A deposition of myxoid material (arrow) was present between the tumour cells and in microcystic spaces (C, hematoxylin and eosin, original magnification, x20). Immunohistological studies showed positive staining for glial fibrillary acidic protein (D, GFAP, original magnification, x10). The Ki67 labelling index (E, Ki67, original magnification, x20).
