Benign chondroid neoplasms like enchondroma
and osteochondromas are common bone tumours affecting hands and feet.

In addition to Sturge-Weber syndrome, this category includes such rare entities as Klippel-Trenaunay syndrome (CM + VM +/- LM + limb overgrowth), Proteus syndrome (CM, VM and/or LM + asymmetric somatic overgrowth) and Maffucci syndrome (VM +/- spindle cell hemangioma + enchondroma
Pathological types of tumors: nine cases of aneurysmal bone cyst, 11 cases of simple bone cyst, eight cases of bone fibrous dysplasia, nine cases of enchondroma
, three cases of non-ossifying fibroma and two cases of eosinophilic granuloma.
Among the seven articles in the first issue were: "Ossifying Enchondroma
of the Head of the Humerus" by Philip Barack, "Tuberculosis of the Ischial Tuberosity: Partial Resection of the Ischium" by Henry Milch, "Xanthogranuloma of the Knee Joint" by Milton Friedman and Arthur Ginzler, and "Osteochondritis Dissecans of the Femoral Head" by Aaron M.
Benign rib lesions originating from bone or cartilage include fibrous dysplasia, enchondroma
, aneurismal bone cyst, and eosinophilic granuloma.

SCH has been diagnosed as various entities including mucocele, hemangioma, pyogenic granuloma, synovial sarcoma, and enchondroma
(Table 1) [1-12].
Similar to enchondroma
it is a lesion arising in medullary cavity with irregular matrix calcification, but chondrosarcomas have a more aggressive appearance with bone destruction, cortical erosion, periosteal reaction and rarely a soft tissue mass.
The differential diagnosis of fibrous dysplasia includes lesions like Paget's disease, Non ossifying fibroma, Simple bone cyst, Enchondroma
, Adamantinoma, Aneurysmal bone cyst, Osteofibrous dysplasia, Diffuse sclerosing osteomyelitis and Giant cell tumour.
