Abstract
INTRODUCTION: Giant cell tumour of bone is a rare entity in children and seldom involves the distal humerus, even in adult patients. We present a case of giant cell tumour in the distal humerus of a child CASE REPORT: A 12-year-old boy presented to our tertiary level tumour unit with progressive pain in his left elbow and was radiologically and histologically found to have a giant cell tumour of his left distal humerus. He was treated with extended curettage, cryotherapy and PMMA cement with the addition of a supportive postero-medial locking plate. There was no recurrence noted at one-year follow-up DISCUSSION: The literature is reviewed to determine the epidemiology of this tumour, the histological and radiological findings unique to the lesion and the current best practice of treatment CONCLUSION: A rare case of giant cell tumour in the distal humerus of a child is presented. Giant cell tumour of bone should be considered in the differential diagnosis of a lytic metaphyseal lesion if the growth plates are open

Summary
Giant cell tumour (GCT) is a primary benign bone tumour that is locally aggressive, rarely metastasises and seldom undergoes malignant transformation. It is diagnosed with combined radiological and histological assessment. The patient was admitted for local and systemic staging, which was followed by an incisional biopsy. Definitive surgery was performed seven days after the histological confirmation was obtained This was performed through a postero-medial approach based on the biopsy incision and consisted of curettage, extended with high-speed burring, and adjuvant cryotherapy with liquid nitrogen. Confirmatory histology from the definitive procedure confirmed the incisional biopsy results of a benign GCT. There were no clinical or radiological signs of recurrence (Figures 6 and 7)
