- Sarcoidosis
- Cat scratch disease
- Cryptococcosis
- Histoplasmosis
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Translate the term: a stellate granuloma is a star-shaped, suppurative (neutrophil-filled) necrotic center ringed by palisading histiocytes inside a lymph node. Step 2: Link the morphology to its cause. This necrotizing lymphadenitis is the signature of cat scratch disease from Bartonella henselae transmitted by a cat scratch, accompanied by monocytoid B cells in the sinuses. Step 3: Contrast with sarcoidosis, whose granulomas are tidy, non-caseating, and lack the central neutrophilic necrosis that defines a stellate lesion. Step 4: The fungal options, cryptococcosis and histoplasmosis, form granulomas built around demonstrable yeast forms rather than a sterile-appearing stellate abscess. So the diagnosis pointing to a stellate granuloma is cat scratch disease. \[\boxed{\text{Cat scratch disease}}\]
