"Pulmonary tumour thrombotic microangiopathy occurs when there are non-occlusive tumour cell microemboli with fibrointimal remodelling in small pulmonary arteries, veins and lymphatics. It rarely causes pulmonary hypertension."
"Thrombotic microangiopathy is a consequence of tumour cells metastasising to the distal tiny arterioles, venules and lymphatics of the lungs. The embolised cells induce an intravascular procoagulant effect resulting in fibrocellular overgrowth of the intima and vasoconstriction. Occasionally, this proceeds to overt pulmonary hypertension."
