Malignant fibrous histiocytoma

From Felipedia

Malignant fibrous histiocytomas are a variant of fibrosarcoma and make up about 60% of the tumours of the feline fibrosarcoma complex.

These tumours are very polymorphic, with differences occurring not only between tumours but also within the same tumour. MFHs are characterised by the combined presence of mesenchymal and histiocytic neoplastic cells within a relatively abundant collagen stroma.

Subtypes of MFH have been recognised in relation to the presence of multinucleated giant cells (MFH with giant cells) or abundant myxoid stroma^[1].
