* Goodpasture’s syndrome is an autoimmune disorder caused by antibodies that attack the basement membranes of renal glomeruli and/or respiratory alveoli; specifically, the antibodies attack type IV collagen in the tissues.
— In a histological sample of an affected glomerulus, we can see the characteristic crescent-shaped area formed by excessive fibrin and cellular material.
— In a sample of lung tissue, we highlight hemorrhaging in the inflamed alveoli.
— Goodpasture’s syndrome may be treated with corticosteroids and cyclophosphamide, or plasmapheresis, which removes the attacking antibodies.
