Solitary osteochondroma of the scapula is rare. Because of the atypical location with unspecific shoulder pain, the diagnosis is often made late. We present a 35 year old patient with a solitary ostochondroma of the scapula with unspecific pain of the shoulder-neck region over about 4 years. In a thorax x-ray 2 years ago, a tumor like lesion was found. CT and MRI scan led to suspicion of a solitary osteochondroma of the scapula. Because of progressive thoracic pressure pain, a wide excision was made. The problems of diagnosis and therapy are presented and the literature is discussed.
