Metachronous multiple thymoma with different clinical behavior and pathological findings.

A 70-year-old woman presented with a nodule in the left hilum on a chest radiograph 3 years before. Another mass emerged caudal to the initial nodule and was diagnosed as thymoma. A surgical specimen revealed two components: an encapsulated rostral nodule and a caudal mass invading the left lung.

Simultaneous pulmonary metastases from colon and prostate cancer to the same lobe.

Simultaneous pulmonary metastases from different primary tumors to the same lobe are extremely rare, and we herein report the case. Surgical specimen of the pulmonary metastasis from colon cancer contained two additional nodules that were confirmed as metastases from prostate cancer. Pulmonary metastasis from prostate cancer rarely forms nodules, and there is a discrepancy in the incidence of pulmonary metastases between autopsy and clinical findings.

Multiple granulomatous lung lesions in a patient with Epstein-Barr-virus-induced mononucleosis and new-onset systemic lupus erythematosus: a case report.

Introduction: Granulomatous lesions are commonly encountered abnormalities in pulmonary pathology, and often pose a diagnostic challenge. We report an unusual case of granulomatous lung disease with uncommon characteristics, which developed following Epstein-Barr-virus-induced mononucleosis and new-onset systemic lupus erythematosus. We aim to highlight a diagnostic approach for the condition and to raise awareness of the possibility of it being related to the immunological reaction caused by Epstein-Barr virus infection.

Only surgical resection can identify the second primary lung cancer out of the metastasis after gastric cancer surgery.

Objective: Solitary pulmonary lesions (SPLs) in patients with a history of malignancy require not only the distinction between benign and malignant, but also that between metastatic and primary lesions. We aim to establish the clinical strategy for the treatment of a solitary pulmonary lesion that is detected during the postoperative surveillance for gastric cancer.

Methods: We retrospectively examined the clinical records of the patients who underwent curative resection for gastric cancer between January 1999 and December 2009.

An evaluation of the surgical morbidity of polyglycolic acid felt in pulmonary resections.

Purpose: Several methods using various materials have so far been reported to repair pulmonary air leaks, which is an essential problem in general thoracic surgery. Although the efficacy of these materials has been often discussed, the safety has only rarely been examined. This study evaluated the safety of polyglycolic acid (PGA) felt, one of the most commonly materials employed at this institute.

A case of IgG4-related lung disease associated with multicentric Castleman's disease and lung cancer.

A 67-year-old man with submaxillary lymphadenopathy diagnosed as reactive follicular hyperplasia of the lymph node was referred to us for pulmonary evaluation. Pathological findings of the lung and hilar lymph node biopsies showed the histological feature of Castleman's disease (CD). Interestingly, infiltrated plasma cells had strong immunoreactivity for IgG4.

[A case of primary pulmonary nocardiosis with multiple pulmonary nodules successfully treated with moxifloxacin].

A 18-year-old man was admitted with fever. His chest radiograph and CT scan showed consolidation shadow in the right middle lobe and multiple nodules in both lungs. He was treated with meropenem and minocycline.

Feasibility study of adjuvant chemotherapy with gemcitabine and split-dose cisplatin for completely resected non-small-cell lung cancer.

Introduction: Recent clinical trials have shown significant survival benefits from postoperative adjuvant chemotherapy for resected non-small-cell lung cancer (NSCLC). However, due to the comparatively low compliance in recent clinical trials, this study investigated the feasibility of adjuvant chemotherapy with gemcitabine plus split-dose cisplatin for completely resected NSCLC.

Methods: Gemcitabine at a dose of 1000 mg m(-2) and cisplatin at 40 mg m(-2) were given intravenously on days 1 and 8 every 4 weeks for a maximum of four cycles.

The common trunk of the left pulmonary vein injured incidentally during lung cancer surgery.

We report a case in which the common trunk of the left pulmonary vein was injured incidentally due to a misunderstanding of the anatomy. After cutting the trunk, we recognized that the vessel included not only the superior but also the inferior component of the pulmonary vein. The cut end of the trunk and the left atrium were successfully anastomosed without any surgical morbidity.

Prognostic significance and possibility in guiding adjuvant therapy of the pleural lavage cytology in patients with non-small cell lung cancer.

Pleural lavage cytology (PLC) has been reported to be a significant prognostic factor in patients with operable non-small cell lung cancer (NSCLC). PLC may detect micro metastasis in patients without apparent pleural effusion or dissemination. Although many studies have reported PLC as a good predictor of postoperative recurrence, its role in the staging of NSCLC and in determining adjuvant therapy is still controversial.

[A case of solitary nodular pulmonary amyloidosis].

A 64-year-old man without respiratory symptoms was introduced to our hospital because of a nodule of 20 mm in diameter found in the left lung in a periodic health examination. The chest radiograph and CT scan showed a well-defined nodule in the middle of the left lung field, and enlarged mediastinal lymph nodes. Lung cancer was suspected, and transbronchial and CT guided biopsies were performed, but did not lead to a definitive diagnosis.

A small, incidentally detected pancreatic somatostatinoma: report of a case.

We report an asymptomatic 72-year-old woman with a small, incidentally detected, pancreatic somatostatinoma. The tumor, measuring 1 cm in diameter, showed a hypervascular pattern of contrast enhancement on computed tomography, and was found angiographically to receive a blood supply from the posterior superior pancreaticoduodenal artery. The results of preoperative hormonal assays all were normal.
