J Coll Physicians Surg Pak Jan ;11(7):459-60.

The surgical management of a four years old female child, presented at the Islamic International Medical Complex (IIMC), Islamabad, with three months history of recurrent chest infections and failure to thrive, is discussed. Posterior mediastinal tumor was diagnosed radiologically. Tumor had flimsy attachments with pericardium and thoracic aorta but was densely adherent with lower lobe of left lung. The tumor was completely removed along with a segment of lung. The postoperative recovery was uneventful. The diagnosis of malignant ectomesenchymoma was made on histopathology. The patient is well in follow-up. This is the first reported case of malignant ectomesenchymoma arising within posterior mediastinum.
