Author：Title：A case report of unclassified pediatric microcystic parenchymal maldevelopment of the lungAnnouncement information: Vol: 37 Issue: 4 Page: 205-209Keyword：pediatric lung tumor, congenital cystic lung disease, microcystic parenchymal maldevelopmentAn abstract：A four-year-old boy presented with vomiting as the chief complaint. Chest CT showed a mass with calcification in the right middle lobe of the lung. Mediastinal teratoma or pulmonary hamartoma was suspected. Hence, right middle lobectomy was performed under video-assisted thoracic surgery for diagnostic treatment. Pathological findings were negative for both neoplastic lesions and inflammatory lung lesions, and the lesions were considered to be related to congenital cystic lung diseases; however, the case was atypical. Congenital cystic lung disease includes various lesions, and there are some cases in which a definite diagnosis is difficult owing to the presence of multiple lesions resulting from their embryological characteristics.
