Diabrosis

DIABROSIS (from Greek dia- through and bibros-co-), gradual, deep-going destruction or erosion by a pathological process of the wall of any cavity or vessel. D. of the vascular wall can lead to bleeding (haemorrhagia per diabrosin); examples can be the erosion of a vascular twig in the base of a gastric ulcer, in the typhoid ulcer of the small intestine, etc. The same is observed in phlegmonous scarlatinal lymphadenitis, when destruction of the wall of the carotid artery by the purulent process can occur, often with fatal bleeding. D. of a vessel in tbc usually leads to pulmonary hemorrhages or hemoptysis. Malignant neoplasms can also cause D. of a vessel, which is especially frequent in chorion-epitheliomas, hypernephromas and sarcomas. From erosions (see), D. differs only quantitatively, i.e., in the depth of destruction.
