The hereditary multiple osteochondromatosis is a hereditary disorder characterized by gradual development of numerous osteocartilagenous masses from the metaphyseal region of long bones. The abnormality is transmitted as an autosomal dominant trait and its etiology is unknown but many theories of pathogenesis have been advanced. Four members of a family with hereditary multiple osteochondromatosis who are much shorter in height are presented with a brief review of literatures.

The so-called "Hereditary Multiple Exostoses" disease is characterized by hard, irregular prominences appearing in the metaphyseal region of the bones. Though transmitted as an autosomal dominant trait, skipped generation are reported and presumably represent spontaneous mutations. We experienced one case of hereditary multiple exostoses of 15 years old male patient, whose father and one brother were also affected. A brief review of related literature is also presented.

Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. This is a case report of a 49-year-old woman with an osteochondroma mimicking a mediastinal mass in hereditary multiple exostoses. The chest X-ray and computed tomography (CT) scans revealed the bony density feature of the mass. Surgical excision confirmed that the lesion was an osteochondroma.

Multiple osteochondromatosis is a hereditary disorder affecting the endochondral skeleton during period of growth. We have studied a family which have multiple osteochondromatosis clinically and radiologically. In this family, eight of ten members could traceable, have the lesions of multiple osteochondromatosis. The most common site of the lesions was in femur, and the next common site was in tibia, especially, near the knee joint.

Osteochondroma, the most frequent benign bone tumor, is composed of trabecular bone covered with a hyaline cartilage cap. It is well known that multiple osteochondromatosis may undergo malignant change. Such sarcomatous change usually present with the form of chondrosarcoma, and transformation to other malignancy is extremely rare. This report describes one case of osteosarcoma arising in patients who had multiple osteochondromatosis, and includes brief review of the literatures.

PURPOSE: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. MATERIALS AND METHODS: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (> or =3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. RESULTS: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was 10.7degrees, 13.8degrees, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. CONCLUSION: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.
