ABSTRACT

Chondroblastoma is a chondroid bone tumor that frequently affects long bone epiphysis, malignancy occurs infrequently. It can alter the morphology of the joint, and appears in the second decade of life before ossification of the physes. Chondroblastoma accounts for 10% of chondroid tumors, on X-rays, it appears as a small radiolucent lesion, well defined with lytic activity and in case of aggressiveness, the lesion can extend to metaphyses. According to Enneking’s classification, chondroblastoma is benign injury, with capacity of physes destruction. Prognosis improves when treatment is carried out in a timely manner. It appears clinically in the shoulder, with pain, range of motion limitation, and poor answer to NSAID’s and/or physical therapy. We present a 17 year old male, with a two-year history of nightly pain of the shoulder, with poor response to NSAID’s therapy, and sever ROM limitation. On plain X-rays a lytic expansive lesion involving proximal humeral epiphysis was found. We performed wide curettage aided by fluoroscopy and 60 grams of lyophilized bone graft were used. Results: At 2-year follow-up full integration of bone graft, complete remission of symptoms and painless ROM of the shoulder were achieved.
