Osteochondroma is a cartilage-covered bony excrescence that arises from the surface of a bone. It is the most common benign bone tumor in the scapula and can also present as multiple masses in multiple hereditary exostosis. A solitary scapular lesion might lead to "snapping scapula" syndrome, which is characterized by a sometimes audible but usually palpable grinding sensation experienced with scapular abduction. Snapping scapula is usually painless without specific symptoms; however, discomfort may result from the mechanical effects of a ventral scapular mass projecting onto a normally smooth, gliding scapulothoracic joint. Furthermore, malignant transformation of the cartilaginous cap, by virtue of the increased mass, may precipitate symptoms. The visual deformities and interference with major joint function are the most frequent musculoskeletal complaints related by patients. Indications for operative intervention include painful mechanical dysfunction unresponsive to conservative measures and sarcomatous change. Ventral scapular osteochondromas have been reported to cause scapular asymmetry and should be ruled out as part of a differential diagnosis to a "winged" scapula. A solitary osteochondroma can be excised either by arthroscopic or by open means, with the size of the lesion dictating precise management. Scapular osteochondromas usually are detected early during maturation due to mechanical symptoms or gross deformity. Unfortunately, most require surgical excision. Most surgical excisions have been reported in adolescents and young adults. We report an unusual case of osteochondroma from the ventral surface of the scapula in 56-year-old woman who had experienced delayed onset mechanical symptoms which required surgical excision.
