Congenital Pulmonary Airway Malformation (CPAM) is characterized by what type of tissue?

• A. Normal lung tissue development
• B. Hamartomatous lung tissue
• C. Fibrous lung tissue
• D. Infected lung tissue

Answer: (B)

Congenital Pulmonary Airway Malformation (CPAM) is characterized by the presence of hamartomatous lung tissue. This abnormal tissue growth is a result of developmental errors that occur during lung formation. In CPAM, the lung tissue is disorganized and includes cystic lesions that can vary in size, which may disrupt normal respiratory function. Hamartomas are benign tumors made up of an abnormal mixture of cells and tissues that are normally found in that particular organ. In the case of CPAM, these tissues may include respiratory epithelium, cartilage, and other components of lung architecture, which accumulate and can lead to varying degrees of respiratory distress in the affected neonate. The other types of tissue mentioned in the options do not accurately describe CPAM. Normal lung tissue development would reflect typical lung organogenesis, which is not applicable to CPAM. Fibrous lung tissue suggests a scarring or fibrotic process, which is not a characteristic of CPAM. Infected lung tissue would indicate the presence of an infectious process, rather than a congenital malformation of lung structure. Therefore, the defining feature of CPAM is indeed the presence of hamartomatous lung tissue.
