Invasive thymoma in a child: a rare case report.
Thymomas are neoplasms of the anterior mediastinum and generally occur between the fourth and sixth decades of life. In children, they are rare, with few reported cases. We describe a 9-year-old boy with invasive thymoma treated successfully by surgery alone. The patient was previously healthy and under treatment for a community-acquired pneumonia. A chest radiograph showed an opacity at the left lung base, and thoracic computed tomographic scan showed a mass with thick walls and liquid content situated in the lingula with no cleavage plane with the mediastinum. The patient underwent a left anterolateral thoracotomy, which showed a mass extending from the anterior mediastinum, infiltrating the left upper lobe of lung, phrenic nerve, and pericardium. A left upper lobectomy and resection of the mediastinal mass and lymph nodes were carried out. The pathologic analysis showed it to be a type B3 fusiform-cell thymoma, infiltrating the left upper lobe and 1 peribronchial lymph node. A multidisciplined tumor group decided to observe the patient and followed with thoracic computed tomographic scans every 3 months. After 2 years of follow-up, the patient has no evidence of recurrent disease.
