Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Area of Science:

Thoracic Surgery
Surgical Pathology
Oncology

Background:

Hamartomas are rare benign tumors, typically found within the lung parenchyma.
Extrapulmonary locations are exceptionally uncommon, posing diagnostic challenges.

Observation:

A 65-year-old male presented with a subpleural tumor in the right lung apex.
Video-assisted thoracic surgery was performed for diagnosis and resection.
Thoracoscopy revealed a chondromatous tumor in the extrapleural space.

Findings:

Histopathological examination confirmed the diagnosis of a hamartoma.
The tumor was located outside the visceral pleura, classifying it as extrapulmonary.
Surgical resection was completed without complications.

Implications:

This case expands the understanding of rare extrapulmonary hamartoma presentations.
Highlights the importance of considering rare diagnoses in thoracic oncology.
Demonstrates the efficacy of minimally invasive surgery for such lesions.
