Doughy skin and woody induration of tongue is seen in?
**Core Concept**
The question requires knowledge of a specific dermatological condition characterized by unique changes in skin texture and tongue induration. This condition is a manifestation of a systemic disease process.
**Why the Correct Answer is Right**
The correct answer is associated with scleroderma, a chronic autoimmune disease that affects the skin and other organs. The characteristic "doughy skin" and "woody induration of tongue" are due to the deposition of collagen and fibrosis in the affected tissues. This leads to a hardening and tightening of the skin and mucous membranes, causing the observed symptoms.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not match the clinical presentation of doughy skin and woody induration of the tongue. Scleroderma is a distinct entity with a specific set of symptoms.
**Option B:** This option is incorrect because it refers to a different condition altogether. While it may present with skin changes, it does not typically involve the tongue or the characteristic doughy texture.
**Option C:** This option is incorrect because it is not directly related to the symptoms described. Although it may cause skin changes, it does not specifically cause the observed tongue induration.
**Option D:** This option is incorrect because it is a different condition that may present with skin changes, but it does not typically involve the tongue or the characteristic doughy texture.
**Clinical Pearl / High-Yield Fact**
Scleroderma is a chronic autoimmune disease that affects multiple systems, including the skin, lungs, kidneys, and gastrointestinal tract. Early recognition and management are crucial to prevent organ damage and improve quality of life.
**Correct Answer:** C. Scleroderma.
