Representative images of radiology, histology, immunostaining as well as results of array-comparative genomic hybridization (array-CGH). A: Chest X ray showed mediastinal widening. B: chest CT scan revealed anterior mediastinal mass that invade pericardium. C: tumoral sheets and glandular structures in desmoplasticstroma (H&E stain, × 400). D: Malignant glands showed diffuse membranous positivity for CD5. (Immunoperoxidase). E: nuclear positivity for CDX-2 in malignant glands (Immunoperoxidase). F: Malignant glands showed diffuse positivity for CK20 (Immunoperoxidase). G: benign columnar linningthymic cyst adjacent to neoplastic glands (H&E stain, × 200). H: neoplastic glands arising in the vicinity of thymic cyst (H&E stain, × 200). I: Array-CGH-results displayed in a whole genome view showed deletion of chromosome 6. J: Homozygously deleted region around the HLA-DRB5-locus in chromosomal region 6p21.32.
