Pectus Carinatum is a chest wall deformity in which the breastbone (sternum) and ribs protrude outward, giving the chest a forward-projecting appearance. It is commonly known as pigeon chest and usually develops during childhood or adolescence, especially during rapid growth periods.

This condition can cause both cosmetic concerns and, in some cases, breathing discomfort or reduced physical endurance. With early diagnosis and proper treatment, pectus carinatum can be effectively corrected without surgery in most cases.
