Bottom Line: Primary gastric adenosquamous carcinoma is a rare malignancy, mostly associated with Asian populations.Adenosquamous gastric cancer is a rare diagnosis in western populations.The hypothesis that a particular histological type of gastric cancer may arise from stem cells might be a field of research in oncological disease of the stomach.

ABSTRACT

Introduction: Most gastric tumors are adenocarcinomas. Primary gastric adenosquamous carcinoma is a rare malignancy, mostly associated with Asian populations. It constitutes less than one percent of all gastric carcinomas and its clinical presentation is the same as adenocarcinoma. It occurs more frequently in the proximal stomach, usually presents with muscular layer invasion and tends to be found in advanced stages at diagnosis, with a worse prognosis than adenocarcinoma.

Case presentation: We report the case of an 84-year-old Caucasian woman with an adenosquamous carcinoma extending to her serosa with lymphatic and venous invasion (T3N1M1). Nodal and hepatic metastasis presented with both cellular types, with dominance of the squamous component.

Conclusions: Adenosquamous gastric cancer is a rare diagnosis in western populations. We present the case of a woman with a very aggressive adenosquamous carcinoma with a preponderance of squamous cell component in the metastasis. Several origins have been proposed for this kind of carcinoma; either evolution from adenocarcinoma de-differentiation or stem cell origin might be possible. The hypothesis that a particular histological type of gastric cancer may arise from stem cells might be a field of research in oncological disease of the stomach.

Figure 1: Intra-operative - dissection from the liver surface.

Mentions: The upper gastrointestinal series was consistent with a mass in the antrum and the abdominal computed tomography (CT) scan revealed a thickening of her gastric wall and a mass without a clear interface with her liver. She underwent a sub-total distal gastrectomy with a Billroth type-2 anastomosis. Intra-operatively, she was found to have a perforated mass with extraluminal growth and adherent to the liver (Figure 1), which led to a resection of the liver parenchyma adjacent to the tumor. In the post-operative period, she developed systemic inflammatory response syndrome (SIRS) with multiple organ failure and died on the 23rd post-operative day.
