Carcinoma ex pleomorphic adenoma is an exceedingly rare neoplasm of the minor salivary gland. Prognostic parameters are recurrence, capsular invasion, and metastasis. We present a case of carcinoma ex pleomorphic adenoma with pulmonary metastasis to emphasize that patients treated for this condition should be investigated for distant metastasis.

BACKGROUND This study assessed the efficacy of pulmonary metastasectomy for synovial sarcoma in adult patients. METHODS Fifty patients, diagnosed with pulmonary metastasis from June 1990 to August 2010, were reviewed retrospectively. Twenty-eight patients underwent complete pulmonary metastasectomy, and their survival was evaluated. Age, sex, time to metastatic progression, laterality, number...

Osteosarcoma is a common and highly malignant tumour in children and teenagers that is characterized by drug resistance and high metastatic potential. Patients often develop pulmonary metastasis and have a low survival rate. However, the mechanistic basis for pulmonary metastasis remains unclear. To identify key gene and pathways associated with pulmonary metastasis of osteosarcoma, the authors...

BACKGROUND: Surgical resection of isolated hepatic or pulmonary colorectal metastases prolongs survival in selected patients. But the benefits of resection and appropriate selection criteria in patients who develop both hepatic and pulmonary metastases are ill defined. STUDY DESIGN: Data were prospectively collected from 131 patients with colorectal cancer who underwent resection of both hepati...

OBJECTIVE Natural killer (NK) cells represent the third largest population of lymphocytes, and they play an important role in immune surveillance against tumors. The lungs are a common metastatic site for anaplastic thyroid cancer (ATC), and metastasis is one of the most frequent causes of mortality in this type of cancer. In the current study, we evaluated the effects of NK cell-based immunoth...

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...

BACKGROUND Hepatocellular carcinoma (HCC) is seldom resectable due to advanced status. Even though hepatectomy is feasible, a large proportional of patients may still develops extrahepatic recurrence. Pulmonary metastasis is the most common site of extrahepatic spread. Few articles have discussed the benefit of resection for lung metastasis after curative hepatectomy. We evaluated the general i...

BACKGROUND As a type of primary malignant bone tumor, osteosarcoma has high incidence and poor prognosis, and is predisposed for pulmonary metastasis. The abnormal expression of P15 gene directly participates in the invasion of various cancers. Therefore, this study investigated the gene mutation of P15 in both primary lesion and pulmonary metastasis lesion of osteosarcoma in a rat model, in an...

Prostate adenocarcinoma is the most common newly diagnosed cancer in males. Pulmonary and pleural metastasis are not uncommon on autopsy, but malignant effusions are not common clinical findings. There are no current recommendations to guide prostate specific antigen level assessment in pleural fluid. A 73 yo w/prostate cancer presented with complaints of subacute worsening of exertional dyspne...
