Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

The Bronchial Tree01:23

The Bronchial Tree

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features01:24

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Area of Science:

  • Pulmonology
  • Oncology
  • Pathology

Background:

  • Carcinosarcoma is a rare and aggressive mixed tumor originating in the lung.
  • These tumors exhibit both epithelial (carcinoma) and mesenchymal (sarcoma) malignant components.

Observation:

  • A 65-year-old male presented with cough and a right lower lobe opacity on imaging.
  • Surgical resection revealed a large, endobronchial tumor.

Findings:

  • Histopathological examination confirmed a mixed tumor with non-small cell carcinoma and malignant mesenchymal elements.
  • The tumor's endobronchial location and mixed histology are characteristic of lung carcinosarcoma.

Implications:

  • Accurate radiologic and histopathologic diagnosis is crucial for appropriate patient management.
  • Understanding the dual nature of lung carcinosarcoma aids in treatment planning and prognosis assessment.
