MACROSCOPIC DESCRIPTION - Right temporal brain tumour: Multiple grey tan friable pieces of tissues measuring 40 x 30 x 10mm in aggregate.
MICROSCOPIC DESCRIPTION: A cellular infiltrate displaying variable nuclear hyperchromasia, angularity and pleomorphism, frequent mitotic figures and scant cell bodies, accompanied by a delicate fibrillary matrix which in part has a mucoid quality. Accompanied by a rich vasculature, including thrombosis, perivascular hyalinisation and swelling and stratification of endothelium, the infiltrate is diffuse but for foci of palisading around occasional blood vessels or zones of necrosis. The lesion appears to reach the subarachnoid space. Part of the internal margin of the growth is present as a blurred interface with adjacent brain tissue.
