Hematology/Oncology Lymph Node Seminar for Medical II Students

Slides 1A-C Normal Lymph Node with Reactive Follicular Hyperplasia

Identify:

• capsule
• subcapsular sinus
• follicles (germinal centers and mantle zones)
• interfollicular zone (paracortex)
• medullary sinuses (sinuses are more easily identified on slide 7)
• B-cell and T-cell areas of the lymph node

Discussion:

1. What architectural changes occur with reactive processes in the lymph nodes?
2. Compare the pattern expected from a predominantly B-cell reaction (humoral immune response) with a predominantly T-cell process (cell-mediated immune response).
