A 6-month-old, intact male Great Pyrenees (35 kg) was referred with 2 weeks continuous left forelimb lameness to the Chonbuk Animal Medical Center, College of Veterinary medicine, Chonbuk National University. The lameness became worse three days before being referred to the hospital. Upon the physical examination, the patient had pain when the left shoulder joint was palpated, and the lameness was visible in the left forelimb during ambulation on gait examination. There were no remarkable findings on radiological and neurological examination. Osteochondritis dissecans (OCD) was suspected based on medical history and gait tests. As a definitive diagnosis could not be made, exploratory arthroscopic surgery was performed to examine the inside of the shoulder joint. During the operation, mild bicipital tenosynovitis, synovitis and OCD which was located on the caudal medial area of humeral head were revealed. Arthroscopic procedures were used for the treating OCD, including the removal of the OCD flap and debriding of the subchondral defect until hemorrhaging by use of an electrical burr. The patient was discharged a day after surgery. After 2 weeks, the patient again presented at the hospital due to complications, including inflammation of the surgical lesion because of licking and seroma within the subcutaneous tissue. Antibiotics were administered and an aseptic bandage was applied. And simple surgical operations were performed for the removal of the cyst and seroma. Eleven weeks following arthroscopy, the lameness was completely resolved. Arthroscopy has the advantage of allowing gross examination inside the joint capsule. Due to this advantage, arthroscopy is one of the best advanced options for diagnosis in dogs with undiagnosed joint pain.

Leiomyosarcoma is an uncommon soft tissue sarcoma of mesenchymal cell origin, which shows smooth muscle differentiation. Leiomyosarcoma is seldom found in the pediatric population, and accounts for fewer than 2% of all soft tissue sarcomas. Leiomyosarcoma of the chest wall is extremely rare in children. We report here a case of an 8-year-old boy with a primary leiomyosarcoma that was incidentally found as a rib mass. The patient underwent a complete resection for a suspected osteochondroma diagnosed by a three-dimensional chest computed tomography examination. Pathological findings of the mass revealed intersecting fascicles of spindle cells showing cigar-shaped nuclei, inconspicuous nuclear pleomorphism and occasional mitotic figures in the background of a suspected osteochondroma of the rib. This report documents the first description of a leiomyosarcoma possibly arising in an osteochondroma of the rib in a child.

Osteochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and the proximal metaphysis of the tibia, however, is occurred rarely on the facial skeleton. Development of the tumor is most frequently seen in the second or third decades of life. Typically, it arises directly from the cortex of the underlying bone, without any intervening zone of abnormal osseous tissue, and is covered by a cap composed of cartilage undergoing calcification. In case of osteochondroma of the mandibular condyle, its clinical features are occulusal change, facial asymmetry, headache, pain and click on temporomandibular joint, mouth opening limitation, and jaw deviation to involved site. This is a case report of a 13-year old woman who had mouth opening limitation and severe temporomandibular joint pain. We obtained successful results with surgical removal of the osteochondroma on the mandibular condyle.

Osteochondroma is the one of the most benign tumors of the axial skeleton, but is rarely found in the facial bones. Typical facial features of condylar osteochondroma include striking facial asymmetry, malocclusion with openbite on the affected side, and prognathic deviation of the chin and crossbite to the contralateral side. In this case, twenty four year-old female showed facial asymmetry, chin deviation, openbite on the affected side but have no symptoms of pain or dysfunction. Concomitantly she had maxillary occlusal cant and hemimandibular hypertrophy. Panoramic radiograph showed radiopaque mass on right mandibular condyle extended along the lateral pterygoid muscle. Computed tomogram demonstrated enlarged condylar head and bony spur on posteromedial side of condyle and 99Tc bone scintigraphy showed a focal hot image. These findings were correspond with osteochondroma. The lesion was treated with condylectomy and residual facial asymmetry was corrected with 2-jaw orthognathic surgery. Herein, we report a case of osteochondroma of the mandibular condyle and accompanying facial asymmetry.

Benign and malignant tumors are found in the foot, although the incidence is low. The most common bone tumor in the foot is osteochondroma, which is thought to develop in bones that form through the process of enchondral ossification. In particularly, osteochondromas in the foot mostly occur in metatarsal bones and phalanges. It is seldom found in talus. It is usually confused with osteophyte or enthesis. We report an osteochondroma case confirmed by roentgenographical and pathological investigation, after removing the masses form bilateral tali of a 19-year-old male patient presented with bilateral ankle joint pain for three years.

Spontaneous hemothorax vary in cause and are rare for hemothorax induced osteochondroma. Sometimes hemothroax is reported due to osteochondroma induced injury of diaphragm, lung, pericardium, heart, or pleura. We report a patient with diaphragm laceration due to osteochondroma.

Osteochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and proximal metaphysis of the tibia. However, it occurred rarely on the facial skeleton. The coronoid and condylar processes have been considered to be the most common sites of occurrence for osteochondroma of the facial skeleton. The first treatment of osteochondroma is condylectomy, whereas extirpation was done by excision with condyle salvage. Condylectomy presents decrease of vertical dimension, jaw deviation, malocclusion. So, reconstruction is need. Methods of reconstruction are as follows: no reconstruction, condyloplasty, discectomy, costochondral graft, discplication or coronoidectomy, eminoplasty, alloplastic spacer placement, Le Fort I level maxillary osteotomy, extraoral and intraoral vertical ramus osteotomy. This is a case report of a 28-year old woman who had facial asymmetry, malocclusion and temporomandibular joint pain. We obtained moderate functional and cosmetic results with surgical removal of the osteochondroma by condylectomy and concomitant reconstruction of condyle by vertical ramus osteotomy with sliding technique.

Osteochondroma is one of the most common bone tumors. It can occur anywhere, although it is most frequent mainly around the metaphysis of long bones. Prediction sites are distal femur, proximal humerus, proximal tibia, and so on. However, osteochondroma in sesamoid is very rare. Herein, we report a case of a 56-year-old woman with symptomatic extra-articular osteochondroma in hallucal sesamoid with a brief literature review.

The osteochondroma, also known as osteocartilaginous exostosis, is one of the most common benign tumors of the axial skeleton. These tumours rarely affect the facial skeleton and a true osteochondroma of the mandibular condyle is a very uncommon entity. The tumors are usually slow growing, and symptoms develop over a long time. The most common presentation of the condylar osteochondroma consists of a changing occlusion, the development of facial asymmetry, and a posterior open bite on the affected side. In this case, we treated an osteochondroma of Lt. mandibular condyle through excision of the lesion via the temporal approach to the temporomandibular joint.

Osteochondroma is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones and extremely rare in mandibular condyle. The clinical signs and symptoms of osteochondroma of mandibular condyle may resemble those seen in patients with temporomandibular joint (TMJ) dysfunction. Condylectomy have been the first choice for treatment of osteochondroma, but it may be with some complicaitons, loss of condylar vertical height, etc. A 57 years old female patient who had an osteochondroma on left mandibular condyle visited to our clinic. We did surgically remove the mass with favorable result, so we present the case with review of literatures.
