Chondrosarcoma of small bones of the hand arising from enchondroma
Dynamic contrast-enhanced MR imaging for differentiation between enchondroma
versus chondrosarcoma in the appendicular skeleton: differentiating features.
The differential diagnosis of hereditary multiple exostoses includes the enchondromatosis, which are a heterogeneous group of syndromes that present with multiple enchondromas
associated with pathological fractures, pseudarthrosis, limb shortening, malignant transformation risk, and scoliosis.
MRI visualized one hydrocele, one osteoma of the left femur, one enchondroma
of the pubic bone, and one dilated left ureter without clinical symptoms or therapeutic relevance.
A subsequent biopsy produced neoplastic tissue consistent with an enchondroma
11] Other benign tumours were chondroblastoma, enchondroma
, osteoma and osteochondroma.
The left small finger mass was reported as an enchondroma
or low grade chondrosarcoma (Fig 2).
We present the case of a patient with generalized enchondromatosis who developed a large enchondroma
of the clivus, and we discuss the clinical presentation and potential treatments for this entity.
Differential diagnoses of IOG cysts include: aneurysmal bone cyst, osteoblastoma, giant cell tumour, fibrous dysplasia, chondromyxoid fibroma, osteiod osteoma, rheumatoid arthritis, simple bone cyst, enchondroma
, chondroblastoma, and subchondaral bone cyst.
Four patients (12%) did not have follow-up treatment at our institution (1 with enchondroma
, 2 with osteosarcoma, and 1 with chondroblastoma) to compare the diagnostic accuracy of the FNACBP procedure.

Low-grade chondrosarcoma can be difficult, if not impossible, to differentiate from an enchondroma
, which is the primary alternative consideration in the differential diagnosis.
On the other hand, diagnoses specific to older patients include metastasis, multiple myeloma, enchondroma
, and subchondral cysts.
