Systemic embolization of mucous material

: Systemic embolisation of mucous substance occurs as a rare complication of mucinous carcinomas. A case of primary carcinoma of stomach is described with embolisation of mucus into cerebral, renal, pulmonary and myocardial vessels. Vascular blockade by mucus caused multiple partly haemorrhagic microinfarctions of the brain tissue. Beyond this, investigated tumour samples did not show any signs of angioinvasion and the production of mucus was far from massive.
