Pathological findings of Sjogren’s syndrome include all except:
**Core Concept**
Sjogren's syndrome is a chronic autoimmune disorder characterized by lymphocytic infiltration and destruction of exocrine glands, particularly the salivary and lacrimal glands. This leads to symptoms of dry mouth (xerostomia) and dry eyes (xerophthalmia). The pathological findings in Sjogren's syndrome involve a complex interplay of immune cells, cytokines, and glandular destruction.
**Why the Correct Answer is Right**
The hallmark pathological feature of Sjogren's syndrome is the presence of lymphocytic infiltrates in the affected glands. This is primarily driven by activated T cells, which release cytokines such as interferon-gamma and tumor necrosis factor-alpha, promoting inflammation and glandular destruction. The lacrimal gland and salivary gland are commonly affected, leading to impaired tear and saliva production.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is not a typical pathological finding in Sjogren's syndrome. While some systemic manifestations may occur, they are not a primary feature of the disease.
* **Option B:** This option is incorrect because it is not a characteristic pathological finding in Sjogren's syndrome. The disease primarily involves lymphocytic infiltration, not granulomatous inflammation.
* **Option C:** This option is incorrect because it is not a specific pathological finding in Sjogren's syndrome. While some patients may experience systemic manifestations, they are not a primary feature of the disease.
**Clinical Pearl / High-Yield Fact**
Sjogren's syndrome is often associated with other autoimmune disorders, such as rheumatoid arthritis, lupus, and scleroderma. Patients with Sjogren's syndrome are at increased risk of developing these conditions, and a thorough evaluation for co-existing autoimmune diseases is essential in the diagnostic workup.
**Correct Answer:** A.
