ADENOSQUAMOUS CARCINOMA OF THE STOMACH-REPORT OF A CASE-

This paper describes a rare case of giant adenosquamous carcinoma of the stomach which was surgically treated. A 48-year-old man was seen at the hospital because of severe hematemesis. A large elastic-hard tumor (8×10cm) was palpable in the epigastrium. Various imaging procedures showed a large tumor of the pancreatic head invading the stomach, gallbladder, liver, and transverse colon. Carcinoma of the head of the pancreas was most strongly suspected, although icterus had not developed. A deep antral ulcer was revealed by gastroscopy. Pure squamous cell carcinoma was confirmed by histopathologic examinatin of biopsy specimens of the gastric ulcer as performed on two separate occasions. Successful surgical resection was carried out with pancreatoduodenectomy, extended cholecys-tectomy, and partial transverse colectomy. The origin of the exramural hemispheric neoplasm with the diametor of about 10cm deduce macrospically because of its adherence to and invasion of nearby organs. Pathologic examination revealed the diagnosis of adenosquamous carcinoma of the stomach since the mucosa of the pancreas, gallbladder, and common bile duct were intact. The patient had a recurrence within 12 months after the operation. The histogenesis of gastric adenosquamous carcinoma is still controversial the four prevailing theories are discussed in this article.
