Poland Syndrome (Funnel Chest)

peex_13a_n.jpg: In this 4.9-year-old girl with funnel chest an aplasia of the left major pectoralis muscle and a shorter left arm is obvious. peex_13b_n.jpg: Not only the shorter left arm is impressive, but the smaller left hand, too, in comparison to the contralateral side. The diagnosis is Poland syndrome, which may include hypo- or aplasia of the sternocostal part of the major pectoralis muscle, malformations of the same arm and hand, of the mammary gland, and the chest wall.
