Malignant Fibrous Histiocytoma

Öz

Malignant fibrous histiocytoma is the mostly encountered soft tissue sarcoma around the seventh decade of life. Usually, it is located at lower ekstremities and deep in the muscles. It is seen in 4 histopathological subtypes, namely storiform pleomorphic, myxoid, giant cell and inflammatory types respectively. At this presentation, there are two malignant fibrous histiocytoma cases, one of storiform-pleomorphic and the other of giant cell types; the first located at the axillary region and the second located at the upper extremity subcutaneously. The first patient is 67 years of age and the second one is 71, both being males.

Malign Fibröz Histiositom

Öz

Malign fibröz histiositom, yedinci dekad civarında en sıklıkla görülen yumuşak doku sarkomudur. Genellikle alt ekstremitelerde ve kas içerisinde derin yerleşimli olan bu tümor, 4 histopatolojik tipte görülür. (Görülme sıklığına göre, storiform-pleomorfik, mikzoid, dev hücreli ve inflamatuvar tipler.) Bu sunumda biri aksilla, diğeri ise üst ekstremitede subkutan yerleşimli, ilki storiform-pleomorfik, ikincisi ise dev hücreli tipte iki malign fibröz histiositom olgusu yer almaktadır. Hastalardan ilki 67, ikincisi ise 71 yaşında olup, her ikisi de erkektir.
