Gastroblastoma in Adulthood—A Rarity among Rare Cancers—A Case Report and Review of the Literature

Figure 1

Gastroblastoma is a biphasic epithelial and mesenchymal tumor. Epithelial cells were characterized by round uniform nuclei, slightly eosinophilic cytoplasm, and inconspicuous nucleoli, are arranged also in glands or rosette-like structures containing luminal eosinophilic secretory material (a) and they showed strong pan-cytokeratin staining (d). Mesenchymal areas are organized in spindle cell fascicles (b) showing clear staining for vimentin (insert b). Necrosis is well represented (c). According to the biphasic nature of this neoplasm vimentin and CD10 are also expressed in epithelial glandular component (e–f). (Magnification 200x, scale bars 50 µm.)
