Limited cutaneous systemic sclerosis have the following characteristic autoantibody positivity:
**Core Concept**
Limited cutaneous systemic sclerosis is a subtype of systemic sclerosis, characterized by thickening of the skin and involvement of internal organs. The disease is associated with specific autoantibodies. **Autoantibody** positivity is a key diagnostic criterion.
**Why the Correct Answer is Right**
The correct answer is associated with **anti-centromere antibodies**, which are often found in patients with limited cutaneous systemic sclerosis. This subtype typically has a slower progression and less severe internal organ involvement compared to diffuse cutaneous systemic sclerosis.
**Why Each Wrong Option is Incorrect**
**Option A:** Is incorrect because it is associated with a different condition.
**Option B:** Is incorrect as it is related to diffuse cutaneous systemic sclerosis.
**Option D:** Is incorrect because it is not typically associated with limited cutaneous systemic sclerosis.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **anti-centromere antibodies** are highly suggestive of limited cutaneous systemic sclerosis, aiding in differentiation from other forms of systemic sclerosis.
**Correct Answer:** C. Anti-centromere antibodies.
