Dermatofibroma are common benign skin tumours that cause lumps in the skin and frequently cause concern upon discovery. The causes of dermatofibroma may include a reaction to trauma such as insect bites but the precise cause is often unclear.
Complex Renal Cysts. Kidneys are bean shaped organs and are an important part of the urinary system. The main function of the kidneys is to eliminate waste and toxins from the body. Sometimes due to over accumulation of toxins or calcium deposits, cysts can form in the kidneys.
Complex cysts pose a concern because a subset of complex cysts may have cancerous growth. Of note, most cancerous growths in the kidney are solid, not cystic. Yet some cancers of the kidney may have a cystic component. Strategies are available to predict whether a complex cyst may be associated with cancerous change.
