Insights
Pulmonary hamartomas, common benign lung tumors, can present as giant masses in children. This case highlights a rare giant pulmonary hamartoma in a 5-year-old, successfully treated with surgery.
Area of Science:
- Pulmonology
- Pediatric Oncology
- Surgical Pathology
Background:
- Pulmonary hamartomas are the most frequent benign lung neoplasms in adults.
- Typically, they are asymptomatic due to small size and slow growth.
- Giant pulmonary hamartomas are rare, especially in pediatric populations.
Observation:
- A 5-year-old child presented with a giant lung mass.
- The mass led to recurrent right-sided pneumonia.
Findings:
- Surgical resection with middle lobectomy was performed.
- Histology confirmed a pulmonary hamartoma.
- The tumor showed predominant adenofibromatous and lipomatous differentiation.
Implications:
- Giant pulmonary hamartomas, though rare, should be considered in pediatric patients with recurrent pneumonia.
- Surgical intervention is effective for symptomatic large hamartomas.
- Understanding histological variants aids in diagnosis and management.
Abstract:
Pulmonary hamartomas are the most common benign tumors of the lung in adults. They are usually asymptomatic because of their small size and their slow-growing character. We report the case of a 5-year-old child presenting with a giant lung mass causing recurrent right pneumonia. Surgical resection with middle lobectomy was performed. Final histology revealed pulmonary hamartoma with predominant adenofibromatous and lipomatous differentiation.
