Regarding chalazion all are true, EXCEPT:
**Core Concept**
A chalazion is a benign inflammatory lesion of the eyelid, resulting from the obstruction of a meibomian gland. It is characterized by the accumulation of sebaceous material within the gland, leading to inflammation and swelling of the surrounding tissue.
**Why the Correct Answer is Right**
The correct answer regarding chalazion is related to its pathophysiology. A chalazion occurs when a meibomian gland becomes clogged, causing the sebaceous material to accumulate and leading to inflammation. This is often due to an increase in sebum production or a blockage of the gland's duct. The inflammation and swelling of the surrounding tissue are the body's response to this obstruction.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because chalazia are not typically associated with a viral infection. While viral infections can cause other types of eyelid lesions, such as blepharitis, they are not a primary cause of chalazia.
* **Option B:** This option is incorrect because a chalazion is not a type of malignant tumor. While chalazia can be confused with malignant tumors due to their similar appearance, they are a benign condition.
* **Option C:** This option is incorrect because a chalazion is not typically treated with antibiotics. While antibiotics may be used to treat secondary bacterial infections that can occur with a chalazion, the primary treatment is usually drainage or removal of the lesion.
**Clinical Pearl / High-Yield Fact**
It's essential to distinguish between a chalazion and a hordeolum (stye), as both conditions can cause eyelid swelling and redness. A hordeolum is a bacterial infection of the eyelid margin, often caused by Staphylococcus aureus, whereas a chalazion is a benign inflammatory lesion of the meibomian gland.
**Correct Answer: B. A chalazion is not a type of malignant tumor.**
