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 IB); and diffuse large B cell lymphoma of small intestine involving descending colon and bilateral ovaries, with lymph node metastasis (2+/5) (Ann Arbor IIE). The patient recovered well, without any obvious complications and was discharged on post-operative day 7. The patient received six cycles of chemotherapy after operation. She has been doing well with no evidence of recurrence for 13 mo.
Core tip: Synchronous gastric cancer and primary small intestinal lymphoma are extremely rare. Only one such case has been reported in English literature. We here report a case of a 49-year-old woman with synchronous gastric cancer and primary small intestinal lymphoma, who was successfully treated by combined laparoscopic resection and adjuvant chemotherapy.
