**Question:** For the following statements, select the most likely type of Hodgkin disease (HD). The only form of HD more common in women.

A. Classic Hodgkin lymphoma (HL)
B. Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL)
C. Primary mediastinal large B-cell lymphoma (PMBCL)
D. Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL)

**Correct Answer:** **D. Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL)**

**Core Concept:** Hodgkin disease (HD) is a group of lymphomas characterized by the presence of specific cell types called Hodgkin and Reed-Sternberg cells. There are two main types of HD: Classic Hodgkin lymphoma (HL) and Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a distinct entity and not considered Hodgkin disease.

**Why the Correct Answer is Right:** ENKTL is a type of lymphoma characterized by the proliferation of natural killer (NK) or T-cells, specifically in the nasal region. It is a non-Hodgkin lymphoma (NHL), not a Hodgkin disease.

**Why Each Wrong Option is Incorrect:**

A. Classic Hodgkin lymphoma (HL) and Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) are the two main types of Hodgkin disease, which is a specific group of lymphomas with the presence of Hodgkin and Reed-Sternberg cells.

B. Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a distinct entity but falls under the broader category of Hodgkin disease. It is characterized by the presence of Reed-Sternberg cells, which are characteristic of Hodgkin disease.

C. Primary mediastinal large B-cell lymphoma (PMLBCL) is a type of non-Hodgkin lymphoma (NHL) characterized by the proliferation of large B-cells in the mediastinum. It is not a Hodgkin disease.

D. Primary cutaneous T-cell lymphoma (PCTCL) is another type of non-Hodgkin lymphoma (NHL) characterized by the proliferation of T-cells. It is not a Hodgkin disease.

**Clinical Pearl:** Understanding the difference between Hodgkin disease and non-Hodgkin lymphoma is crucial for accurate diagnosis and treatment planning. Hodgkin disease is characterized by the presence of Hodgkin and Reed-Sternberg cells, while non-Hodgkin lymphomas are characterized by the proliferation of different lymphocyte subtypes.
