Enchondroma of hand, juxtacortical lesion and multiple enchondromatosis may present with atypia and hypercellularity which are commonly found in malignant lesions.
UBCs, ABCs and
enchondromas can occur in either the metaphysis or diaphysis.
Small
enchondromas, non-ossifying fibromas, and bone infarcts do not require these studies.
The origins of osteochondromas and
enchondromas. a histopathologic study.
Also noted was a rhizomelic and mesomelic shortening of all extremities with palpable osseous deformities secondary to
enchondromas, especially of the shoulders, hands, and lower extremities.
desmoid tumors, leiomyomas, fibroadenomas, any collagen-producing tumor
Enchondroma and chondrosarcomas Malignant: Synovial sarcoma, high-grade sarcomas, undifferentiated sarcomas;GIST?
Maffucci syndrome is a rare, non-hereditary sporadic subtype characterized by hemangiomas in addition to multiple
enchondromas. Hemangiomas are benign vascular tumors that are also usually asymptomatic; they, too, require close monitoring due to the risk of malignant progression.
(1,2) The condition manifests as multiple, subperiostial, cartilaginous deposits (
enchondromas), most often located within the long and flat bones, such as the femur, tibia, and pelvis, as well as the small bones of the hands and feet.
Chondrosarcomas may arise de novo (primary), or superimposed (secondary) upon preexisting cartilaginous lesions, such as
enchondromas or osteochondromas.
Some lesions, such as solitary bone cysts (Figure 4),
enchondromas (Figure 5), EG and Ewing's sarcoma, tend to be centrally located.
Enchondromas are hyaline cartilage tumors in the medullary canal.
Enchondromas sometimes cause dyschondroplasia of the long bones during childhood.
