Hi, a friend of mine's green iquana suddenly developed a raised round lump on its right side between the front and rear right legs. No apparent injury or swallowing of anything. The iquana appears sensitive when this lump is touched. Everything else normal, including feeding(variety of greens with calcium/mineral supplement), and good UV...seemed to pop up overnight. Without a pic right now I can say that this is a young animal about a foot in body length(without the tail), and the lump is about the diameter of a dime and raised about 1/4 inch. Any comments or help appreciated! Thanks
