Classical markers for Hodgkin’s disease –
**Core Concept**
Hodgkin's disease, also known as Hodgkin lymphoma, is a type of cancer that affects the immune system, specifically the lymphatic system. The diagnosis and classification of Hodgkin lymphoma involve the identification of specific **cell surface markers** and **histopathological features**.
**Why the Correct Answer is Right**
Although the exact answer choice is not provided, classical markers for Hodgkin's disease typically include **CD15** and **CD30**, which are expressed on the surface of **Reed-Sternberg cells**, the hallmark cells of Hodgkin lymphoma. These markers are crucial for the diagnosis and differentiation of Hodgkin lymphoma from other types of lymphoma.
**Why Each Wrong Option is Incorrect**
**Option A:** Without knowing the specific options, it's challenging to provide detailed explanations. However, incorrect options might include markers that are not specific to Hodgkin lymphoma or are associated with other types of cancer.
**Option B:** Similarly, this option might be incorrect if it includes markers that are not typically associated with Hodgkin lymphoma.
**Option C:** This option could be incorrect if it includes markers that are more commonly associated with non-Hodgkin lymphoma or other cancers.
**Option D:** This option might be incorrect for similar reasons, lacking the specificity for Hodgkin lymphoma.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the presence of **CD15** and **CD30** on **Reed-Sternberg cells** is a diagnostic hallmark of classical Hodgkin lymphoma.
**Correct Answer:** Correct Answer: D. CD15 and CD30.
