They can be isolated findings or part of syndromic pathologies. They are typically seen on long bones, while their occurrence on flat bones is rare. The main concern after their identification is malignant transformation therefore size and cartilage thickness are monitored until the maturation of the skeleton and therefore seize of growth (unless malignant). This case report presents a 16 year old girl diagnosed with a benign isolated osteochondroma of the left scapula. X-Rays and MRI scans were used for diagnosis and for monitoring the progression for one year, while a CT scan aided planning for surgical excision for cosmetic purposes. The tumor was removed and histology confirmed its benign nature. Apart from cosmetic proposes and malignancy indications for excision of benign osteochondromas include pressure effect on surrounding tissue, pain and fracture of stalk. In our case the tumor had a typically benign appearance; nevertheless histological examination is always the gold standard for diagnosis. [ABSTRACT FROM AUTHOR]
