Orthotopic Implantation and Peripheral Immune Cell Monitoring in the II-45 Syngeneic Rat Mesothelioma Model
Published on: October 2, 2015
Summary
This study on pleural mesothelioma found localized benign tumors in women and diffuse malignant types in men. Gross appearance is key for prognosis, differentiating benign from lethal forms.
Area of Science:
- Oncology
- Thoracic Surgery
- Pathology
Background:
- Primary pleural mesothelioma is a rare malignancy requiring accurate classification.
- Understanding tumor presentation and behavior is crucial for patient outcomes.
Observation:
- A series of nine patients with primary pleural mesothelioma were analyzed.
- Tumor types included localized benign (3 women), diffuse malignant (5 men), and multiple discrete (1 woman).
- Seven patients presented with pleural effusion, but cytology was unhelpful for diagnosis.
Findings:
- Localized benign mesothelioma showed relatively favorable clinical behavior.
- Diffuse malignant mesothelioma exhibited a more aggressive and lethal course.
- Despite asbestos exposure history in three patients, none had asbestosis or hypoglycemia.
Implications:
- Gross morphological classification aids in clinical management and prognosis of pleural mesothelioma.
- Thoracotomy was necessary for diagnosis in all cases due to limitations of cytologic studies.
- Further research into diagnostic methods and therapeutic strategies for different mesothelioma subtypes is warranted.

01:13Pleura of the Lungs
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...
01:30Pleural Disorders: Types and Brief Description
The pleura is a vital part of the respiratory system. It's a double-layered membrane surrounding the lungs and lining the chest cavity. The two layers of the pleura are:
01:25Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

01:27Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:08Pneumothorax II: Pathophysiology
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
