From which region should preoperative lymph nodes for HLA typing be surgically obtained?

• A. Axillary region
• B. Cervical region
• C. Inguinal region
• D. Abdominal region

Answer: (C)

The correct answer is based on the anatomical and clinical considerations relevant to human leukocyte antigen (HLA) typing in transplant coordination. When preparing for organ transplantation, it is crucial to assess the HLA compatibility between donors and recipients. The inguinal region, which refers to the area groin, is significant because it contains lymph nodes that drain the lower extremities and pelvis. These lymph nodes can be reflective of the systemic immune response and can provide meaningful data regarding HLA typing. Inguinal lymph nodes are often less involved in direct surgical access issues compared to lymph nodes that are located in more complex anatomical areas. While the other specified regions—axillary, cervical, and abdominal—also have lymph nodes that can be sampled for HLA typing, the inguinal region is frequently chosen in clinical practices for its accessibility and the quality of the sample obtained. Understanding the source of lymph nodes is critical because they contribute essential immunological information for evaluating potential transplant compatibility, ensuring that the donor organ matches the recipient as closely as possible to reduce the risk of rejection.
