Laparoscopic resection of synchronous gastric cancer and primary small intestinal lymphoma: A case report

Synchronous gastric cancer and primary small intestinal lymphoma are extremely rare. A 49-year-old woman was referred to our hospital with a history of upper abdominal pain for two weeks and was diagnosed with synchronous cancer. During hospitalization, the patient underwent laparoscopic distal gastrectomy + resection of bilateral ovaries + partial resection of both small intestine and descending colon. Pathological examination revealed a synchronous cancer consisting of early gastric cancer with poorly differentiated adenocarcinoma located in mucosa, with lymph node metastasis (3+/29) (T1N1M0, stage. B); and diffuse large B cell lymphoma of small intestine involving descending colon and bilateral ovaries, with lymph node metastasis (2+/5) (Ann Arbor. E). The patient recovered well, without any obvious complications and was discharged on postoperative day 7. The patient received six cycles of chemotherapy after operation. She has been doing well with no evidence of recurrence for 13 mo. (C) 2014 Baishideng Publishing Group Inc. All rights reserved.
