Other variants of DFSP include pigmented (also known as Bednar tumor) DFSP, myxoid DFSP, DFSP with myoid differentiation, plaquelike DFSP, giant cell fibroblastoma (juvenile form of DFSP), and fibrosarcomatous
Histological variants include fibrosarcomatous
type, pigmented type and myxoid type.
These include Bednar tumour, fibrosarcomatous
with myoid/myofibroblastic change, myxoid, granular cell, palisaded, giant cell fibroblastoma, combined and indeterminate.
Histologically, MFH exhibits a diverse cellular composition, as the fibrosarcomatous
and histiocytomatous elements of the tumor are present in a mixed fashion.
