A posterior mediastinal mass was found in a 72-year-old man who complained of progressive shortness of breath. Computed tomography of the thorax showed a well-defined, heterogenous mass measuring 9.5 x 4.0 x 3.0 cm, located in the right costovertebral angle. Complete surgical resection was accomplished through a right posterolateral thoracotomy. The final diagnosis was a leiomyomatous hamartoma of the posterior mediastinum. This is an unusual location for this type of tumor, and it has rarely been reported in the literature.
