What is Poland syndrome?
Poland syndrome is a rare condition that is characterized by underdeveloped or missing muscles that can cause anomalies in the upper body. The most common trait is that part of the chest muscle, the pectoralis major, is absent. Other features may include changes in the arm and hand on the affected side.
What causes Poland syndrome?
The cause is not known. Poland syndrome may be recognized at birth, but sometimes the signs are mild, and it is not diagnosed until puberty. No genes have been associated with the condition. The cause is believed to be disruption of blood flow in the arteries beneath the collarbone of the embryo.
What are the signs of Poland syndrome?
The signs of Poland syndrome include absence of part or all of the pectoralis major muscle, short fingers, webbed fingers, length discrepancy in the arms, rib abnormalities, nipple abnormalities, breast abnormalities, and other findings.
What are Poland syndrome care options?
There is no cure for Poland syndrome. However, reconstructive surgery can be performed to improve many of the anatomic differences seen in this condition.
