PALOMARES-CAPETILLO, Paola; ARMAS-ZARATE, Francisco Javier  and  INIGUEZ-GARCIA, Marco Antonio. Schwannoma, a differential diagnosis in posterior mediastinal tumors. Neumol. cir. torax [online]. 2022, vol.81, n.4, pp.256-259.  Epub Feb 19, 2024. ISSN 0028-3746.  https://doi.org/10.35366/112956.

Tumors of the posterior mediastinum are predominantly neurogenic tumors. Neurogenic tumors arise from tissues whose origin is the embryonic neural crest, and are classified according to whether they grow from the nerve sheath, nerve cells or are paraganglionic. Among the group of benign nerve sheath tumors, schwannomas and neurofibromas are the most common. Schwannoma is the most frequent intrathoracic neurogenic tumor. The cornerstone of treatment of neurogenic tumors, whether benign or malignant, is complete surgical resection, and is important for diagnostic confirmation and to prevent malignant degeneration.

Keywords : posterior mediastinum; tumor; schwannoma.
