Hereditary multiple exostoses, an autosomal dominant condition, is a common benign tumor which is characterized by the development of multiple osteochondromas. Bilateral dorsal and ventral involvement of scapulae is extremely rare without any reported case in the literature. An 18-year-old girl was referred because of bilateral prominent scapulae and left-sided pain on shoulder girdle motion especially at more than 90° abduction and forward flexion. Radiograph evaluation showed multiple exostoses on ventral and dorsal surfaces of body of both scapulae; hence simple excision of the lesion was impossible. The patient was symptom-free about 18 months after partial scapulectomy of left side. Partial scapulectomy seems to be an effective treatment for the sandwiched scapula between dorsal and ventral benign tumors.
