Poland Syndrome

Poland syndrome is characterized by an underdeveloped or absent chest muscle on one side of the body, absence of the breastbone portion (sternal) of the chest muscle, and webbing of the fingers of the hand on the same side. The cause of Poland syndrome is not known. This syndrome is nearly always sporadic. It tends to occur on the right side and is more common in boys than girls. Treatment typically involves surgical correction of the chest wall deformities.
