A nurse is assessing a 28-year-old patient who has been diagnosed with Hodgkin's lymphoma. What is the most characteristic assessment finding in a patient with Hodgkin's lymphoma?

## 보기

1. Severe bone pain and pathological fractures
2. Petechiae and spontaneous bleeding episodes
3. Painless, enlarged lymph nodes in the neck or chest **✔ 정답**
4. Severe fatigue with rapid onset of symptoms

**정답: 3**

## 해설

Painless lymphadenopathy in the neck or chest is the hallmark sign of Hodgkin's lymphoma, present in 90% of cases. Other options represent symptoms more typical of other conditions like multiple myeloma, thrombocytopenia, or non-Hodgkin lymphoma.

Key Characteristic of Hodgkin's Lymphoma

The hallmark clinical presentation of classic Hodgkin lymphoma (cHL) is the insidious onset of painless, enlarged lymph nodes, most frequently located in the cervical (neck) or supraclavicular/mediastinal (chest) regions. This finding is directly linked to the underlying pathophysiology of the disease, where malignant Reed-Sternberg cells accumulate within lymphoid tissues, causing nodal expansion without associated infection or acute inflammation that would typically cause tenderness [1]. This distinguishes it from lymphadenopathy due to infectious processes, which is often painful.

Pathophysiologic Basis and Pre-diagnostic Window

The neoplastic cells in cHL secrete high quantities of thymus- and activation-related chemokine (TARC). Research has demonstrated that serum TARC levels can be strikingly elevated as early as 6 years before a clinical diagnosis is made [1]. This prolonged pre-diagnostic phase, characterized by a specific biomarker elevation, explains why the disease process is often subclinical for an extended period before the lymph nodes enlarge sufficiently to be palpated or cause symptoms. The slow, progressive accumulation of malignant cells and the localized cytokine-driven environment contribute to the painless nature of the lymphadenopathy.

Clinical Context and Diagnostic Challenges

The indolent nature of this presentation can create a diagnostic challenge in primary care. The systemic inflammatory response induced by the lymphoma itself can mimic other conditions. Evidence shows an increase in healthcare utilization and prescribing patterns in the years prior to a cHL diagnosis. Specifically, there is a noted increase in steroid prescribing [2] and inflammatory marker testing (such as C-reactive protein and erythrocyte sedimentation rate) [3] in the year before diagnosis. This reflects the clinical reality that patients often present with non-specific symptoms like fatigue, pruritus, or low-grade fever, which may be initially attributed to allergic or inflammatory conditions. The presence of a persistent, painless, rubbery lymph node, particularly in a young adult, must prompt a thorough evaluation to differentiate this malignant process from benign reactive conditions.References (research sources)

## 임상 시나리오

Assessing Painless LymphadenopathyKey Clinical Guide for Suspected Hodgkin Lymphoma
The hallmark of classic Hodgkin lymphoma is a painless, rubbery, enlarged lymph node, most often found in the cervical or supraclavicular region. This differs from the tender nodes typical of infection.

A mediastinal mass is the second most common presentation. Assess for subtle signs like a persistent, non-productive cough, dyspnea, or superior vena cava syndrome (facial swelling, distended neck veins).

CautionDo not dismiss an isolated, non-tender node as benign. B symptoms (fever, night sweats, weight loss >10% in 6 months) may be absent in early disease. An excisional biopsy is essential for diagnosis.

## 핵심 개념

- **Reed-Sternberg cells** — Large, abnormal B lymphocytes that are the malignant hallmark of classic Hodgkin lymphoma, causing lymph node enlargement.
- **Lymphadenopathy** — Enlargement of lymph nodes, which in Hodgkin lymphoma is typically painless, firm, and rubbery.
- **B symptoms** — Systemic symptoms of lymphoma including unexplained fever, drenching night sweats, and unintentional weight loss.
- **Mediastinal mass** — A common site of lymph node enlargement in Hodgkin lymphoma, often found on chest imaging and may cause cough or dyspnea.
