title: [Histopathological study of a recurrent malignant glioma after an intratumor local injection of adriamycin].
abstract: This paper presents interesting morphological findings, which have never been previously reported, on tumor tissues after a local injection of an anticancer agent into three patients with malignant glioma. Following a craniotomy, 0.5 mg of Adriamycin (ADM) was injected through an Ommaya reservoir into the tumor bed. Light microscopy of the recurrent tumor and surrounding necrotic tissue revealed massive coagulation necrosis of the tumor tissues and fibrinoid necrosis of vascular channels, centering at the tip of the Ommaya tube. In the surrounding area of the massive coagulation necrosis, considerable reactive collagenous tissue, infiltrating lymphocytes and foreign body giant cell were found as well as so-called "organized" necrotic tissue. Electron microscopic findings of the same specimens revealed deposits of lipofuscin, lipid droplets, lysosome, abundant myelin figures and fibrous strands. It can therefore be assumed that this or similar anticancer agents, when may be directly incorporated into the residual tumor cells, are apparently reduced by coagulation necrosis and reactive collagenous tissue.
