Pigeon chest, clinically known as pectus carinatum, is a chest wall deformity where the breastbone protrudes outward.
Understanding Pectus Carinatum (Pigeon Chest)
Pectus carinatum (PC), or pigeon chest, occurs when there is an overgrowth of the cartilage connecting the ribs to the sternum (breastbone). This overgrowth causes the middle of the chest to stick out. Essentially, instead of the chest being relatively flat, it appears to be pushed forward, resembling the chest of a pigeon.
Key Characteristics of Pigeon Chest:
- Protrusion: The sternum and ribs jut outwards.
- Cartilage Overgrowth: Excessive growth of the cartilage is the primary cause.
- Appearance: The chest looks like it's projecting forward, creating a visible bump.
When Does Pigeon Chest Develop?
According to the reference, PC is most common in adolescent males, with 90 percent of cases diagnosed after children reach 11 years of age. This means it often becomes apparent during puberty.
Differences between Pectus Carinatum and Pectus Excavatum
It's important to note the difference between pectus carinatum and pectus excavatum:
| Condition | Description | Chest Appearance |
|---|---|---|
| Pectus Carinatum | Overgrowth of cartilage causing the sternum to protrude outward. | Chest sticks outward |
| Pectus Excavatum | A depression or inward concavity of the sternum. | Chest caves inward |
Why is it Important to understand?
- Diagnosis: Recognizing the condition is the first step towards proper management.
- Treatment: While not always necessary, there are treatment options available for more severe cases.
- Psychological Impact: Addressing the condition can improve self-esteem in affected individuals.
In summary, pigeon chest (pectus carinatum) is a visible chest deformity characterized by the outward projection of the breastbone due to cartilage overgrowth, most commonly affecting adolescent males after the age of 11.
