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.
, non-ossifying fibromas, and bone infarcts do not require these studies.

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

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
Some lesions, such as solitary bone cysts (Figure 4), enchondromas
(Figure 5), EG and Ewing's sarcoma, tend to be centrally located.
