Brown induration
Brown Induration
Brown Induration (pronunciation: /braʊn ɪndjʊˈreɪʃən/) is a medical term referring to a condition characterized by the hardening and discoloration of an organ, typically the lungs, due to chronic venous congestion.
Etymology
The term "Brown Induration" is derived from the Latin words "indurare" meaning to harden, and "brunneus" meaning brown. This refers to the characteristic brownish coloration and hardening of the affected organ.
Pathophysiology
Brown Induration is often associated with congestive heart failure, where the heart's inability to pump blood efficiently leads to blood pooling in the veins. This results in increased pressure in the venous system, causing fluid to leak into the surrounding tissues. Over time, this fluid accumulation leads to tissue hardening or induration. The brown coloration is due to the accumulation of hemosiderin, a byproduct of red blood cell breakdown.
