Key result
Video-assisted thoracoscopic chest wall resection was successfully performed for a 3-cm leiomyosarcoma, though liver and lung metastases were detected 5 years post-surgery.
Why the study?
Chest wall sarcomas account for <20% of all soft tissue sarcomas, with leiomyosarcomas representing only 1-4%, and can mimic schwannoma on preoperative imaging.
Case Report (n=1)
No
A rare case of chest wall leiomyosarcoma mimicking a schwannoma was resected using a video-assisted thoracoscopic approach, highlighting the need to consider malignant tumors in patients with chest wall masses.
May warrant extended surveillance after rare chest wall leiomyosarcoma resection; leaves open optimal protocols.
Chest wall sarcomas account for <20% of all soft tissue sarcomas of which leiomyosarcomas represent only 1-4%. We report a case of thoracic leiomyosarcoma that resembled schwannoma in preoperative image studies. A 79-year-old man presented to our hospital with a chest wall tumor that increased in size over 3 months. Computed tomography of the chest revealed a 3-cm mass arising from the chest wall. Thoracic magnetic resonance imaging showed a solid tumor that was hypo-intense on T1-weighted imaging and iso-intense on T2-weighted imaging. Chest wall resection was performed using a video-assisted thoracoscopic approach after a frozen section examination revealed sarcoma. The histological diagnosis was leiomyosarcoma. Liver and multiple lung metastases were detected 5 years after surgery. Malignant tumors should be considered in any patient with chest wall tumors. The thoracoscopic approach could be an optimal treatment for chest wall tumor.

Yamamoto et al. (2021) conducted a case report in Thoracic leiomyosarcoma (n=1). Video-assisted thoracoscopic chest wall resection was evaluated. Video-assisted thoracoscopic chest wall resection was successfully performed for a 3-cm leiomyosarcoma, though liver and lung metastases were detected 5 years post-surgery.
