Definition / general
- Due to controversy over the precise lineage of these tumors, these tumors are termed "so called" fibrohistiocytic tumors (Fletcher, WHO Classification of Tumours of Soft Tissue and Bone, 2013)
- Tumors previously called MFH (malignant fibrous histiocytoma) are now called undifferentiated or unclassified sarcoma; they are subclassified based on cell morphology: undifferentiated pleomorphic sarcoma, spindle cell, epithelioid cell and round cell
