[A case of primary adenosquamous carcinoma of the stomach preoperatively diagnosed by endoscopic biopsy].
A 53-year-old complained of upper abdominal pain. A diagnosis of Borrmann III type gastric cancer in the posterior part of the corpus region was made by X-ray and endoscopy, and primary adenosquamous carcinoma was preoperatively diagnosed by endoscopic biopsy. Subtotal gastrectomy was performed. The part of the adenocarcinoma adjacent to squamous-cell carcinoma was poorly differentiated. Adenosquamous carcinoma of the stomach is rare. Furthermore, preoperative diagnosis by endoscopic biopsy is extremely unusual, having been reported in 7 cases in Japan including ours. And in 5 cases out of 6, region of the adenocarcinoma was the poorly differentiated type.
