**Core Concept**
Nodulocystic acne is a severe form of acne characterized by large, painful nodules and cysts on the skin, often leading to scarring. It is often resistant to topical treatments and requires systemic therapy.
**Why the Correct Answer is Right**
The correct answer for treating nodulocystic acne is **Isotretinoin**. Isotretinoin is a retinoid derivative that works by reducing sebum production, preventing the formation of comedones, and decreasing inflammation. It also has anti-inflammatory properties that help to reduce the size and number of nodules and cysts. Isotretinoin is often used as a last resort in treating nodulocystic acne due to its potential side effects and the need for close monitoring.
**Why Each Wrong Option is Incorrect**
**Option A:** **Hormonal therapy** may be used to treat acne in women, but it is not the primary treatment for nodulocystic acne.
**Option B:** **Topical benzoyl peroxide** and **retinoids** can be used to treat mild to moderate acne, but they are not effective in treating severe nodulocystic acne.
**Option C:** **Systemic antibiotics** can be used to treat acne, but they are not the first-line treatment for nodulocystic acne and may not be effective in severe cases.
**Clinical Pearl / High-Yield Fact**
Isotretinoin can cause teratogenic effects and is contraindicated in pregnancy. Women taking isotretinoin must use two forms of birth control and undergo regular pregnancy testing.
**Correct Answer:** C. Isotretinoin
