Posterior mediastinal myelolipoma resected by video-assisted thoracic surgery

Myelolipoma (ML) is a benign tumour composed of haematopoietic and mature adipose tissue commonly found in adrenal glands. Prognosis is usually good with an indolent clinical course. The occurrence of an ML in the extra-adrenal site is very rare. Herein, we report a very interesting and unusual case of ML located in the posterior mediastinum successfully resected by video-assisted thoracic surgery. The clinical and histological features are largely discussed.
