Computer tomography (CT) of the abdomen and pelvis showed a large heterogeneous mass involving the posterior gastric wall with diffuse extension into the gastric cardia. Two irregular hypodensities measuring 1.1 cm and 1.3 cm were identified in the inferior left hepatic lobe.

Two irregular hypodensities measuring 1.1 cm and 1.3 cm were identified in the inferior left hepatic lobe (Figure 1).
Esophagogastroduodenoscopy (EGD) revealed a large fungating mass in the lesser curvature of the stomach.

Esophagogastroduodenoscopy (EGD) revealed a large fungating mass in the lesser curvature of the stomach (Figure 2).
Biopsy of the mass revealed small-cell carcinoma of the stomach.

Biopsy of the mass revealed small-cell carcinoma of the stomach (Figure 3) with chronic active Helicobacter pylori gastritis.
Staging positron emission tomography/computer tomography (PET/CT) of the chest, abdomen, and pelvis revealed fludeoxyglucose (FDG) uptake along the gastric lumen with maximum standardized uptake value (SUV) of 6.5 and increased uptake along the mesentery and cecum with maximum SUV of 5.6 and 5.8, respectively.

S100. Staging positron emission tomography/computer tomography (PET/CT) of the chest, abdomen, and pelvis revealed fludeoxyglucose (FDG) uptake along the gastric lumen with maximum standardized uptake value (SUV) of 6.5 and increased uptake along the mesentery and cecum with maximum SUV of 5.6 and 5.8, respectively (Figure 4). 
Seven months after initial presentation, a repeat CT of the abdomen showed progression of extensive metastatic disease, numerous hepatic metastases, ascites, and bilateral pleural effusions.
