🎗️ Lymphoma: A Brief Overview
Lymphoma is a cancer of the lymphatic system that arises from abnormal proliferation of lymphocytes (a type of white blood cell).
🔹 Main Types
1. Hodgkin Lymphoma
* Characterized by the presence of Reed–Sternberg cells.
* Commonly affects young adults.
* Often spreads in a predictable, contiguous pattern.
2. Non-Hodgkin Lymphoma
* A diverse group of lymphoid cancers.
* Can occur at any age.
* Usually has a less predictable pattern of spread.
🔹 Common Clinical Features
✅ Painless enlargement of lymph nodes (neck, axilla, or groin)
✅ Unexplained fever
✅ Night sweats
✅ Unintentional weight loss
✅ Fatigue and weakness
These are collectively known as “B symptoms.”
🔹 Diagnosis
🔍 Lymph node biopsy (gold standard)
🔍 Complete blood count (CBC)
🔍 Serum LDH
🔍 CT scan or PET-CT for staging
🔍 Bone marrow examination when indicated
🔹 Treatment
💉 Chemotherapy
💉 Immunotherapy
💉 Radiotherapy
💉 Stem cell transplantation in selected cases
🎯 Clinical Pearl
“Painless lymphadenopathy with B symptoms should raise strong suspicion for lymphoma until proven otherwise.”
High-Yield Exam Fact
A patient with enlarged painless lymph nodes, fever, night sweats, and weight loss should always be evaluated for lymphoma, especially if symptoms persist for weeks to months.
