**Core Concept**
Epimembranous deposition refers to the accumulation of immune complexes or other substances on the surface of cells, specifically on the epithelial basement membrane. This phenomenon is a hallmark of autoimmune diseases and can lead to inflammation and tissue damage.

**Why the Correct Answer is Right**
Epimembranous deposition is a characteristic feature of Goodpasture syndrome, a rare autoimmune disease caused by the presence of autoantibodies against the alpha-3 chain of type IV collagen. These autoantibodies bind to the basement membrane of the lung and kidney, leading to immune complex deposition and subsequent inflammation.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because epimembranous deposition is not typically associated with systemic lupus erythematosus (SLE), although SLE can involve the kidneys and lungs.
**Option B:** This option is incorrect because membranous glomerulonephritis involves subepithelial immune complex deposition, not epimembranous deposition.
**Option C:** This option is incorrect because diabetic nephropathy is characterized by thickening of the basement membrane, but not epimembranous deposition.

**Clinical Pearl / High-Yield Fact**
Goodpasture syndrome is a classic example of an autoimmune disease that can cause rapidly progressive glomerulonephritis and pulmonary hemorrhage. It is often associated with the presence of anti-GBM antibodies, which can be detected in the serum.

**Correct Answer:** D. Goodpasture syndrome.
