Ask Question

Hodgkin Lymphoma (E)

The correct answer is E. Hodgkin lymphoma, because this young patient presents with the classic triad of superior vena cava (SVC) syndrome (facial plethora, jugular venous distention, chest wall venous engorgement), painless cervical lymphadenopathy, and the pathognomonic Hocken sign (alcohol-induced pain in lymph nodes), which is highly specific for Hodgkin lymphoma.

Why Hodgkin Lymphoma is Correct

This 23-year-old man demonstrates SVC syndrome with:

  • Facial flushing and feeling of head pressure/heaviness
  • Distended jugular veins
  • Anterior chest wall venous engorgement
  • Dyspnea and mental confusion (from venous congestion)

The key distinguishing features pointing to Hodgkin lymphoma are:

  1. Palpable, nontender cervical lymphadenopathy - Classic presentation of lymphoma 1
  2. Alcohol-induced neck pain (Hocken sign) - This is pathognomonic for Hodgkin lymphoma, occurring in 5-10% of cases
  3. Young age (23 years) - Hodgkin lymphoma has a bimodal age distribution with peaks in the 20s and after age 55
  4. SVC syndrome from mediastinal lymphadenopathy - Lymphoma accounts for approximately 8% of malignant SVC syndrome cases 2

The guidelines confirm that bulky mediastinal adenopathy can compress the SVC, causing facial edema, plethora, dilated neck veins, and prominent venous patterns on the chest 1. Recent case reports specifically document Hodgkin lymphoma presenting with SVC syndrome in young patients, with alcohol-induced pain being a distinguishing feature 3, 4.

Why the Other Options are Incorrect

A. Polycythemia vera is incorrect because while it can cause facial plethora, it does not cause:

  • SVC syndrome with venous obstruction
  • Painless lymphadenopathy
  • Alcohol-induced pain
  • The acute presentation described here typically presents with hyperviscosity symptoms, pruritus after bathing, and splenomegaly rather than mediastinal masses.

B. Bronchogenic lung cancer is incorrect because:

  • While lung cancer is the most common cause of SVC syndrome overall (accounting for 46% of cases - 22% small cell, 24% non-small cell) 2, it is extremely rare in a 23-year-old
  • Only 2 years of smoking history is insufficient for lung cancer development
  • Lung cancer does not cause alcohol-induced pain
  • The presence of bilateral, painless cervical lymphadenopathy is not typical for primary lung cancer in this age group 1

C. Cirrhosis of the liver is incorrect because:

  • Social drinking does not cause cirrhosis in a 23-year-old
  • Cirrhosis does not cause SVC syndrome, cervical lymphadenopathy, or mediastinal masses
  • Portal hypertension from cirrhosis affects the inferior vena cava system, not the superior vena cava
  • There are no stigmata of chronic liver disease mentioned (spider angiomata, palmar erythema, ascites)

D. Pulmonary embolism is incorrect because:

  • PE does not cause cervical lymphadenopathy or SVC syndrome
  • PE presents with acute dyspnea, pleuritic chest pain, and hemoptysis, but not with facial plethora, jugular venous distention, or chest wall venous engorgement 5, 6
  • The clinical presentation lacks typical PE risk factors (recent surgery, immobilization, DVT) 6
  • PE does not cause alcohol-induced pain or the progressive symptoms described

Clinical Pearls

Hocken sign (alcohol-induced lymph node pain) occurs within minutes of alcohol consumption and is seen in 5-10% of Hodgkin lymphoma patients. While the mechanism is unclear, it is highly specific when present.

SVC syndrome in young patients should immediately raise suspicion for lymphoma (Hodgkin or non-Hodgkin) or germ cell tumors, as lung cancer is exceedingly rare in this age group 2.

The combination of painless lymphadenopathy + SVC syndrome + young age makes lymphoma the overwhelming favorite, with the alcohol-induced pain clinching the diagnosis of Hodgkin lymphoma specifically.
