I ve had this hard cyst-like bump on my stomach (lower left rib area) ever since I could remember. Its about half to 3/4 of the size of a pencil eraser and oval shaped. It is almost flesh colored as it is only a shade or two darker than my skin . I felt a hair growing out of it and noticed that there was a brownish-black spot on it. It doesn t hurt or itch. The bump itself isn t that fair raised above my skin. When I tug at my skin, it moves with it. What could it be? A cyst? A mole? Can a cyst have black spots on it?
