Summary
This case report details a rare diffuse pulmonary hamartoma that spread along the bronchial tree. This unusual presentation required a left pneumonectomy for treatment.
Area of Science:
- Pulmonology
- Pathology
- Oncology
Background:
- Pulmonary hamartomas are typically solitary, benign lung nodules.
- They are composed of disorganized mature mesenchymal elements.
Observation:
- A 48-year-old man presented with dyspnea and chest pain.
- A unique hamartoma case exhibited diffuse growth along the bronchial tree and into the lung parenchyma.
- Endobronchial polypoid lesions were noted.
Findings:
- Histological diagnosis confirmed hamartoma with mature adipose tissue, cartilage, and muscle.
- The lesion diffusely infiltrated the bronchial tree and lung parenchyma.
- A left pneumonectomy was performed due to the extensive nature of the tumor.
Implications:
- This case highlights a rare, diffuse variant of pulmonary hamartoma.
- It underscores the importance of considering atypical presentations of lung tumors.
- Surgical intervention may be necessary for extensive or diffuse lesions.
