To the Editor,

Giant cell tumor (GCT) of the bone or osteoclastoma is generally a benign and locally invasive tumor that occurs close to the joint of a mature bone. [1] GCT is an aggressive lesion that behaves in an unpredictable fashion. [2] The rate of recurrence is high and it metastasizes to the lungs, in approximately 2 - 3% of the patients. [3] Metastatic lung nodules can present at the time of initial surgery or develop many years after the appearance of the primary tumor. [4] The primary and metastatic lesions usually have the same histological features of a benign tumor; however, malignant tumors with giant cells have been noted in some cases, on a retrospective review. [5]

Although several cases of GCT with pulmonary metastases diagnosed on biopsy have been described, only four cases diagnosed by fine needle aspiration biopsy have been documented in the cytological literature. All the cases previously described, have presented with multiple pulmonary nodules. [6]

We herein report a case of osteoclastoma metastatic to the lung in an 18 year-old female, who presented with pleural effusion, and a diagnosis of metastatic GCT was established initially, based on the pleural effusion cytology smears. To the best of our knowledge, no similar case has been previously documented in the literature, with such a presentation of pleural effusion and diagnosis based on effusion cytology.

A 16-year-old female with left leg pain was detected to have a left distal femur lesion, in February 2010. The radiograph showed an eccentric lytic lesion in the left distal femur with soft tissue extension. Magnetic Resonance Imaging (MRI) demonstrated a well-defined, smoothly marginated, heterogeneously enhancing mass lesion, involving the epimetaphyseal region of the lower femur, which was hypointense on T1-weighted and predominantly hyperintense on T2-weighted images. She was treated with curettage. A diagnosis of giant cell tumor was made on histopathological examination.

One-and-a-half years later, she presented with a complaint of pain in the anterior chest. A Computed Tomography (CT) scan revealed multiple rounded lesions, with peripheral enhancement and central necrosis in both the lungs. One of the lesions in the left upper lobe and one in the right middle lobe were pleural-based [Figure 1]a-d. All the radiological findings suggested multiple bilateral pulmonary metastases. Two months later, she developed dyspnea and the chest radiograph revealed right-sided pleural effusion, along with the lung lesions [Figure 2]. A pleural tap was performed and 150 ml of pleural fluid was sent for cytopathological evaluation.

Microscopic examination showed many osteoclast giant cells with few interspersed mononuclear cells, numerous foamy histiocytes, and few mesothelial cells [Figure 3]a-c. The findings led us to suspect a diagnosis of GCT, metastatic to the lung, involving the pleura and producing pleural effusion.

The differentials of rheumatoid arthritis, herpes viral infection, giant cell carcinoma, carcinosarcoma, mesothelioma, radiotherapy, granulomatous inflammation, and surgical intervention were considered as they have been rarely associated with the presence of giant cells in pleural effusions. Lack of elongated giant cells and macrophages along with granular necrotic debri ruled out rheumatoid arthritis. There were no nuclear inclusions suggestive of herpetic infection. Giant cell carcinoma, carcinosarcoma, and mesothelioma were excluded because of the absence of bizarre cells. Moreover, the clinical presentation and radiological investigations helped in ruling out all the differentials, including granulomatous inflammation. There was no history of radiotherapy or surgical intervention.

This was followed by fine needle aspiration [Figure 4]a-d and biopsy of the lung lesion [Figure 3]d, which confirmed the diagnosis of metastatic GCT. Both the pleural fluid and fine needle aspiration cytology smears showed attachment of the osteoclastic giant cells to the cohesive groups of mononuclear stromal cells. This was an important feature that helped in reaching the diagnosis of giant cell tumor. There were no cellular and nuclear pleomorphism, bizarre cells, mitoses, necrosis, or osteoid in both the primary and metastatic tumors, thus the important and common differential of osteogenic sarcoma was excluded. No ancillary studies were performed. The patient was started on chemotherapy. Pulmonary metastases were monitored by a chest CT scan and they were stable for 12 months.

Giant-cell tumor of the bone is described as the most unpredictable neoplasm of the skeletal system, which can metastasize despite its benign appearance. [7],[8] Although, it was initially regarded as a benign tumor, the potential for metastasis without undergoing sarcomatous transformation was described by Jaffe et al., in 1940. [5] The incidence of lung metastases varies between 1 and 9.1%. Most of the metastases are diagnosed within the first few years. Some of the authors believe that they might not be found after 10 years. [8],[9],[10] Solitary metastases to other sites like the regional lymph nodes, scalp, and pelvis have also been documented. [2]

Pulmonary metastasis occurs most frequently in recurrent GCT cases and these tumors have the potential to develop malignant biological behavior. [3] The common primary sites with a predilection for metastasis include, the radius, femur, and sacrum. [5],[7],[8] Radiologically aggressive (Enneking stage III) GCTs are more prone to develop lung metastases. [4],[10] Previously, only four cases of metastatic pulmonary GCT have been diagnosed on aspiration cytology. The details of the reported cases are summarized in [Table 1]. [11],[12],[13],[14] Ours is the fifth case that was diagnosed on pleural effusion and aspiration cytology, and confirmed on biopsy.

The proposed pathogenesis behind the formation of lung nodules in cases of benign GCT includes the proliferation of a subpopulation of neoplastic cells, which has metastatic potential, and origin from the tumor emboli derived from the primary tumor. Mostly, metastatic GCTs are detected a year or more after the initial surgery of the primary lesion. Hemorrhage and thrombus formation occur within the bone, during the operation. Any residual GCT not removed at the time of surgery could grow into this thrombus and then break off, leading to an embolic metastasis in the lungs. [4],[8],[10] On account of prevalence of the tumor, microemboli at the time of surgery must be greater than the prevalence of metastases, and other biological factors like immune surveillance and intrinsic biological characteristics of the tumor, seem to play a role. [2]

Malignant GCT and giant cellrich osteosarcoma should be considered in the differential diagnosis of metastatic GCT on aspiration cytology. In addition, rheumatoid arthritis, herpes infection, granulomatous disease, carcinosarcoma, and mesothelioma with osteoclast-like giant cells, should be excluded by appropriate investigations. A history of GCT of the bone is essential for diagnosis due to the rarity for GCT to present with pulmonary metastasis. When such a history is not available, primary lung carcinoma with osteoclast-like giant cells should be considered as a differential. [6]

The natural history of the metastasizing lesions is quite variable. [10] They typically progress, although some may ossify peripherally and remain dormant. Rarely, do metastatic lesions of the lung disappear after biopsy. [2] Both the mononuclear and giant cells express CD 68, parathyroid hormone-like protein (PTH-LP), and matrix metalloproteinases (MMP). Molecular and cytogenetic abnormalities have been shown to be of potentially prognostic value. The Ki-67 labeling index, p53, and MMP expression are higher in GCTs with pulmonary metastasis, particularly in the aggressive type. [3],[6] Surgical excision of the lung metastases is now the widely accepted treatment of choice, with excellent long-term survival. [9] The role of chemotherapy and radiotherapy is debatable. [1] The mortality rates for patients with a GCT metastasizing to the lungs vary from 0 to 37%. [5],[8]

To conclude, in the aspirate of a lung mass or pleural fluid, the presence of mixed osteoclast-like giant cells and bland mononuclear cells should warrant an inclusion of metastatic GCT in the differential diagnosis, particularly in patients with a positive history. This case report highlights the importance of a plain X-ray of the chest and Computed Tomography scan at the time of the first presentation, even in benign giant cell tumors. Follow-up investigations may be performed, as in primary skeletal sarcomas.
