Panniculus, sometimes referred to incorrectly as pannus, is a medical term describing a dense layer of fatty tissue growth, consisting of subcutaneous fat in the lower abdominal area. It can be a result of obesity and can be mistaken for a tumor or hernia. Abdominal panniculus can be removed during abdominal panniculectomy, a type of abdominoplasty. A panniculus can also be the result of loose tissues after pregnancy or massive weight loss.
