Autoimmune hepatitis is an inflammatory liver disease characterized histologically by a dense mononuclaear cell infiltration of the portal tract, serologically by the presence of non-organ and liver specific autoantibodies and increased concentrations of IgG in the absence of a known etiology. Two types of autoimmune hepatitis are classified in the peripheral blood of antinuclear antibody and/or in antismooth muscle antibody (ANA/ASMA) or liver-kidney microsomal type 1 antibody (LKM-1). Type I (ANA/ASMA positive) and type II (LKM-1 positive) autoimmune hepatitis in children have clinical, biochemical, and histologic differences. We have experienced a case of type I autoimmune hepatitis in a 9-year-old girl. She had shown highly elevated IgG, high serum transaminase and marked hepatosplenomegaly. And so serologically ANA and ASMA were positive, histological findings of the liver biopsy were compatible with chronic active hepatitis. She was medicated with prednisone, but symptoms did not improved. Now she is receving conservative regimens.

Odontogenic myxoma is a rare tumor which occurs almost exclusively in the jaws, and seems to be of odontogenic origin. Clinically this tumor tends to appear in the second and third decades of life, and most of the lesions are located in the premolar - molar region. It is characterized grossly by mucoid or gelatinous gray-whitish tissue that replaces the cancellous bone and expands the cortex. It is invasive locally and has a high recurrence rate ranging from 10% to 33%. Radiographically, the appearance of this tumor is varied, but usually appears as a unilocular or multilocualr radioluscency of varying size. We experienced a rare case of odontogenic myxoma 12 years old patient related to mandibular bilateral impacted canines in the mandible, so we report this case with literature.
