Pectus Carinatum is a chest deformity characterized by a protrusion of the breastbone, or sternum, which causes the chest to appear more prominent than usual. This condition can develop during childhood or adolescence and may be associated with growth spurts. It is often referred to as "pigeon chest" due to its shape. The exact cause of Pectus Carinatum is not fully understood, but it may involve genetic factors. While it is generally not life-threatening, it can lead to physical discomfort and self-esteem issues. Treatment options include braces or, in more severe cases, surgical intervention to correct the deformity.
