Male Affected by Gastric Malignant Tumor, Gross Anatomy

Description

Frontal transparent rendering situates the stomach in the left upper abdomen beneath the left hemidiaphragm, with the abdominal esophagus entering superiorly at the cardia and the proximal duodenum continuing distally from the pylorus. The lesser curvature tracks superomedially toward the gastroesophageal junction, while the greater curvature sweeps inferolaterally, creating the antrum as it approaches the midline. An irregular, raised mass projects from the gastric wall near the pyloric canal or proximal stomach, deforming the mucosal contour and narrowing the luminal pathway toward the duodenum. The surrounding torso provides clear topographic context for the upper gastrointestinal tract. Gastric carcinoma in the antrum or pylorus commonly presents with early satiety and progressive gastric outlet obstruction, whereas lesions closer to the cardia more often relate to dysphagia at the gastroesophageal junction and can be difficult to distinguish from distal esophageal disease on symptoms alone. Seeing the lesion in relation to the cardia, antrum, and pylorus helps explain why endoscopic biopsies target the edge of an ulcerated mass, and why cross-sectional staging focuses on transmural spread with perigastric nodal disease along the lesser curvature and left gastric artery. Small structure, big consequences. In teaching, this artwork fits upper GI anatomy modules, oncology lectures on gastric adenocarcinoma, and pathology discussions contrasting cardia versus distal stomach tumor behavior. It also supports patient-facing explanations in surgical consent materials for distal gastrectomy, antrectomy, or gastrojejunostomy, where understanding proximal and distal margins relative to the pylorus and gastroesophageal junction matters.
