Abstract:
Renal angiomyolipomas (AMLs) are relatively common tumors containing fatty tissue, blood vessels, and muscular cells in various proportions. Typical AMLs can be diagnosed without histological confirmation by a combination of ultrasound and computed tomography imaging in up to 95% of cases. In contrast, simultaneous involvement of the kidney, renal vein, or lymph nodes is uncommon and might be confused with a metastasizing malignant tumor. We present a pathologically proven case of the very uncommon simultaneous involvement of the kidney and the lymph nodes in AML.

Detailed Structure and Function of 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...
