Abstract
|
|
|
Undifferentiated sarcoma of the liver is a highly malignant neoplasm that occurs
almost exclusively in children.
We present a case of adult undifferentiated sarcoma in a 33-year-old man. The
neoplasm was typically hypovascular on hepatic angiography and a globular, cystic and
mucoid mass separated from the adjacent liver by a pseudocapsule was removed from
the left lobe of the liver. Necrosis and hemorrhage were found. Microscopically the
neoplasm consisted of myxoid and cellular areas and the basic neoplastic cells were
stellate cells showing variable degree of anaplasia and pleomorphism. Eosinophilic
globules were PAS-positive and immunohistochemically negative for α-fetoprotein.
Extramedullary hematopoiesis was present and normal-appearing bile ducts and
hepatic cell cords were noted.
