title: Hepatic angiosarcoma arising in an adult mesenchymal hamartoma.
abstract: Embryonal (undifferentiated) sarcomas arising in mesenchymal hamartoma are on record but cases of hepatic angiosarcoma (AS) arising in mesenchymal hamartoma (MH) of the liver are extremely rare. We report one such case in a 20-year-old male patient. He presented with a lump in the right hypochondriac region and pain of two years duration with rapid increase in size since two months. Ultrasonography (USG) revealed a well circumscribed mass on the undersurface of the right lobe of liver suggestive of hemangioma. The patient underwent resection of the mass. Histopathology revealed AS with areas of MH.
