title: Primary myxoid leiomyoma of the liver.
abstract: We describe a case of hepatic leiomyoma in a 41-year-old woman who complained of abdominal discomfort due to a right upper quadrant abdominal mass. A computed tomographic scan revealed a large hepatic mass with unusual cystic change. Light and electron microscopic findings and an immunohistochemical study demonstrated diffuse and scattered proliferation of smooth muscle cells in a myxoid matrix. In contrast to previously reported cases of primary leiomyoma of the liver, the present tumor developed in a patient without an immunosuppressive condition. To the best of our knowledge, this is the first reported case of primary "myxoid" leiomyoma of the liver.
