Poland Syndrome

Poland syndrome is a congenital abnormality in which one side of the body, specifically the chest and hand, are not formed correctly. Besides from this physical defect, most children with Poland syndrome are perfectly healthy.


The incidence of Poland syndrome is 1 in 30,000 live births. Boys are affected 2-3 times more than girls. The disease seems to be sporadic, but there have been familial cases reported.

Signs and Symptoms

A child with Poland syndrome has the signs of the disorder at birth, but the diagnosis might be missed if those physical signs are mild. Children with this disorder have a malformed chest where the upper chest muscle (pectoralis major) and the nipple on one side is missing. The right chest is involved more often than the left chest, accounting for 75% of all reported cases. Children with Poland syndrome might have some abnormality of the hand (on the same side of the chest abnormality), where the fingers are short and/or fused together (symbrachydactyly). In some children, the rib cage on the same side might not form correctly. At puberty, children with this disorder will have very few or lack of axillary (arm pit) hair on the affected side. Some girls might have no breast or an underdeveloped breast on that side.

Possible Causes

The cause of Poland syndrome is said to be due to decreased blood flow to the chest, arm and hand region of the fetus in utero. It is hypothesized that the subclavian artery (the artery supplying blood to the areas mentioned above) is pinched or narrowed during the 6th week of fetal life, when the chest, arm and hand are developing. Not having enough blood may cause these regions to fail to develop fully.


The diagnosis can be made by physical exam or a CT scan of the chest. An X-ray of the chest and hand will also help the doctor learn more about the problems involving the rib cage and fingers of the child, if there are any.


Parents of children with Poland syndrome with hand problems often opt for hand surgery when the children are young. Most patients seek plastic or reconstructive surgery of their chest in their teens or adult years. A surgeon might use part of a chest/back muscle of the patient called lattisimus dorsi to replace the missing muscle in front. Sometimes a silicone implant can also be used. It is often suggested that girls with Poland syndrome wait until after breast development before they seek surgery.


Since Poland syndrome is mostly a cosmetic problem, the patients often lead very healthy lives. For those with severe problems, surgery is a very successful treatment and the patients normally can expect a full recovery.
