lacking common serologic markers and normal gammaglobulinemia associated with immune thrombocytopenia and family history of psoriasis. He presented to our department with a 4-year history of a cervical posterior lymphadenopathy and recent petechiae. Previous laboratory results 6 months before already showed hepatocellular injury. After exclusion of other causes, the diagnosis of autoimmune hepatitis was made based on clinical grounds, associated immune disorder and histological features of liver biopsy.The authors alert for this atypical presentation of autoimmune hepatitis and associated immune thrombocytopenia.
