What Is Poland Syndrome?
5. Occurrence
Poland syndrome is considered to be a rare disorder. It is thought that for every 30,000 to 80,000 babies born, one will be born with the condition. It is three times more likely to occur in boys than girls, and three times more likely to occur on the right side of the body than on the left.
For people whose pectoral muscles and arms have been underdeveloped or malformed since birth, Poland syndrome is the most likely diagnosis. However, many cases may go undiagnosed, especially when symptoms are mild and don’t involve the hands. Women especially may feel embarrassed to have a doctor examine their breasts and consequently not seek treatment.
