Differentiated thyroid carcinoma is an uncommon malignancy of childhood and adolescence that is unique because it has an overall favorable prognosis despite its relatively high rate of nodal and distant metastases. Total thyroidectomy and positive 131I therapy are recommended for cases with pulmonary metastases. In contrast, anaplastic thyroid cancer is one of the most aggressive malignancies t...

The aim of this study was to evaluate the efficacy of surgical resection of oral tongue cancer (OTC) pulmonary metastases. Between 1977 and 2003, 23 OTC patients who developed 1-3 pulmonary metastases underwent metastasectomy. There were 14 men and nine women with a median age at the time of first metastasectomy of 56 years. All patients had advanced squamous cell OTC with synchronous or metach...

Myxoid/round cell liposarcoma (MRCL), unlike other soft tissue sarcomas, has been associated with unusual pattern of metastasis to extrapulmonary sites. In an attempt to elucidate the clinical features of MRCL with metastatic lesions, 58 cases, from the medical database of Keio University Hospital were used for the evaluation. 47 patients (81%) had no metastases, whereas 11 patients (11%) had m...

INTRODUCTION In recent years, there has been debate regarding the diagnostic accuracy of computed tomography (CT) in the identification of lung metastases and the need for lung palpation to determine the number of metastatic nodules. The aim of this study was to determine in which patients the CT scan was more effective in detecting all metastases. METHODS We studied all patients who underwen...

A series of investigations was employed to determine if metastases of intraocular melanomas could be induced by experimental manipulations. Syngeneic B16F10 melanoma cells transplanted intracamerally into C57BL/6 mice produced progressively growing intraocular tumors, yet formed only occasional pulmonary metastases. Neither enucleation nor mechanical manipulation of the melanoma-containing eye ...

CONTEXT Soft tissue sarcomas generally first metastasize to the lungs followed by the involvement of other sites such as lymph nodes and bones as part of the disseminated disease. Cerebellar and pancreatic metastases from tumors of mesenchymal origin such as soft tissue sarcomas are exceptional, more so in the absence of pulmonary metastases. CASE REPORT A previously treated case of chest wal...

Title: Peri-operative chemotherapy in the management of resectable colorectal cancer pulmonary metastases

Introduction Testicular germ cell tumors with somatic-type malignancy, wherein teratomas transform into sarcomas, is drug resistant and has a poor prognosis. Case presentation A 43-year-old man presented left testicular tumor, multiple pulmonary metastases, mediastinal para-aortic lymph node metastases. The were diagnosed as tumors. After bleomycin, etoposide, cisplatin chemotherapy; right uppe...
