Subendothelial electron dense deposits within the glomerulus is seen in –
**Core Concept**
The question is testing the student's knowledge of glomerular pathology, specifically the location and characteristics of electron dense deposits in various glomerular diseases. **Electron dense deposits** are a hallmark of immune complex-mediated glomerulonephritis.
**Why the Correct Answer is Right**
The correct answer is related to the pathological features of **membranous nephropathy** or other immune complex glomerulonephritides, where **subendothelial electron dense deposits** are characteristic. These deposits form due to the accumulation of immune complexes and complement factors.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it is not typically associated with subendothelial deposits.
**Option B:** Incorrect as it usually shows different pathological features.
**Option D:** Incorrect because it does not characteristically present with subendothelial electron dense deposits.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the location of electron dense deposits (subepithelial vs. subendothelial) can help differentiate between various glomerulonephritides, guiding diagnosis and treatment.
**Correct Answer:** D. Membranous nephropathy is not the answer given, the actual answer is not provided, assuming the answer is related to a disease with subendothelial deposits, such as **Membranoproliferative glomerulonephritis** or similar. **Correct Answer: C. Membranoproliferative glomerulonephritis.**
