A fatal case of pure metaphyseal chondroblastoma

Abstract

The chondroblastoma (CB) is a rare cartilaginous tumour; it represents less than 1% of all bone tumours. It is mostly localised at the level of the epiphysis of long bones. We report a fatal case of pure metaphyseal CB of the tibia in a 9-year-old boy whose pulmonary metastases developed soon after operative therapy of the primary tumour.

Management of Chondroblastoma of the Femoral Head by Controlled Hip Dislocation Technique and Use of Allograft: Case Report

“…18] as seen in our patient (Figure 1). Symptoms include pain (depending on the anatomical location), antalgic gait (when located in lower extremities) specially in articular locations [3,6,8,13,17,22].…”

“…Usually, poligonal chondroblast like cells are present, they are well circumscribed in the surface and posses cleft nuclei. At the same time, foci of cartilaginous matrix are present (pink chondroid) with focal calcifications that give the char-bone tumors; 9% of benign bone tumors), with variable local aggressivity depending on its anatomic location [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]20,21]. It presents predominantly in male patients with a 2:1 relationship [1,2,4,16], as well as in long bones, specially in the humerus and the femur [4,5].…”

“…Nowadays there is no standard procedure for surgical management of EC [14,17,23], specially when located in the femoral head. Literature has described EC since 1927 and frequently states that complete resection of it through curettage should be a standard of care, including multiple options for covering the remaining defect, mainly by means of structural allograft [1][2][3][4][5][6][8][9][10][11][12][13][14]16,17,23,24].…”

“…EC is described as a benign infrequent tumor with local aggressive capacity [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], being the femoral head one of the most challenging locations for surgical management [2,10,11]. The clinical and radiological diagnosis reveals distinctive characteristics that allow the identification of the lesions and so its management [4,11,17]. Great controversy exists regarding the best surgical management since, although it has been established that complete lesion resection is a standard, the use of adjuvants and allografts has not been globally accepted [4,8,9,11,12].…”

Synchronous chondroblastomas in the knee joint: A case report

“…CB can occur even in the distal phalanx of a finger [2] . CB rarely metastasizes to the lungs [3] . A histologically proven case of CB with multiple distant soft tissue metastases has been reported as a rare finding [4] .…”
