Primary Malignant Fibrous Histiocytoma of the Liver: 2 Cases Report
Abstract
- The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to
a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern
and predominantly fibroblastic appearance. It was postulated that they were derived from
histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized
to be the most common sarcoma in the soft tissue of late adult life which involves the deep
fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs,
however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma
of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and
myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes
the clinical courses, characteristics and pathologic aspects with review of the related literatures.
