TY - JOUR T1 - Malignant gastric lymphoma with spontaneous perforation JF - BMJ Case Reports DO - 10.1136/bcr.05.2011.4251 VL - 2013 SP - bcr0520114251 AU - Satoko Shimada AU - Tokichi Gen AU - Hiroyuki Okamoto Y1 - 2013/01/17 UR - http://casereports.bmj.com/content/2013/bcr.05.2011.4251.abstract N2 - Malignant gastric lymphoma, accounting only for 1% of primary gastric carcinoma, is usually a diffuse large B-cell lymphoma. Toyota et al reported that 37% of gastric perforations involved malignancy, generally gastric carcinoma. Fukuda et al found that less than 5% of malignant gastric lymphomas perforate. While it is relatively well known that perforations often take place during chemotherapy, they are rare in patients not receiving chemotherapy. To our knowledge, spontaneous perforation is rare in gastric malignant lymphoma, having been reported in the Japanese literature only 26 times, including this case, in the last 25 years. ER -
