Abstract: Introduction: Giant cell tumour is a locally aggressive benign tumour of bone which is an unusual neoplasm that accounts 4% of all primary tumours of bone and about 10% of malignant primary bone tumours. GCTs are usually found in skeletally mature individuals. Peak of this is generally in 3rd decade. Tumors of the fibula comprised only 2.5% of primary bone lesions. Patients with aggressive benign tumors in the proximal fibula may require en bloc resection. Peroneal nerve function, knee stability, and recurrence are substantial concerns with these resections. We are reporting a case of Giant Cell Tumour of the proximal Fibula managed with curettage and excision with 5% phenol.
Case presentation: A 25-year-old female presented with complaints of pain and swelling and deformity below right knee since 1 year. Pain wast in right lower limb over fibular region which was insidious in onset Dull aching and progressive in nature with no radiation no diurnal variation 1 month after that she noticed swelling over proximal leg which was initially of pea size and gradually progressed to size of approx. 10x10 cm. There was no history of trauma. Surrounding skin appeared reddish brown. On palpation no local raise of temperature but local tenderness present. X rays and all blood investigations were done Histopathological report suggestive of giant cell tumour of bone benign type with plenty of giant cell, plenty of eosinophils and round oval stromal cells. Magnetic resonance imaging-large expansile lytic lesion noted in fibular head with lobulated margins and few internal cystic areas noted mass is displacing neurovascular bundles but no invasion favours possibility of ABC? GCT. After detail examinations and investigations and written informed consent patient was posted for surgery for excision of tumour. Spinal anaesthesia was given in supine position for surgery in all aseptic precautions and with haemostasis achieved, excision was done by the specimen was sent to histopathology for further examination. A thorough wash was given, and the defect was treated with 5% phenol. The tumour was sent for histopathological examination which confirmed the diagnosis of GCT. Histopathology of the tissue showed benign type of giant cell tumour.
Conclusion: Management of Giant cell tumor of fibula with Excision with curettage with, use of 5% phenol for GCT of bone achieved good functional outcome and a low recurrence rate.
