A 24-year-old girl presented with complaints of acne. On examination, multiple nodules, cysts and intercommunicating sinuses were seen. How will you treat her?
**Core Concept**
The patient's presentation is consistent with a diagnosis of nodulocystic acne, a severe form of acne characterized by large, painful nodules and cysts. Effective treatment involves a combination of topical and systemic therapies to reduce inflammation and prevent scarring.
**Why the Correct Answer is Right**
The treatment of choice for nodulocystic acne is a systemic antibiotic, specifically isotretinoin (Option C). Isotretinoin is a retinoid derivative that inhibits the production of sebum in the sebaceous glands, reducing the formation of acne lesions. It also has anti-inflammatory properties, which help to reduce the size and number of existing lesions. Additionally, isotretinoin can help to prevent scarring by reducing the size and number of comedones.
**Why Each Wrong Option is Incorrect**
**Option A:** Topical retinoids, such as adapalene or tretinoin, are useful in treating mild to moderate acne, but are not sufficient to control nodulocystic acne.
**Option B:** Systemic antibiotics, such as doxycycline or minocycline, can be used to treat acne, but are often used in combination with isotretinoin or other treatments for severe cases.
**Option D:** Hormonal treatments, such as spironolactone, may be used to treat acne in women, but are not typically used as a first-line treatment for nodulocystic acne.
**Clinical Pearl / High-Yield Fact**
Isotretinoin is a teratogenic medication, meaning it can cause birth defects if taken during pregnancy. Therefore, patients taking isotretinoin must use effective contraception and undergo regular pregnancy testing to prevent fetal exposure.
**Correct Answer:** C. Isotretinoin.
