A 23-year-old woman presents with cervical and mediastinal lymphadenopathy. Biopsy of a cervical lymph node reveals a nodular appearance with fibrous bands, effacement of the lymph node architecture, and numerous lacunar cells. Which of the following is true regarding this disorder?
**Core Concept**
The underlying condition described is consistent with **Hodgkin lymphoma**, specifically the **nodular sclerosis subtype**, which is characterized by the presence of **lacunar cells** and a distinct nodular pattern with fibrous bands. This subtype is the most common form of Hodgkin lymphoma, particularly in young adults.
**Why the Correct Answer is Right**
The description provided matches the **nodular sclerosis subtype** of Hodgkin lymphoma, which typically presents with **cervical and mediastinal lymphadenopathy**. The presence of **lacunar cells**, which are a type of **Reed-Sternberg cell**, and the **effacement of lymph node architecture** with **fibrous bands** are hallmark features of this subtype. The nodular pattern and the specific cell types are diagnostic clues that point towards this particular subtype of Hodgkin lymphoma.
**Why Each Wrong Option is Incorrect**
**Option A:** This choice is incorrect because it does not accurately describe the key features of the nodular sclerosis subtype of Hodgkin lymphoma.
**Option B:** Similarly, this option does not align with the characteristics of the condition described.
**Option C:** This choice is also incorrect as it fails to match the diagnostic findings presented.
**Option D:** This option is incorrect because it does not correspond to the specific features of the nodular sclerosis subtype of Hodgkin lymphoma.
**Clinical Pearl / High-Yield Fact**
A memorable point is that **Hodgkin lymphoma** often presents with **contiguous lymph node involvement**, and the **nodular sclerosis subtype** is particularly known for its **mediastinal involvement** and **young adult predominance**. Recognizing the **lacunar cells** and **fibrous bands** in a lymph node biopsy is crucial for diagnosis.
**Correct Answer:** D. The nodular sclerosis subtype of Hodgkin lymphoma is the most common form of Hodgkin lymphoma in young adults.
