Histology images of moderately differentiated adenocarcinoma.. Notes: H-E staining depicts invasive atypical glands with central necrosis in (A) (original magnification x100) and (B) (original magnification x40). (C) Invasive malignant glands lined by atypical pleomorphic cells with prominent nucleoli and central necrosis can be seen (original magnification x400).. Abbreviation: H-E, hematoxylin and eosin.

Biopsies of the mass in the cavity showed normal gastric mucosa with moderately differentiated adenocarcinoma and mild chronic gastritis (Figure 2).
CT scan of the duplication cyst.. Notes: (Ai and Aii) Axial, (B) sagittal, and (C) coronal scans of the chest, abdomen, and pelvis demonstrated a well-circumscribed, round cystic mass of homogeneous density along the greater curvature of the stomach (arrows), consistent with a duplication cyst. The mass measured 5x4 cm.. Abbreviation: CT, computed tomography.
