[Plasma-cell granuloma of the mediastinum].

Plasma-cell granuloma of the mediastinum is an unusual non-neoplastic lesion; a case of rare mediastinal localization is reported. Only the histopathological examination leads to a correct diagnosis. Since the possibility of local recurrence has been described, total excision is requested. Video-assisted thoracic surgery technique may be difficult to use in the management of these mediastinal tumors due to adhesions between the mass and the surrounding tissues. Complete open resection is the treatment of choice.
