## Core Concept
Acute sarcoidosis, also known as Löfgren's syndrome, is a form of sarcoidosis that presents acutely with symptoms such as bilateral hilar lymphadenopathy, erythema nodosum, and joint symptoms. The treatment primarily focuses on managing symptoms and modulating the immune response.

## Why the Correct Answer is Right
The correct answer, **Corticosteroids**, is the treatment of choice for acute sarcoidosis due to their potent anti-inflammatory and immunosuppressive properties. Corticosteroids can effectively reduce inflammation, alleviate symptoms, and promote resolution of the disease. They are particularly useful in managing symptoms such as erythema nodosum and joint pain, and in reducing the extent of lung involvement.

## Why Each Wrong Option is Incorrect
* **Option A:** NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) may provide symptomatic relief for mild cases of acute sarcoidosis but are not sufficient as standalone treatment for more severe or acute presentations.
* **Option B:** Antibiotics are not typically used in the treatment of sarcoidosis as it is not caused by a bacterial infection.
* **Option D:** Immunosuppressants other than corticosteroids (such as methotrexate) may be considered in certain cases of sarcoidosis that are refractory to corticosteroids or as steroid-sparing agents, but they are not the first line of treatment for acute sarcoidosis.

## Clinical Pearl / High-Yield Fact
A key point to remember is that Löfgren's syndrome, a form of acute sarcoidosis, often resolves spontaneously within 2-6 months, but corticosteroids can significantly alleviate symptoms and are usually the first line of treatment for symptomatic relief.

## Correct Answer: C. Corticosteroids
