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.
Kidney Cysts, also called renal cysts, are round thin-walled sacs or pouches on the kidneys that usually contain liquid. They may vary widely in size, but most are often small. Some are present at birth (congenital), and others are caused by tubular obstructions. Typically, only one cyst occurs on the surface of a kidney, but multiple cysts can affect one or both kidneys. In most cases, the cysts are almost always benign (not cancerous) that rarely cause complications. Treatment is not normally required.
