Osteochondroma of acromioclavicular joint.

Osteochondroma is the most common type of benign bone tumour. It is a benign chondrogenic lesion derived from aberrant cartilage from the perichondral ring, and it commonly presents in the proximal humerus, proximal femur and knee. Osteochondroma is usually solitary but can be multiple with patients with hereditary multiple exostoses.

Surgical treatment of rare case of scapula osteochondroma in a resource limited setting: A case report.

Introduction: Osteochondroma also known as exostosis is one of the most common benign bone tumours, and are characterized by bone protuberances surrounded by a cartilage layer. They generally affect the extremities of the long bones in an immature skeleton and deform them. They are easily diagnosed at the level of the appendicular skeleton.

[Chondrosarcoma arising in solitary osteochondroma: a case study].

Chondrosarcoma is a rare malignant bone tumor. It can arise de novo or secondary to a malignant transformation of a benign underlying cartilage tumor. Secondary chondrosarcoma arising from solitary benign osteochondroma is extremely rare and data show that the reported incidence of osteochondroma of the pelvis is very low.

Rare case of malignant transformation of a solitary spinal osteochondroma into recurrent metastatic chondrosarcoma.

Osteochondroma or osteocartilaginous exostosis is a commonly occurring primary tumor of the bone. Solitary spinal osteochondromas are, however, very rare, seen in only in 1-4% of all known cases and only few symptomatic cases have been reported in the literature so far. Further, while recurrence and malignant transformation are known to occur in osteochondroma, this is rare in the spine.

Arthroscopic resection of extra-articular knee osteochondroma: report of two cases.

Osteochondroma is the most common benign tumor of the growing bone, usually affecting the knee joint, located extra-articularly. Solitary intra-articular osteochondroma is very rare. In the current paper, two cases of solitary extra-articular knee osteochondromas adjacent to the capsule producing pain and restriction of knee motion are described.

Insights into the molecular regulatory network of pathomechanisms in osteochondroma.

Osteochondroma is a benign autosomal dominant hereditary disease characterized by abnormal proliferation of cartilage in the long bone. It is divided into solitary osteochondroma and hereditary multiple exostoses (HMEs). The exostosin-1 (EXT-1) and exostosin-2 (EXT-2) gene mutations are well-defined molecular mechanisms in the pathogenesis of HME.

Clavicular Osteochondroma: Extremely Rare Cause of Impingement Syndrome.

Introduction: Impingement syndrome is one of the most common pain disorders of the shoulder; it may be due by structural alteration of acromion, coracoacromial ligament, acromioclavicular joint, biceps tendon, or coracoid process; however, in rare cases, impingement syndrome may be due also by benign tumors such as osteochondroma.

Case Report: We presented a case of 27-year-old male with clavicular impingement syndrome secondary to osteochondroma. He received conservative treatment before the diagnosis of the osteochondroma.

Multiple Exostoses Syndrome and Basilar Artery Aneurysm: A Case Report.

Background: Hereditary multiple exostoses (HME) is an inherited genetic condition, characterized by the formation of multiple osteochondromas, developing throughout childhood and into puberty. Vascular complications associated with HME are uncommon.

Methods: A case of a patient with HME who was admitted to hospital with subarachnoid hemorrhage (SAH), as a result of acute rupture of a basilar tip aneurysm (BTA), will be presented.

An Unusual Presentation of Osteochondroma on the Dorsal Surface of the Scapula: A Review of Two Patients.

Introduction: Osteochondroma of the scapula is a rare tumour of the thorax. It constitutes 14.4% of all tumours of the scapula with the ventral surface being the most common site of presentation.

Regression of a solitary osteochondroma of the distal humerus in a toddler following trauma.

Osteochondromas are bone exostoses, with the vast majority extending from the metaphyseal region of long bones and are capped by cartilage. A review of the current literature reveals spontaneous regression of osteochondromas is a rarely documented event, with all but two of these recorded events resolving before skeletal maturity and within 6 years of identification. We present a case of trauma-induced resolution of a solitary osteochondroma after less than 3 months in a 15-month-old male, with a review of current literature.

Expansile radiolucent lesion of the Temporomandibular Joint-A diagnostic enigma.

Radiolucent lesions of Temporomandibular Joint (TMJ) represent a diagnostic challenge and a treatment conundrum. Biopsy of the lesions is technically difficult owing to their complex anatomy. The Differential Diagnosis (DD) includes a wide array of lesions including Simple Bone Cyst, Ameloblastoma, Central Giant Cell Granuloma, Hemangioma, Osteoblastoma, Osteochondroma, Chondroblastoma, Chondrosarcoma, Neurofibroma and metastatic malignant lesions though none has a specific predilection for TMJ.

Solitary osteochondroma in the body of the pubic bone: a cadaveric case report.

Osteochondromas develop as cartilaginous nodules in the periosteum of bones. They are the commonest benign tumors of the skeleton, generally observed in the long bones. Rarely, they are also found in the axial skeleton, flat bones of skull and facial bones.

Solitary Osteochondroma of the Spine-A Case Series: Review of Solitary Osteochondroma With Myelopathic Symptoms.

Study Design: Case series and literature review.

Objective: There is a growing body of literature supporting that osteochondroma of the spine may not be as rare as previously documented. The purpose of this study was to perform an updated review and present our experience with 4 cases of solitary osteochondroma of the spine, including surgical treatment and subsequent outcomes.

Solitary Osteochondroma of the Ventral Scapula Associated with Large Bursa Formation and Pseudowinging of the Scapula: A Case Report and Literature Review.

Osteochondroma (OC) is the most common benign bone tumor and may occur on any bone in which endochondral ossification develops. Although scapular OC accounts for less than 5% of the cases of solitary OC, OC is the most common lesion among the tumors and tumor-like lesions of the scapula. OC that develops near the medial scapular border easily causes friction with the ribcage; hence, almost half the number of cases of OC associated with marked bursa formation develops in the ventral scapula.

Solitary osteochondroma of the capitate, in a child.

Osteochondromas, are the most common tumors of the long bones in children. Osteochondromas are extremely rare in the carpal bones. They are diagnosed in adult life, in almost all cases in the literature.

Background: The geographic distribution of osteochondroma (OC) varies greatly around the world. There has been no recent report on OC in a large Chinese population. The aim of this study was to characterize OC by an epidemiological analysis of the clinical data from one medical institution in South China.

Diagnostic imaging of deep vein thrombosis secondary to osteochondroma formation.

Deep vein thrombosis (DVT) is a condition classically associated with blood stasis, hypercoagulability or injury to the vasculature. As blood stasis is usually associated with patient immobility, DVT occurrence in young active patients with no underlying haematological conditions is a rarity. An exostosis, also known as osteochondroma, is a cartilage capped lesion.
