Case report: robotic thoracic surgery of posterior mediastinal mass

@#We report a 39-year-old male with accidental findings of posterior mediastinum mass at right superior aspects, located at T2 with close proximity to trachea, superior vena cava, azygus vein, right subclavian artery and oesophagus. Apart from intermittent right shoulder pain, there was no other significant symptom. He opted for conservative management initially, given the benign nature and proximity to important structures. We postulated that robotic approach will be of advantage for this particular case which was successfully performed with uneventful recovery. This case illustrated the advantages of robotic-assisted surgery, compared to conventional VATS in otherwise potentially difficult case to undertake.

Benign metastasizing leiomyoma.

Benign metastasizing leiomyoma (BML) is a rare condition, affecting predominantly reproductive-age females with uterine leiomyomata and is most often associated with multiple benign-appearing smooth muscle tumors in lungs. We report herein a case of a 38-year-old woman who presented with multiple uterine fibroids for which hysterectomy was carried out on her. Postoperatively, she developed left-sided pleural effusion. Computed chest tomography (CT) scan revealed multiple nodules in both lungs and pleurae. Histopathology of one of the pleura-based nodules revealed a neoplasm composed of interlacing fascicles of spindle cells with uniform nuclei. The tumor cells were positive for alpha-smooth muscle actin and negative for CD34 immunohistochemical stain.
