About one case of vertebral chondroblastoma.

The authors report the case of a 9-year-old child which suffered from a chondroblastoma of the cervical spine. He had clinical signs of superior mediastinum compression with inflammation of the respiratory upper air-way. Surgery was performed. Diagnosis was established by the pathologist. The recurrence one year later was treated again by surgery and also by radiotherapy. Another recurrence four years later was fatal. The difficulties of the diagnosis and the appearance of recurrences in some cases of chondroblastoma are reviewed in the literature.

[Grawitz's tumor with arterial hypertension in children. Apropos of a case]. / Tumeur de Grawitz avec hypertension artérielle chez l'enfant. A propos d'un cas.

A boy of two years has an hematuria which was first related with an hypertensive acute glomerulonephritis. However because of recurrency of the hematuria radiological investigations were performed and a solid tumor of the right kidney was discovered. The arterial hypertension regressed after the right nephrectomy. Pathology demonstrated a tumor of Grawitz which is rare in children and which is seldom associated with an arterial hypertension. We found only five similar cases in the literature. Arterial hypertension can be related either with a compression of the renal artery of with an inadequate secretion of renin by the tumor.

[Pleural involvement caused by contiguity or metastases in primary malignant bone tumors in children]. / Atteintes pleurales par contiguïté ou métastases dans les tumeurs osseuses malignes primitives de l'enfant.

Pleural location of primary osseous malignant tumors of children are infrequent. They may be secondary from a distant primary osteosarcoma. It is necessary to investigate them via conventional chest X-ray followed by a CT of the thorax. This examination shows the pleural lesion, its limits and calcifications. It must be remembered that this examination doesn't always confirm the pleural location of the lesions, the angle that they subtend is not an accurate guide. Comparison with clinical data is essential in difficult cases.

[Peritoneal metastasis of a pineoblastoma in a patient with a ventriculo-peritoneal shunt]. / Métastases péritonéales d'un pinéaloblastome chez une patiente porteuse d'une dérivation ventriculo-péritonéale.

A 12 years old child had an increase of intra cranial pressure secondary to a large pinealoblastoma. A ventriculo peritoneal shunt procedure was performed followed several days later by a partial resection of the pinealoblastoma. One year later, ultrasound and computed tomography examinations discovered a solid mass in the pelvis. At surgery it appeared to be a metastasis of the pinealoblastoma. It is a very seldom complication of the shunt and various mechanisms are discussed.

[Fragmented fracture due to fibrous lacunae of the lower femur. Apropos of a case]. / Fracture parcellaire sur lacunes fibreuses fémorales inférieures. A propos d'une observation.

The authors report a case of partial fracture of the border of a cortical defect of the distal femoral metaphysis after a mild trauma. Periostal apposition did evoke a tumor. Similar cases are very seldom in the literature.

[A case of vertebral chondroblastoma]. / A propos d'une observation de chondroblastome vertébral.

The authors have observed a case of cervical chondroblastoma in a child aged nine years. Clinically there was a mediastinal syndrome, with pulmonary tract infection. Resection was achieved in two stages. One year later a local recurrence was treated by a third resection, followed by radiotherapy. Three years later there was no sign of recurrence. A review of the literature summarises the difficulties of diagnosis.
