Pectus carinatum

Pectus carinatum, also known as "pigeon chest," is a chest wall deformity where the breastbone (sternum) protrudes outward instead of lying flat. It occurs due to abnormal cartilage growth between the ribs and sternum, causing the chest to bulge. Can be congenital (present at birth) or develop during adolescence. More common in males. Often associated with conditions like Marfan syndrome or Ehlers-Danlos syndrome. May be linked to genetic factors.
