1/895. A case of leptomeningeal metastasis from lung adenocarcinoma diagnosed by reverse transcriptase-polymerase chain reaction for carcinoembryonic antigen.A case of leptomeningeal metastasis from lung adenocarcinoma is reported. In this case, we evaluated the feasibility of reverse transcriptased polymerase chain reaction (RT-PCR) methods to detect cancer cells in cerebrospinal fluids (CSF). Messenger rna of carcinoembryonic antigen (CEA) was clearly demonstrated in CSF by reverse RT-PCR methods. An immunohistochemical study also demonstrated that tumor cells were stained positive with anti-CEA antibody. This case suggests that RT-PCR for CEA was a sensitive and useful method to diagnose leptomeningeal metastasis from lung adenocarcinoma.- - - - - - - - - - ranking = 1keywords = adenocarcinoma (Clic here for more details about this article) |
2/895. Lung carcinoma presenting as metastasis to intracranial meningioma: case report and review of the literature.Tumor-to-tumor metastasis is rare. The authors report a case of a 52-year-old man with a 1-year history of a right parasaggital meningioma, whose clinical signs were consistent with enlarging meningioma. In preparation for surgery, the routine preoperative chest radiograph revealed a lung mass. Fine-needle aspiration of the mass revealed adenocarcinoma. The patient underwent surgical excision of the intracranial mass, which was thought to be a meningioma. However, pathologic examination revealed a transitional meningioma extensively infiltrated with deposits of metastatic carcinoma from the patient's primary lung tumor. Metastasis to meningioma was therefore responsible for the rapid enlargement of the long-standing meningioma, and caused the first clinical manifestation of primary lung carcinoma. Recurrent metastasis developed at the surgical site 5 weeks later, requiring surgical excision and postoperative radiation to prevent further recurrence. This is a highly unusual presentation for lung carcinoma and, to the authors' best knowledge, is the first such case reported. A review of the published literature revealed 20 other cases of lung carcinoma metastatic to meningioma, which were incidentally discovered on surgery or autopsy.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
3/895. Primary pulmonary meningioma presenting as lung metastasis.A benign primary pulmonary meningioma, an extremely rare tumour, was incidentally detected in a 57-year-old woman in association with a contralateral pulmonary adenocarcinoma. The meningioma was initially suspected to be a metastasis. Both tumours were excised, with excellent outcome. Anatomic features of primary pulmonary meningioma and differential diagnosis are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
4/895. Metastatic meningioma in fine-needle aspiration (FNA) of the lung: cytomorphologic finding.Pulmonary metastasis of intracranial meningioma is rare. We present the cytomorphologic features of such a tumor in a 71 yr-old woman who was found to have multiple lung nodules 13 years following the resection of an atypical intracranial meningioma. Cytomorphologic features were quite distinct and included hypercellularity with large syncytial groups of monomorphic cells with epithelioid morphologic features, often in perivascular arrangements. Occasional intranuclear cytoplasmic inclusions as well as binucleated cells with wispy cytoplasmic extensions were also noted. Immunoperoxidase studies showed focal positivity for epithelial membrane antigen. The differential diagnosis includes primary or metastatic adenocarcinoma, malignant mesothelioma, and melanoma.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
5/895. A staff dialogue on caring for a cancer patient who commits suicide: psychosocial issues faced by patients, their families, and caregivers.Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum during which caregivers discuss a specific cancer patient, reflect on the important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from their fellow staff members. The case presented was of a 31-year-old man who developed adenocarcinoma of the lung with painful bone metastases. His tumor was unresponsive to treatment and he subsequently committed suicide by shooting himself. The verbatim and subsequent discussion raised a number of issues. Staff were devastated by the violent way that he ended his life. They questioned whether more could have been done to prevent this outcome, yet acknowledged that it mirrored the way he had lived, and were able to discuss the values by which we live and die. Some, but not all, felt that the patient had the right to choose how and when to end his life.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
6/895. A case of synchronous double primary lung cancer with neuroendocrine features.We report a case of unique double primary lung cancers with neuroendocrine features in a 63-year-old male smoker. The mass in the left lower lobe (LLL) was a small cell/large cell carcinoma with spindle cell sarcomatous areas and organoid structure. The mass in the left upper lobe (LUL) was a tubular adenocarcinoma with neuroendocrine features including organoid nests showing occasional rosette formation, nuclear palisading in the periphery of the nests and positive immunoreaction for CD56, chromogranin a and synaptophysin. The difference in histological structures between the two masses led us to diagnose double primary lung cancer. The combination of small cell lung carcinoma and spindle cell carcinoma is very uncommon. The relationship between LLL and LUL tumors remains unclear. Multiple lung cancers with neuroendocrine features have only rarely been reported in the literature. The patient in our case died of widespread cancer 2 years and 4 months after the surgery without adjuvant chemotherapy, a longer postoperative survival time than in cases of ordinary extensive small cell lung cancer. Multiple lung cancers with neuroendocrine features are extremely rare and similar cases have not been reported in the literature. Neuroendocrine differentiation has attracted widespread attention and, therefore, examining neuroendocrine features in lung cancers is important.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
7/895. Second lung adenocarcinoma after combination chemotherapy in two patients with primary non-Hodgkin's lymphoma.We report a rare complication of a secondary malignant solid tumor in two patients with non-Hodgkin's malignant lymphoma who developed lung adenocarcinoma after treatments with combination chemotherapies. The first was a case of primary malignant lymphoma of the cervical spinal cord which had been previously treated with radiation to the spinal lesion and combination chemotherapies and entered complete remission. The patient was further treated for relapse with autologous bone marrow transplantation preconditioned with high-dose chemotherapy. Lung adenocarcinoma developed 5.5 years after the initial diagnosis. The second case of malignant lymphoma of lymph nodes did not respond to conventional combination chemotherapies and did not enter remission. Lung adenocarcinoma developed 1 year after the initial diagnosis. The two patients died of lung carcinoma. The clinical profiles of these cases are presented and the causal relationship of primary malignant neoplasms to the second malignant neoplasms is discussed.- - - - - - - - - - ranking = 1.1666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
8/895. Surgical treatment for metastatic lung tumors with incidentally coexisting lung cancer.We report four surgically resected cases of a metastatic lung tumors with incidentally coexisting lung cancer. Two patients (Cases 1 and 2) were admitted for surgical treatment for pulmonary metastases from colon cancer, and the other two (Cases 3 and 4) were for pulmonary metastases from renal cell carcinoma. In only one patient (Case 3), one lesion among the multiple shadows on the preoperative computed tomography examination was rather strongly suspected to be primary lung cancer. In three patients (Cases 1, 2 and 3), one of the resected lesions in each individual case was diagnosed as lung adenocarcinoma by an intraoperative examination using frozen sections, and was later histologically confirmed. In Case 4, one of the resected lesions was postoperatively determined to be lung adenocarcinoma. All coexisting lung cancers, treated with partial resection of the lung, were well-differentiated small-sized adenocarcinoma (T1N0), while the other lesions resected in each case were metastases from the individual cancer. Problems in preoperative diagnosis and surgical treatment for metastatic lung tumors with incidentally coexisting lung cancer are discussed.- - - - - - - - - - ranking = 0.5keywords = adenocarcinoma (Clic here for more details about this article) |
9/895. Pulmonary lymphangitis carcinomatosa and acute pancreatitis: a rare presentation of choledochal cyst.Pulmonary lymphangitis carcinomatosa is an unusual cause of death in a young adult. This case describes an apparently healthy young woman who presented with severe acute pancreatitis, which is a recognized complication of a choledochal cyst. autopsy examination revealed advanced malignancy with poorly differentiated adenocarcinoma penetrating the wall of the choledochal cyst and metastatic adenocarcinoma in the lymph nodes, lungs and kidneys. This case emphasises the unusual presentation of a choledochal cyst with acute pancreatitis and the aggressive nature of malignancy associated with this congenital anomaly.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
10/895. Unilateral metachronous lung cancers in a patient with idiopathic pulmonary fibrosis.The incidence of lung cancer in patients with idiopathic pulmonary fibrosis is much higher than that in general population. We report on a case of large cell carcinoma in association with the additional occurrence, seven months later, of an adenocarcinoma of the lung. Surgical treatment was performed for each cancer, however, the outcome was poor. The association between the two disorders is discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
