| Abstract: | A 17-month-old female was first admitted to our hospital at 7 months of age because of an anterior mediastinal mass associated with mild respiratory symptoms. She underwent a biopsy of the mass that disclosed benign thymic hyperplasia. She came back 8 months later with a larger mass of the mediastinum obstructing the airway. She was intubated and underwent excision of the mass; the histological diagnosis was malignant mesenchymoma. From this experience, it is suggested that more aggressive follow-up, including repeated biopsy, must be considered for a persistent large thymic mass.Offprint requests to: T. Muraji |
