Osteochondroma (Subscribe)  

Dysplasia epiphysealis hemimelica (DEH), or Trevor disease, is a rare developmental disorder affecting the epiphyses in young children. The first report of DEH in the literature was by Mouchet and Belt in 1926, who described the condition as a tarsal bone disorder and used the term tarsomegalie. In 1950, Trevor...

Osteochondroma and Osteochondromatosis - An osteochondroma is a cartilage covered bony excrescence (exostosis) that arises from a surface of a bone.

2 synonyms or equivalents were found. Osteochondroma aka/or Osteocartilaginous exostosis "A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is...

Osteochondroma / Osteocartilaginous Exostosis Discussion: - a developmental dysplasia of peripheral growth plate which forms a cartilage capped projection of bone found near metaphyses of long bones; - peripheral chondroblast grows outward from the metaphysis, acting as an ectopic...

Osteochondromas are cartilage-covered, histologically normal bony projections (exostoses) on the external surface of a bone in the vicinity of growth plates. They are the most common benign bone lesions and present during late childhood and adolescence. Although any bone with enchondral ossification may be involved, the femur, the proximal tibia,...

Exostoses

This article describes a case of a 11-year-old boy with an osteochondroma of the peroneal head causing peroneal nerve palsy. Physical examination disclosed large exostoses palpated at the right fibular head. Neurological examination revealed paresis of the tibialis anterior, lateral peroneal, and extensor digitorum muscles with a muscle strength grade...

Osteochondroma is the most common benign bone tumor. These tumors are often diagnosed as an incidental finding. They account for approximately 35% of benign bone tumors and 9% of all bone tumors. Most are asymptomatic, but they can cause mechanical symptoms depending on their location and size. As benign lesions, they...
