Pectus carinatum, also called pigeon chest or pidgon breast,[3] is a malformation of the chest characterized by a protrusion of the sternum and ribs. It is distinct from the related malformation pectus excavatum.

Pectus carinatum has an estimated prevalence of approximately 1 in 1,000 to 1,500 live births, though specific figures vary geographically. It is generally less common than pectus excavatum. The condition is more frequently observed in males, with a male-to-female ratio ranging from 4:1 to 7:1. It typically becomes more noticeable during periods of rapid growth, such as early adolescence.
