Giant cell tumor of patella: A case report and review of literature
Journal of Emergency Practice and Trauma
Objective: Patella is a sesamoid bone which develops in the quadriceps tendon. It is an uncommon site for neoplasms. The most common primary tumors which involve patella are benign. These include chondroblastoma, giant cell tumor (GCT) and aneurysmal bone cyst. Malignant lesions are less common in patella. These encompass metastasis, osteosarcoma and hemangioendothelioma. The most common complaint in patients of GCT patella is anterior knee pain. Early diagnosis and optimal management are necessary for improving survival rate in these patients. Case Presentation: The authors present a case report of GCT of patella in a 16-year old child. Incisional biopsy was done to confirm the diagnosis. Further radiological examination showed that the tumor involved almost whole of the patella. Hence, surgical management in the form of patellectomy and extensor mechanism repair was done to improve the outcome of the disease. The patient did not have any clinical or radiological symptoms at the en...

This study reports 42 cases of histologically proven and radiographically correlated primary patellar tumors. Despite diverse histologic diagnoses, the radiographic appearances of benign as opposed to malignant patellar neoplasms are essentially indistinguishable. Although the literature suggests that giant cell tumor is the most frequent benign tumor of the patella, the most common benign neoplasm in this series is chondroblastoma (16 cases). Only four primary malignant lesions were encountered, three cases of lymphoma and one case of hemangioendothelioma. Since 38 (90%) of the 42 cases were benign, a benign etiology should be strongly favored, notwithstanding the radiographic appearance, whenever a primary patellar tumor is encountered.

Giant cell tumor of bone also known as osteoclastoma is a distinct clinical, roentgenographic and pathologic entity with speci•c characteristics. It is a benign but locally aggressive neoplasm of the epiphyseal or metaphyseal-epiphyseal region of long tubular bones extending to the articular surface. It usually occurs after skeletal maturation and is one of the rare bone tumors that more frequently affects women. We report here a case of giant cell tumor originating from the right patella diagnosed on •ne needle aspiration cytology.
Patellar Giant-Cell Tumor: a Case Report
The Journal of Experimental Life Sciences
Giant cell tumor (GCT) found mostly in the long bones metaphysis or epiphysis. GCT usually occur between the ages of a third and fourth decade and locally aggressive. Giant-Cell Tumor seldom affects the patella. Multicentric forms rarely reported. A fourteen-year-old female with a lump at her left patella since one-year associated with slight pain that aggravated by activity for six months. Plain X-ray left knee AP, and lateral views reveal expansile lytic lesion in left patella with thinning of the anteroinferior cortex and sclerotic septa within. MRI of left knee shows approximately 3x2x2 cm heterogeneous lobulated expansile soft tissue mass in left patella extending up to the patellofemoral joint with fluid-fluid appearance. From fine needle aspiration cytology, resulting giant-cell tumor with the differential diagnosis of an aneurysmal bone cyst. The operation already performed. Curettage, bone graft, and a biopsy taken. An immunocytochemical smear was performed and confirmed as a patellar giant-cell tumor. Six months after excision of the tumor, the patient complained no arthralgia and have a full range of motion for the knee.
Giant-Cell Tumor of the Patella: Case Report
The Journal of medical research, 2018
Giant cell tumor (GCT) is a tumor found most often in the ends of long bones and is essentially located in the epiphyseal or metaphyseal or epiphyseal equivalent portions of bone. It is a locally aggressive neoplasm, generally arising in adults between the ages of 20 and 40 years, clinically possessing metastatic potential. The classic location is around the knee joint and it starts in the epiphysis spreading to the metaphysis and may erode the cortex in 25% of the cases. Approximately 10% of these tumors have a malignant course. The patella is a rare site with a reported incidence of less than one percent. Rare multicentric forms have been reported. A 14-year-old female from Malang, East Java, presented with a one year history of a progressively growing mass in the left patella associated with slight pain that has been aggravated with activity for 6
Giant Cell Tumor of the Patella: An Uncommon Site
Nepalese Journal of Radiology, 2018
Primary tumors of the patella are rare of which Giant cell tumor is the most frequent. Patient usually presents with pain in anterior knee and swelling. Radiologically, Giant cell tumor usually presents as a well defined lytic lesion with no sclerotic margin, no periosteal reaction and no soft tissue involvement unless complicated by fracture and shows enhancement on post-contrast study. Herein, we report the case of a 31-year female with giant cell tumor of the patella (GCT) with its clinical and radiological features.
Late Presentation Of G.C.T. Of The Patella
The Internet Journal of Orthopedic Surgery, 2008
Primary giant-cell tumor of the patella is a rare entity with only a handful of cases reported in the world literature and none presenting at a late stage.Methods: A 23 years old female patient presented with a knee swelling at 2.5 years and was diagnosed as a primary giant cell tumor of the patella. Total patellectomy was done and the specimen subjected to histopathological investigation. The patient was put on post operative physiotherapy and was followed up regularly.Results: Histology reports suggested a primary giant cell tumor of the bone. The patient achieved excellent functional results at last follow up of four years. Conclusions: Giant cell tumor of the patella even if presenting late with massive involvement may be managed with total patellectomy to achieve good to excellent results.

Primary patellar neoplasms are rare, comprising 0.12% of primary bone tumours; thus, no standardised treatment related to staging exists. 70%-90% of primary patellar neoplasms are benign or intermediate with giant cell tumour (GCT) being the most common. GCTs are locally aggressive, have a high recurrence rate and metastasise in 1%-2%. We report the case of a 23-year-old man with histologically confirmed recurrent GCT of the patella to demonstrate that aggressive surgical management options described in the literature, such as patellectomy with or without complex reconstruction, may be excessive and cause patients undue morbidity. Initially, the patient underwent intralesional curettage with excellent recovery, but presented again with a local recurrence within a year. A further definitive operation was performed which included excision of the inferior pole followed by curettage of the patellar body and artificial bone grafting. The patient made a good recovery and at 5-year follow-...
Giant Cell Tumor with Secondary Aneurysmal Bone Cyst of the Patella: A Case Report
Cureus
A 15-year-old girl presented with pain and swelling on the anterior aspect of the right knee for one year. The radiological evaluation with x-rays and magnetic resonance imaging suggested a benign aggressive lesion of the right patella with a cortical breach. Core needle biopsy of the lesion revealed it to be a giant cell tumor (GCT). She was treated with total patellectomy and end-to-end repair of quadriceps to the patellar tendon. The histopathological report of the whole specimen revealed it to be a GCT with secondary aneurysmal bone cyst (ABC). After 24 months, she was asymptomatic, and there was no evidence of local recurrence or distal metastasis. An extensive review of the literature revealed only four cases of combined GCT with secondary ABC in the patella. Though rare, GCT with secondary ABC of the patella should be kept as a differential diagnosis for anterior knee pain and swelling in young patients. The diagnosis is solely based on histopathological findings. It is imperative to obtain a precise tissue diagnosis in the preoperative period to plan appropriate treatment.
