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.
Simple kidney cysts are different from the cysts that develop when a person has polycystic kidney disease (PKD), which is a genetic disorder. Simple kidney cysts do not enlarge the kidneys, replace their normal structure, or cause reduced kidney function like cysts do in people with PKD.
