WHAT IS POLAND’S SYNDROME?
Poland’s syndrome consists of hypoplasia or complete absence of the breast, costal cartilage and rib defects, hypoplasia of the subcutaneous tissues of the chest wall, and brachysyndactyly.

The cause of Poland syndrome is unknown. However, an interruption of the embryonic blood supply to the arteries that lie under the collarbone (subclavian arteries) at about the 46th day of embryonic development is the prevailing theory.

There is absence of the sternal head of the pectoralis major although the clavicular head is present. (Image Courtesy of Dr. Hollis H.
