**Core Concept**
Eosinophilic abscess in lymph nodes is a rare condition associated with a specific type of parasitic infection. It is characterized by the presence of eosinophils and other inflammatory cells within the lymph node, often accompanied by the presence of a parasitic organism.

**Why the Correct Answer is Right**
The correct answer is associated with Loeffler's syndrome, which is caused by the migration of Ascaris lumbricoides (roundworm) through the lungs and into the lymph nodes. This results in the formation of eosinophilic abscesses within the lymph nodes. The eosinophils are attracted to the site of the parasitic infection, where they play a key role in the inflammatory response.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is not associated with eosinophilic abscesses in lymph nodes. Tuberculosis is a bacterial infection that typically causes caseating granulomas, not eosinophilic abscesses.
* **Option B:** This option is incorrect because it is associated with a different type of infection. Histoplasmosis is a fungal infection that typically causes granulomatous inflammation, not eosinophilic abscesses.
* **Option C:** This option is incorrect because it is not specifically associated with eosinophilic abscesses in lymph nodes. Cat-scratch disease is a bacterial infection caused by Bartonella henselae, which typically causes lymphadenopathy and granulomatous inflammation, but not eosinophilic abscesses.

**Clinical Pearl / High-Yield Fact**
Remember that eosinophilic abscesses in lymph nodes are often associated with parasitic infections, particularly those caused by nematodes (roundworms). This is a high-yield fact for exams, as it can help you to quickly identify the correct diagnosis in a case of eosinophilic lymphadenopathy.

**Correct Answer:** C.
