They are classified into two subcategories; typical and atypical carcinoids with the latter tending to grow faster. Historically, open thoracotomy was the standard approach for pulmonary resection.

A Case Report of Giant Bilateral Wolffian Adnexal Tumor.

Background: Wolffian adnexal tumor is a rare type of tumor that was first discovered and reported by Karim-inejad in 1973. Wolffian adnexal tumor lacks specific clinical manifestations and its histological morphology is similar to various other tumors, making it highly prone to misdiagnosis. To enhance our understanding of this disease, we hereby report a case of Wolffian adnexal tumor diagnosed and treated in our hospital.

Malignant pleural mesothelioma treated with cytoreductive video-assisted thoracic surgery plus hyperthermic intrathoracic chemotherapy: a case report.

Background: Malignant pleural mesothelioma (MPM) is primarily treated with a combination therapy based on lung pleurectomy in the early stage or pemetrexed combined with platinum-based chemotherapy in the late stage. However, these standard therapies do not significantly improve survival and are associated with significant adverse reactions.

Case Description: In February 2017, a 63-year-old male patient was admitted to Department of Thoracic Surgery, The Third Affiliated Hospital of Chongqing Medical University coughing for 1 month and experienced chest tightness and chest pain for 2 days.

Renal Cell Carcinoma Presenting As Isolated Malignant Pleural Effusion: A Case Report.

Renal cell carcinoma (RCC) of the clear cell type is the most common form of renal malignancy. Malignant pleural effusion (MPE) as the initial presentation of RCC is very rare. This case report presents a case of RCC that initially manifested as a pleural effusion, without the typical symptoms of flank pain, hematuria, or a palpable abdominal mass.

[Treatment of Secondary Spontaneous Pneumothorax due to Tumor Rupture:Report of a Case].

A 64-year-old man undergoing chemoradiotherapy for lung adenocarcinoma with systemic metastases was admitted for a malignant pleural effusion in the left thoracic cavity that necessitated a drainage and pleurodesis with talc. After pleurodesis, an air leak occurred, which led to surgical intervention. Preoperative computed tomography (CT) scans and intraoperative findings revealed multiple nodules in the lungs and a fistula due to ruptured tumor.

Iatrogenic Budd-chiari Syndrome from Misplacement of Right Internal Jugular Central Vein Catheter: A Case Report.

Introduction/background: Budd-Chiari syndrome is a rare entity that is caused by an obstruction of the flow in the hepatic veins or inferior vena cava.

Thoracic and Cardiovascular Imaging Manifestations of Lupus.

Systemic lupus erythematosus (SLE), commonly referred to as lupus, is a widely prevalent chronic autoimmune disease that can affect any organ system in the body. Although the pathogenesis of this disease is rather complex and poorly understood, ultimately there is an overproduction of multiple self-reactive antinuclear antibodies. These autoantibodies are one of the laboratory hallmarks of the diagnosis and disease activity of SLE.

Systematic Review of Image-guided Thermal Ablation for Treatment of High-Risk Patients with Stage I Non-Small Cell Lung Cancer.

Image-guided thermal ablation (IGTA) applied to pulmonary pathology is an alternative to surgery in high-risk patients with stage I non-small cell lung cancer (NSCLC). Its application to lung neoplasm was first introduced in 2001 and has been implemented to treat metastatic disease to the lung or in select medically inoperable patients with peripheral stage I NSCLC. IGTA may also be an alternative to treat stage I NSCLC in non-operable patients with interstitial lung disease in whom a radiation modality is deemed too high risk.
