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.
Presentation: kidney cysts usually occur before liver cysts and chronic kidney disease is common. However, polycystic liver disease rarely leads to hepatic fibrosis and liver failure. Hepatomegaly and abdominal pain may be present. Cysts are usually first noticed during puberty.
