These tumours always take orighi frompigmented tissues (skin, choroid, pia mater), and are very malignant. ^ It is doubtful, however, whether the species of tumour which has been and isunderstood under this designation is in all cases one and the same. MIXED SARCOMA 93 The name chloroma is given to green-coloured tumours having thestructure of the round-celled sarcoma. The colour is due to smallgranules lying in the cells, which give the reaction of fat. 6.
