[Malignant transformation of lung hamartomas]

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Lung hamartomas are benign tumors rarely undergoing malignant transformation.
• Analysis of literature and author's materials on malignant lung hamartomas.

Observation:

• Detailed case report of a patient with malignant transformation of a lung hamartoma.
• The pathological process showed extensive involvement and regional lymph node metastasis.
• Unusual metachronous occurrence of multiple rare primary tumors was noted.

Findings:

• Confirmed malignant transformation of a lung hamartoma.
• Demonstrated metastasis to a regional lymph node via the epithelial portion.
• Documented the rare event of metachronous multiple primary tumors.

Implications:

• Highlights the importance of vigilance for malignant changes in lung hamartomas.
• Contributes to understanding rare oncological presentations and metastatic pathways.
• Underscores the complexity of diagnosing and managing patients with multiple primary neoplasms.
