Complete local tumor control after curettage of chondroblastoma–a retrospective analysis

“…Overall, our results correspond to published data of the literature [7]: showing a clear male predominance (1:2.7), presenting with pain in most of the patients [2,3,8,12,19]. The most frequent tumor site was the femur, followed by the humerus and the tibia affecting more frequently the proximal meta-epiphyseal region [6].…”

“…The additional use of phenol in cases of concomitant aneurysmal bone cysts is helpful in the avoidance of recurrence, even though the significance of secondary cysts also lacks unanimous answer. However, in a recent multi-centre study, Xu et al [9,12] showed curettage and bone grafting to provide favorable local control and satisfactory functional outcome for patients with chondroblastoma.…”

“…However, all of these patients presented free of local recurrence and without malignant transformation at their latest follow-up visit. Diagnosis of the lesion was based on recognized radiological and histological criteria [5,12] evaluated by the same institutions and a specialized musculoskeletal pathologists and orthopedic surgeons over the whole study period. Prior to this investigation the corresponding Institutional Review Board has approved the study (EK-1736/2013).…”

What Happens to the Articular Surface After Curettage for Epiphyseal Chondroblastoma? A Report on Functional Results, Arthritis, and Arthroplasty

“…Aggressive curettage remains the mainstay of treatment for chondroblastoma of bone, because it is associated with a low likelihood of metastases and local recurrences [24,26]. However, considering that this epiphyseal tumor affects primarily children and young adults, the question arises whether this treatment approach also results in durable preservation of the patient's native articular surface over the years after the initial treatment.…”

Chondroblastoma of extra‐craniofacial bones: Clinicopathological analyses of 103 cases

“…The incidence is about 1.45% of all primary bone tumors . CB usually affects the epiphyses of long bones, in young patients . Histologically, CB usually features diffuse proliferation of mononuclear round cells, often with cleaved nuclei, and pink “immature” cartilage islands.…”
