Abstract:
Numerical density of vessels in axillary lymph node structures in breast cancer patients was studied by light microscopy with antibodies to CD34. The correlation between the stage of breast cancer and vascularization of lymph nodes was analyzed. The development of breast cancer was followed by rapid and significant increase in the number of blood vessel in axillary lymph nodes in general and in all their specific areas, especially in the paracortex and medullary substance. Strong or very strong positive correlation between the stage of tumor process and parameters of vascularization was observed in various areas of the axillary lymph nodes. No significant differences in node vascularization were observed between women without breast cancer and women with stage I breast cancer; the differences were found only starting from stage II. Considerable vascularization of lymph nodes can be a symptom of malignant tumor growth in the area of lymph collection. The duration of the tumor process and the size of the tumor can be indirectly evaluated by the increase in vessel number in lymph nodes.

From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
01:15Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
