1/1046. Small cell lung cancer accompanied by lactic acidosis and syndrome of inappropriate secretion of antidiuretic hormone.Lactic acidosis is a rare complication in lung cancer. We report a case of lung cancer accompanied by both syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and lactic acidosis. A 70-year-old man was referred to our hospital for examination of a left hilar mass shadow on a chest x-ray film. Small cell lung cancer (SCLC) was demonstrated by brushing the bronchial mucosa of the left lower lobe bronchus. His laboratory data showed SIADH and lactic acidosis that were probably due to SCLC. Fluid restriction improved SIADH, and combination chemotherapy for SCLC improved the lactic acidosis although the tumor size did not change.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/1046. Intrathoracic suture abscess after lobectomy for early lung cancer.Intrathoracic suture abscess may occur around sutures on the pleura or in the lung parenchyma, although it is rare to encounter such cases clinically. We report on a 68-year-old woman with an intrathoracic (extrapulmonary) suture abscess, which was discovered on a chest x-ray film one year after right-middle lobectomy for early lung cancer. The abscess was removed surgically, and the postoperative course was uneventful. Pathological examination showed that it was caused by braided polyester sutures.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
3/1046. Ocular adnexal granulocytic sarcoma as the first sign of acute myelogenous leukemia relapse.PURPOSE: To report a case of granulocytic sarcoma involving the eyelids and caruncles after bone marrow transplantation. methods: Case report. A 30-year-old man with acute myeloid leukemia in remission developed multiple friable eyelid and caruncular lesions in addition to two cutaneous lesions on the chest wall and right axilla approximately 3 months after a successful autologous bone marrow transplant. RESULT: Pathologic examination was consistent with granulocytic sarcoma. CONCLUSION: This condition should be considered in the differential diagnosis of cutaneous or eyelid masses in patients with a history of leukemia.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
4/1046. A case of a malignant melanoma with late metastases 16 years after the initial surgery.We report a case of a pulmonary metastasis 16 years after the initial surgery for a malignant melanoma. The patient was a 58-year-old Japanese man. In 1976, he had a pigmented skin lesion with a diameter of 8 mm on his right third finger. He received an amputation of the finger and a dissection of the right axillary. Histological examinations of the tumor revealed a feature of a malignant melanoma with infiltration of the papillary layers of the dermis, 1.5 mm in thickness. The histological subtype was considered to be an acral lentiginous melanoma with a mixed spindle-epithelioid cell pattern. There was no regional lymph node metastasis. In December 1992, when he was 74-years-old, a round tumor in the left lower lung was discovered by chest radiography. In February 1993, he received a left lower lobectomy of the lung. Histological examination revealed a feature of a malignant melanoma with predominantly epithelioid cells and this was considered to be a metastasis from the initial skin lesion. Five months after the lobectomy, he died from a hemorrhage of a metastatic brain tumor. This case indicated the importance of periodic, life-long follow-up in treating malignant melanomas.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
5/1046. Cerebral metastasis presenting with altitudinal field defect.A 75-year-old man presented with a unilateral inferior altitudinal visual field defect and a history of weight loss and night sweats. The acuity in the affected eye was 20/200, otherwise his ocular examination was normal. neuroimaging demonstrated a post-fixed chiasm, with a frontal metastasis compressing the intracerebral portion of the optic nerve. A chest x-ray showed classical cannon ball lesions, secondary to malignant melanoma. This is the first case report of an intracerebral tumor producing an inferior altitudinal field defect.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
6/1046. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
7/1046. 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 = 1keywords = chest (Clic here for more details about this article) |
8/1046. Pulmonary intravascular lymphomatosis: presentation with dyspnea and air trapping.Intravascular lymphomatosis (IVL) is a rare lymphoid neoplasm that is typically of B-cell lineage and characterized by proliferation of malignant cells within small arterioles, capillaries, and venules. We report a patient with pulmonary IVL who presented clinically with progressive dyspnea, fever, and a dry cough. Pulmonary function tests revealed a marked decrease in diffusion capacity with airflow obstruction and severe air trapping. High-resolution CT (HRCT) of the chest with inspiratory and expiratory images revealed mosaic attenuation consistent with air trapping. Transbronchial biopsies revealed the diagnosis of IVL with capillary expansion in the alveolar and peribronchiolar interstitial tissue. IVL should be considered in the differential diagnosis of a patient with an interstitial lung disease, air trapping on pulmonary function tests, and mosaic attenuation on HRCT. Transbronchial biopsies may be the initial diagnostic procedure of choice.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
9/1046. Pulmonary small cell carcinoma associated with sarcoid reactions: report of a case.A 45-year-old male was admitted to our hospital for investigation of a nodular shadow in segment 5 of the right lung on a chest computed tomogram. A right middle lobectomy with mediastinal lymph node dissection was performed under a diagnosis of lung cancer, and histologic examination confirmed small cell carcinoma. There were sarcoid reactions in the resected lymph nodes and the lung parenchyma, but no signs of systemic sarcoidosis were evident. Sarcoid reactions are rarely observed in the regional lymph nodes draining malignant tumors. Moreover, while they are most common in squamous cell carcinoma of the lung, they extremely rare in small cell carcinoma. To our knowledge, this is only the third report of this unusual entity in the English and Japanese literature.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
10/1046. Angiosarcoma of the chest wall.Angiosarcoma is a rare and highly malignant tumor of vascular origin. The causative factors include trauma, radiation, foreign bodies, thorium dioxide, and viral infections. We report a case of angiosarcoma occurring in a thoracotomy incision 17 years after operation for stage I lung cancer.- - - - - - - - - - ranking = 4keywords = chest (Clic here for more details about this article) |
