A 45-year-old woman with long-standing rheumatoid ahritis complains of dry eyes and dry mouth. Bilateral enlargement of the parotids is noted on physical examination. The syndrome described here is best described as
**Core Concept**
The syndrome described in the question is a classic example of a condition where there is an abnormal immune response leading to the inflammation and destruction of exocrine glands, particularly the salivary and lacrimal glands. This condition is commonly seen in patients with autoimmune diseases such as rheumatoid arthritis.
**Why the Correct Answer is Right**
The correct answer is Sjögren's syndrome, which is characterized by lymphocytic infiltration and destruction of the exocrine glands, leading to symptoms such as dry eyes (xerophthalmia) and dry mouth (xerostomia). This condition is often associated with autoimmune diseases such as rheumatoid arthritis, lupus, and scleroderma. The enlargement of the parotid glands (parotidomegaly) is a common clinical finding in Sjögren's syndrome.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the clinical scenario described.
* **Option B:** This option is incorrect because it is not a recognized syndrome associated with exocrine gland destruction.
* **Option D:** This option is incorrect because it is not a specific syndrome, but rather a general term for inflammation of the salivary glands.
**Clinical Pearl / High-Yield Fact**
Sjögren's syndrome is often associated with other autoimmune diseases, and patients with this condition are at increased risk of developing lymphoma. A thorough examination of the patient's medical history and laboratory tests is essential to diagnose this condition.
**Correct Answer:** C. Sjögren's syndrome
