title: [Granular cell myoblastoma localized in the thoracic wall].
abstract: We report the case or a 40-year-old man with a large right parasternal tumor. Computerized tomography (CT) and magnetic resonance (MR) imaging showed a soft tissue mass infiltrating contiguous structures with no sign of adenopathy and with disease limited the chest wall. The histological type was granular cell tumor (GCT) with discrete cell pleomorphism and nuclei that varied in form and size, with prominent nucleoli. Eighteen months after surgery, the patient was asymptomatic and disease free. GCT is a rare entity that is uncommonly found on the chest wall. A diagnosis of malignancy is established when metastasis is found to be of the same histological type as that of the primitive tumor. Neither cell pleomorphism or nuclei with nucleoli allows for a diagnosis of malignancy; only a size greater than 5 cm and locally invasive behavior should lead to an assumption that these tumors are of unspecified malignancy. We believe the treatment of choice for these lesions is radical removal
