Jejunal Perforation Caused by Primary Jejunal Diffuse Large B Cell Lymphoma

ABSTRACT

Small bowel malignancy accounts for approximately 2% of gastrointestinal malignancies. In particular, malignant lymphoma of the small intestine is so rare that it accounts for less than 1% of gastrointestinal malignancies. Initial symptoms are non-specific and diagnosis may be delayed until the patient presents with complications such as intestinal obstruction, hemorrhage, or perforation. A 79-year-old man visited the emergency room with lower abdominal pain. Segmental resection of the small intestine was done and surgery revealed a 9.5x6 cm sized mass with jejunal perforation at 20 cm inferior to the ligament of Treitz. The mass was diagnosed as diffuse large B cell lymphoma. We experienced a case of diffuse large B cell lymphoma which was diagnosed after emergent surgery for jejunal perforation, and report it with a review of literature.
