Poland’s Syndrome: a Cadaver Case Study

We observed a rare variant case of Poland syndrome in a 55-year-old male cadaver in gross anatomy dissection room at department of Anatomy school of Medicine. His past and family history was not remarkable. The outward appearance of anterior thoracic wall, deltoid and shoulder regions revealed obvious abnormalities. Upon dissection, the following features were observed: (1) On the right side, the pectoralis major and minor were completely absent and deltoid muscle was hypotrophied therefore, the deltoid region in the right side was seen weaker in comparison with the opposite side. (2) A thick fatty layer about 3 cm was replaced instead of both the pectoralis major and minor muscles. (3) The distance between the neck and the upper part of deltoid region was seemed shorter on affected side (right side) in other words, the right clavicle bone was seemed a little shorter than the left clavicle bone. (4) The fingers of the right hand show webbing. Due to the absence of the pectoralis major and minor muscle that were accompanied with webbing and shortening in fingers of the hand of same side, the presented case was a rare variant of the Poland syndrome.
