Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Cat scratch disease is a bacterial infection caused by Bartonella henselae, acquired from the scratch of an infected cat or kitten. Step 2: It produces a granulomatous lymphadenitis. The regional lymph nodes show follicular hyperplasia with central stellate (star-shaped) areas of necrosis containing neutrophils, surrounded by palisading histiocytes (a suppurative granuloma). Step 3: This stellate or stellate-shaped suppurative granuloma is the characteristic histological clue. Step 4: Sarcoidosis shows non-caseating epithelioid granulomas, while cryptococcosis and histoplasmosis are fungal granulomas without this stellate suppurative pattern, so cat scratch disease is correct.
