Rare presentation of giant cell tumor of bone in the lateral end of the clavicle

Abstract

Patient: Male, 30Final Diagnosis: Giant cell bone tumorSymptoms: Bone swelling • painMedication: —Clinical Procedure: —Specialty: OncologyObjective:Unusual clinical courseBackground:Cooper first reported giant cell tumors (GCT) in the 18th century. The clavicle is a rare site for tumors. Metastatic tumors are more common than benign. This is the first case of GCT lateral end of clavicle to be reported in the literature.Case Reports:A 30-year-man was admitted with a 1-year history of progressively increasing swelling and pain over the left lateral end of the clavicle.The plain radiograph and PET scan revealed an expansile radiolucent lesion in the lateral end of the clavicle. Swelling was epiphsio-metaphyseal in location. It demonstrated geographical type of destruction with a narrow zone of transition. There was no periosteal reaction or soft-tissue component. The mitotic activity was found to be 0–1/10 HPF. Diagnosis was confirmed histopathologically. A wide excision of the mass, including 3 cm of healthy tissue of the clavicle, was performed.Conclusions:The presence of an expansile lytic lesion of the lateral end of the clavicle should be taken seriously and complete radiological and histopathological investigation should be done and giant cell tumor of the bone should be kept in mind despite its rarity.

Giant cell tumour of clavicle: Occurrence of a common tumour in a rare location

“…After extensive search of literature it was found that there are very few case reports describing giant cell tumors of clavicle [8], [9], [10]. Due to the paucity of the available literature no definite treatment guidelines are available on the management of giant cell tumor of clavicle.…”

Giant cell tumor of the clavicle: report of a case in a rare location with consideration of surgical method

“…In contrast, en-bloc resection without any reconstruction is performed for GCTs in expendable bones such as the distal ulna, proximal fibula, or iliac wing. Because there are only a few reports of clavicular GCTs [ 16 – 19 ], the optimal surgical method has not reached consensus. However, it seems that claviculectomy, either partial or total, might be a good option for clavicular GCTs.…”
