Osteochondroma is the most common bone tumor representing 20%-50% of all benign bone tumors and 10%-15% of all bone tumors. Osteochondroma has similar radiological appearance in both solitary and multiple forms; the latter is an autosomal dominant disorder termed hereditary multiple exostoses. Associated complications of osteochondroma include deformity, fracture, neurovascular compromise, bursa formation, and malignant transformation. Read More

Rapidly Growing Solitary Osteochondroma in the Adult Finger A Case Report.

Bull Hosp Jt Dis (2013) 2022 Jun;80(2):171-174

Osteochondromas are common benign bone tumors that are most commonly found in children and adolescents. They are usually slow-growing and located at the metaphysis of the long bones. When present in adults in atypical locations or with concerning features, such as thickened cartilage cap and rapid growth, osteochondromas warrant imaging to assess the risk of malignant transformation into chondrosar- coma and may require surgical excision.

Update on the imaging features of the enchondromatosis syndromes.

Skeletal Radiol 2022 Apr 24;51(4):747-762. Epub 2021 Jul 24.

Imaging Department, Royal National Orthopaedic Hospital, Stanmore, UK.

Ollier disease and Maffucci syndrome are the commonest enchondromatosis subtypes, arising from non-hereditary mutations in the IDH1 and IDH2 genes, presenting in childhood and being characterised by multiple enchondromas. Maffucci syndrome also includes multiple soft tissue haemangiomas. Aside from developing bony masses, osseous deformity and pathological fracture, ~ 40% of these patients develop secondary central chondrosarcoma, and there is increased risk of non-skeletal malignancies such as gliomas and mesenchymal ovarian tumours.

Department of Radiology, Royal National Orthopaedic Hospital, Stanmore, UK.

Solitary osteochondromas are common, benign hyaline cartilage-capped exostoses that primarily arise from the metaphyses of long and flat bones. Diaphyseal aclasis is an autosomal dominant condition resulting from EXT1 or EXT2 gene mutations and is characterized by multifocal osteochondromas. These can result in a wide spectrum of complications, such as skeletal deformity, neurological and vascular complications, adventitial bursa formation, fracture, and rarely malignant transformation to peripheral chondrosarcoma.
