Abstract:
A 62-year-old man was admitted for the evaluation of epigastric pain. Upper gastrointestinal endoscopy revealed a type 3 circumferential carcinoma in the gastric antrum. Distal gastrectomy was performed, and the lesion was histopathologically diagnosed as gastric cancer with an invasive micropapillary carcinoma component. Chemotherapy was administered after surgery; however, he died with multiple liver metastases after 39 months. Micropapillary carcinoma is a rare, high-grade, malignant histological subtype of gastric cancer that has not been described in detail till date. Here we describe this rare lesion and present a review of the relevant literature.
