Question

Stellate granuloma is seen in:

• A. Sarcoidosis
• B. Cat scratch disease
• C. Cryptococcosis
• D. Histoplasmosis

Hint:

A star-shaped suppurative granuloma from a Bartonella infection.

Answer 1

The Correct Option is B

Step 1: Anchor on the descriptor stellate granuloma, which means a star-shaped focus of suppurative necrosis rimmed by palisading histiocytes. Step 2: This pattern is classically produced by Bartonella henselae in cat scratch disease, where infected lymph nodes develop central necrosis with neutrophils. Step 3: The same suppurative stellate appearance is shared by lymphogranuloma venereum, but among the choices given only cat scratch disease fits. Step 4: Sarcoidosis gives tight non-caseating epithelioid granulomas, and the fungal infections cryptococcosis and histoplasmosis give organism-laden granulomas without the stellate neutrophilic core, so the answer is cat scratch disease.\[\boxed{\text{Cat scratch disease}}\]
