1.Diagnosis and treatment of patellar chondroblastoma.
China Journal of Orthopaedics and Traumatology 2013;26(12):1059-1062
Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.

The Journal of the Korean Orthopaedic Association 1969;4(2):35-38
A benign chondroblastoma of bone which involved the proximal end of the right tibia of a 14 year old girl was presented. Clinical symptoms, signs, roentgenographic findings, and bone biopsy led to the diagnosis. The lytic lesion of bone, which was 4cm×3cm×2.5cm in size, was curetted and autogenous bone graft was done. Most of the lesion was composed of a dark bluegray substance, which was either friable or even hemorrhagic, and the other areas were more grayish, gritty and flecked with yellowish calcified material. The postoperative course has been satisfactory, showing no recurrence for a period of 10 months after surgery.

Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6 years). All cases involved the temporal bone. Three involved the left side and two the right. Chief complaints were long-standing localized pain and hearing difficulty. A sharply demarcated lobulated mass was the main radiological finding. Microscopic findings were those of chondroblastoma of usual locations. Two cases showed aneurysmal bone cyst-like areas. Immunohistochemical studies for CD34, CD99, S-100 protein and cytokeratin were performed. Tumor cells were diffusely positive for S-100 protein in three cases and weakly positive for cytokeratin in one case. CD34 and CD99 were negative in all cases. In summary, chondroblastoma of the temporal bone is rare and occurs in older age group than reported cases of chondroblastoma of the usual location in the literature.

Aneurysmal bone cyst is relatively rare, benign tumor in the adolescent. An aneurymal bone cyst in the skull base is much more rare. This lesion is frequently accompanied with other conditions such as fibrous dysplasia, osteosarcoma, and chondroblastoma. The differential diagnosis is important;however it is difficult to make a correct diagnosis. The diagnosis is usually made from CT and pathological findings such as multi-lobulated, thin-walled cyst filled with blood. The treatment of choice is complete excision, if possible. We experienced a case of aneurysmal bone cyst arising from petrous bone, which was treated with transtemporal approach with partial excision. The patient remains free of symptom for 24 months with some tumor remaining in the clival area.

6.A Case of Benign Chondroblastoma of the Temporal Bone.
Journal of Korean Neurosurgical Society 1982;11(3):327-332
A 39 year-old male with swelling of the left temporal region, the left facial numbness, visual disturbance and slurred speech had been treated. Pain skull film showed an osteolytic bony defect in the left temporal squama with sclerotic margin. Left carotid angiogram showed a mass effect on the subtemporal region. CT scan revealed a well demarcated homogenous increased density of a snowman appearance in the left temporoparietal region. On operation, the temporal extradural highly vascularized mass was totally removed piecemeal, and another 6x5x5 cm of grayish brown rubbery-hard mass which located in the temporal lobe parenchyme was removed en bloc. The mass seemed to be extended from the extradural region. The histological diagnosis was a benign chondroblastoma. The patient was discharged without any evidence of neurological deficit.

Chondroblastoma is a rare primary bone tumor, The radiologic findings are so similar as giant cell tumor, osteolytic osteogenic sarcoma, enchondroma, bone tuberculosis, etc, but the treatment and prognosis are quite different, the differential diagnosis is mandatory. We experienced unusual huge giant chondroblastoma (10X7X5cm in size) occured in distal femur.

A 25 year-old man complained of pain at the distal interphalangeal joint of the middle finger for 3 months. The radiographs revealed an unicondylar osteolytic lesion at the head of middle phalanx. Enchondroma was initially suspected and curettage was performed, and final diagnosis was chondroblastoma. The size of the lesion increased and multiple septation developed at 9 months follow up. Curettage and bone graft was performed. Radiologic improvement was observed at 1 year after operation. Chondroblastoma developing at the phalanx is first report in our country, and this report can serve as a reminder at the diagnosis of osteolytic lesion in hand.

PURPOSE: To assess the MR imaging features in differentiating a chondroblastoma (CB) from a giant cell tumor (GCT), with an emphasis on the accompanying peritumoral bone marrow edema. MATERIALS AND METHODS: MR imaging findings in 20 patients with CB were compared with the imaging features of 22 patients with GCT. The location of the lesion, signal intensity, adjacent cortical change, degree of accompanying bone marrow edema, synovitis in the adjacent joint and cystic change were analyzed. The findings of CB and GCT were examined statistically with use of Fisher's exact test. RESULTS: The incidence ratios of MR imaging findings were as follows (CB:GCT). Metaphyseal dominant involvement (2:21), partial cortical disruption (2:14), extensive bone marrow edema surrounding the tumor (14:0) and synovitis in the adjacent joint (11:2) were statistically different in incidence between CB and GCT (p < 0.01). The inhomogeneous signal intensity (17:17) and cystic change (10:15) were not different in incidence between a CB and a GCT. CONCLUSION: The presence of metaphyseal dominant involvement and cortical disruption favors a diagnosis of a GCT rather than a CB. In contrast, extensive bone marrow edema surrounding the tumor and synovitis in the adjacent joint are highly indicative of a CB.
