Abstract
|
|
|
Pulmonary blastoma is a very rare, primary, malignant neoplasm of the lung. The tumor typically is large, well-defined mass and arises in the periphery of the lung.
Histologically, it resembles fetal lung tissue evoking the concept that these tumors are drived from the primitive pluripotential pulmonary blastema, but controversy also exit about the nature of this tumor.
Clinical evaluation is inconsistant and unreliable as to the diagnostic determination of the tumor type and degree of malignancy. Therefore, diagnosis is usually based on histologic findings.
The prognosis after adequate resection appears to be better than for other malignant tumors of the lungs.
We experienced a case of pulmonary blastoma occurring in 56-year-old female. She was hospitalized for evaluation of an abnormal shadow in the left lower lung field which found incidentally on chest roentgenogram.
We approached the lesion though left posterolateral thoracotomy and performed the left lower lobectomy.
The microscopic findings of resected specimen revealed characteristic appearance of pulmonary blastoma.
The postoperative course was uneventful without complication.
