Undefined: presence of a lump defined by a lesions size, pain, mobility. It could be a cartilaginous lesion growing off the lower edge of the rib, or a benign muscular process in the abdominal wall where the rectus abd. reaches the rib. A needle aspiration under local can resolve the issue in most instances
