Enchondromas are benign chondrogenic tumors composed of hyaline cartilage that typically occur in medullary cavity of the diaphysis or metaphysis, most commonly in the hands. Patients typically present between the ages of 20-50 with an asymptomatic lesion, discovered incidentally on radiographs

Enchondroma is associated with heterozygous gain-of-function mutations in the genes for IDH1 or IDH2 (isocitrate dehydrogenase 1 (2q34) or 2 (15q26.1)). In 86% of enchondromas in enchondromatosis patients and in 52% of solitary enchondromas mutations in these genes have been found, as described above
Microscopically, an enchondroma is composed of islands of intramedullary hyaline cartilage surrounded by marrow fat, and a chondrosarcoma a diffuse cartilaginous replacement (invasion) of the marrow which leads to complete 'trapping' of host lamellar bone trabeculae. The marrow around islands of cartilage should be detectable. Cartilage-forming tumors as a group are the most common primary bone tumors; this is largely due to the common occurrence of asymptomatic benign lesions such as osteochondroma and enchondroma. The common feature of these tumors is the presence of chondrocytic cells and the formation of cartilaginous Among 356 Mayo Clinic bone tumors of the hands and feet, 143 (40.2%) were enchondroma but only 26 (7.3%) were chondrosarcoma. 1 This incidence of chondrosarcoma probably overestimates the true incidence, because patients with sarcoma are more likely to be seen at a large medical center

Enchondroma of the Hand: Evaluation and Management Enchondroma is the most frequently encountered tumour. Since the vast majority of enchondromas are asymptomatic, they are typically discovered as incidental findings or along with a pathologic fracture. In the CT-scan, the multilobular outlines of cartilaginous tissue may be recognised when the lesion is located in a fatty medullary cavity. Introduction. Osteochondroma is the most common benign neoplasm of bone, representing 10%-15% of all primary bone tumors and up to 50% of the benign lesions ().The prevalence of reported malignant transformation varies from less than 1% for solitary osteochondromas and 2%-5% for hereditary multiple exostosis (1,2).It can be inherently difficult to distinguish a low-grade chondrosarcoma.

Visual survey of surgical pathology with 11147 high-quality images of benign and malignant neoplasms & related entities The enchondroma also is derived from the actively proliferating cartilaginous tissue of growth plates. For unknown reasons certain groups of chondrocytes do not proceed to undergo hypertrophy and death. As a result, a column of uncalcified cartilage extends from the underside of the growth plate into the region in which all other cartilaginous. Enchondroma produces a localized, radiolucent defect with punctate or less frequently linear calcifications (see Figs. 6-2 to 6-5). Whether the lesion is sharply defined or has indefinite outlines within bone depends on the skeletal site. The degree of radiographic calcification can vary considerably Cartilage-forming tumors comprise one of the most common bone tumors, with enchondroma and osteochondroma encompassing the overwhelming majority of benign cartilaginous lesions and low-grade chondrosarcoma being the most common malignant cartilaginous tumor. 1 These tumors are characterized by the formation of a cartilaginous matrix and can sometimes display overlapping histologic features.

An enchondroma is a type of noncancerous bone tumor that begins in cartilage. An enchondroma most often affects the cartilage that lines the inside of the bones. It often affects the tiny long bones of the hands and feet. It may also affect other bones such as the femur (thighbone), humerus (upper arm bone), or tibia (one of the two lower leg bones) (enchondroma pathology outlines) The patients can be divided into two groups based on age: younger than 30 vs older than 30. The lesion borders can be described as a narrow zone of transition (the border is easy to define) vs a broad zone of transitio However, it is important to be aware that enchondroma cannot be reliably distinguished from chondrosarcoma by histology, and diagnosis depends on correlation of clinical, imaging, and pathology findings 9. Grossly, lesions are usually <3 cm, translucent, nodular, and are grossly greyish-blue..
Cartilage-Forming (Chondrogenic) Lesions. Diagnosis of a bone lesion as originating from cartilage is usually a simple task for the radiologist.

Chondroblastoma is a rare, benign, locally aggressive bone tumor that typically affects the epiphyses or apophyses of long bones. It is thought to arise from an outgrowth of immature cartilage cells (chondroblasts) from secondary ossification centers, originating from the epiphyseal plate or some remnant of it.. Chondroblastoma is very uncommon, accounting for only 1-2% of all bone tumors Chondro-osseous tumours occasionally cross the desk of the pathologist. They are grouped together as bone may develop from cartilage. Primary bone tumours are rare; the most common bone tumour is metastases. Bone tumours occasionally are lumped with soft tissue tumours. Soft tissue tumours are dealt with in the soft tissue lesions article Stanford Medicine » School of Medicine » Departments » Surgical Pathology Criteria » Fibroma of Tendon Sheath Navigation for This Section: Surgical Pathology Criteria Diagnostic Criteri Dedifferentiated chondrosarcoma consists of a low grade malignant hyaline cartilage tumor associated with a high-grade nonchondroid spindle sarcoma.

Radiographs provide information regarding the location, margins, matrix mineralization, periosteal reaction and aggressiveness of the lesion, and should be analyzed systematically [2, 3].This information, when interpreted together with the patient's clinical information such as age, lesion multiplicity and clinical presentation, provides a differential diagnosis of the lesion
Enchondromas are common intraosseous, usually benign cartilaginous tumors, that develop in close proximity to growth plate cartilage. When multiple enchondromas are present, the condition is called enchondromatosis also known as Ollier disease (WHO terminology). The estimated prevalence of Ollier disease is 1/100,000.

Chondromas account for 25 percent of all benign bone tumors. The exact cause is unknown. Enchondromas are the most common type of bone tumor found in the hand. Boys and girls are equally affected. They can occur at any age but usually enchondromas are not discovered until people are in their 30s or 40s Venous malformations are a type of vascular naevus or birthmark. They are due to malformed dilated veins and are non-cancerous. They appear as skin coloured, blue or purple swellings on any part of the body, and there are often prominent veins near the skin surface. Like capillary vascular malformations (port wine stains), venous malformations. Uterine carcinosarcomas (MMMT—malignant mixed Müllerian tumours) are highly aggressive, rare, biphasic tumours composed of epithelial and mesenchymal elements believed to arise from a monoclonal origin. While hysterectomy with bilateral salpingo-oophorectomy remains the mainstay treatment, high rates of recurrence and metastases suggest a need for lymphadenectomy and postoperative adjuvant. Bone is a dynamic organ of the endoskeleton, playing an important role in structural integrity, mineral reservoirs, blood production, coagulation, and immunity. Metabolic bone disease encompasses a broad spectrum of inherited and acquired disorders that disrupt the normal homeostasis of bone formation and resorption. For patients affected by these processes, radiologic imaging plays a central.

Bone tumors can affect any bone in the body and develop in any part of the bone—from the surface to the center of the bone, called the bone marrow. A growing bone tumor—even a benign tumor—destroys healthy tissue and weakens bone, making it more vulnerable to fracture. When a bone tumor is cancerous, it is either a primary.
