We report a case of a 28-year-old female who presents with painless, progressively increasing left upper chest swelling of 6 months duration. Examination revealed a 20 by 10 cm firm mass arising from the clavicle. She was investigated and a diagnosis established based on the histological report. The tumour was excised with a wide margin and reconstruction done with an autogenous fibula graft. Full functional ability was restored in limb with the radiological union. After 5 years of regular follow-up, there was no evidence of recurrence and shoulder function remained excellent. The successful management of this patient shows wide local excision and reconstruction as an excellent surgical option in treating giant cell tumour of the clavicle.

| Introduction|| |
Giant cell tumour is a rare benign but locally aggressive tumour  which occurs relatively commonly in bones of young adults. It was first reported by Cooper and Travers in 1881 and further characterised by Jaffe et al. in 1940. They are classified as 'intermediate locally aggressive rarely metastasising' tumours. Giant cell tumours account for over 20% of all benign bone tumours  and about 4%–9.5% of all primary bone tumours., The most common locations include the distal femur, proximal tibia and the distal radius. Less common sites include the sacrum, ilium, spine and the phalanges. Rarer sites include the clavicle, ribs, skull and sternum. The clavicle is a rare site for bone tumours of which giant cell tumour of the clavicle is quite uncommon among the tumours occurring in the clavicle.
| Case Report|| |
A 28-year-old female patient presented at the Lagos University Teaching Hospital, Lagos on August 2011 with 6 months history of a painless progressively increasing left upper chest swelling. The patient had not noticed any weakness or neurologic deficit in the left upper limb. On physical examination, there was a firm mass of about 20 by 10 cm in the left upper chest arising from the middle third of the left clavicle [Figure 1] and [Figure 2]. The skin over the swelling was normal in colour with no dilated veins. No pallor, lymphadenopathy or organomegaly was detected. Upper limb examination did not reveal any neurologic or vascular abnormality.

Chest radiograph showed a lytic lesion arising from the middle third of the left clavicle [Figure 3]. Computed tomographic scan of the chest demonstrated a multiseptated expansile lesion arising from the middle third of the clavicle [Figure 4]. The tumour was graded as Campanacci grade II. Incisional biopsy showed numerous multinucleated osteoclast-like giant cells disposed in a highly cellular stroma. The stromal cells in some areas were plump with round to oval nuclei identical to that seen in the giant cells and in other areas had spindle-shaped nuclei. The tumour was pathologically diagnosed as giant cell tumour of the clavicle and treatment was planned.
The patient had wide local excision of the lesion with a 3 cm margin medially and 3 cm margin laterally which included the clavicular end of the acromioclavicular joint [Figure 5]. The 14 cm defect created was bridged with a non-vascularised fibula graft harvested from the ipsilateral leg. This was fixed to the medial clavicle by plate and screws medially and laterally to the acromion with plates and screws [Figure 6] and [Figure 7]. Intraoperative blood loss was 300 ml. Post-operative state was uneventful. Physiotherapy exercises were commenced 4 days after surgery with a gradual increase in activity tolerance level until she achieved full range of movement of the left shoulder.

The patient was followed up for 5 years post-excision with no deterioration in functional status. Recent radiographs show graft union and consolidation with no evidence of tumour recurrence [Figure 8] or pulmonary metastasis. Shoulder function has remained excellent [Figure 9].
| Discussion|| |
The clavicle is a very rare site for bone tumours accounting for about 0.45%–1% of all tumours. Tumours of the clavicle are more likely to be malignant than benign.,, Giant cell tumour of the clavicle is quite rare with just a few number of case reports describing its occurrence.,,, The oncological properties of giant cell tumour of the clavicle closely resemble that of flat bones.
Clinical diagnosis of giant cell tumour of the clavicle is difficult to make, and histology is usually the gold standard. Notable differentials include tuberculous osteomyelitis, 'brown tumour' associated with hyperparathyroidism, aneurysmal bone cyst and non-ossifying fibroma. Histologically, they are identified as comprising of osteoclast-like multinuclear cells and hyperplastic mononuclear interstitial cells.
Due to its rarity, the best treatment modality has not been fully described. While there is agreement on the need for excision of the tumour which could either be a subtotal claviculectomy or a total claviculectomy, there is no consensus on the requirement for reconstruction or defect replacement. Since the clavicle is a non-weight bearing bone and said to be functionally expendable, some authors have advocated excision of the clavicle with no attempt at reconstruction based on good functional results of the patient following claviculectomy alone., However, Rubright et al. when examining long-term shoulder function after total claviculectomy reported a gradual loss of some compensatory ability.
Other authors have advocated for defect reconstruction with the benefit of correcting any cosmetic defect, possible protection of vital structures and pain relief., Defect reconstruction following claviculectomy has been done with an autologous fibula graft (vascularised and non-vascularised), clavicle bone cement prosthesis and allograft all with good results.,, Any attempt at biologic reconstruction for clavicular tumours should be reserved for benign tumours and should be avoided in malignant tumours.,, Furthermore, proper follow-up is essential to detect any recurrence. There, however, has not been long-term studies evaluating shoulder function after reconstruction surgery. In our case, the patient was followed up for 5 years with no evidence of recurrence or pulmonary metastasis and radiologic evidence of graft incorporation while retaining excellent shoulder function.
