[Malignant fibrous histiocytoma of the neck with metastases to the brain].

A case of malignant fibrous histiocytoma with multiple brain metastases in a 48-year-old man is described. The tumour (5 X 6 cm in size) located under m. sternocleidomastoideus, surrounded inner carotid artery and grew into its wall. Pseudoaneurysm (4 X 5 cm in size) with thrombosis was found 2 cm over the tumour. There were multiple metastases (from 1 to 3 cm in diameter) in the right brain hemisphere. The tumour consisted of fibroblast-like cells, polymorphic histiocyte-like cells, with one or several nuclei, Touton cells, and osteoclast-like cells and groups of xanthoma cells.
