[Poland syndrome].

We present two patients with symptoms typical of Poland's Syndrome: unilateral hypoplasia of the pectoral muscle and dysplastic anomalies of the ipsilateral upper limb. Additionally skeletal and G.U. tract abnormalities can be found. One of our cases shows stenosis of the ureterovesical junction which led to hydronephrosis and dilation of the ureter; in the other case the ventral portions of the 3rd and 4th right ribs are missing.
