En bloc resection for primary non-Hodgkin's lymphoma of the descending colon with massive extension into the neighboring organs.

A 79-year-old female who was surgically treated and received adjuvant chemotherapy for primary non-Hodgkin's lymphoma of the descending colon with massive extension into the pancreatic tail, spleen, and left kidney is herein reported. The patient had acute colonic obstruction and an urgent laparotomy was performed because endoscopic decompression using a transnasal ileus tube could not be done. We performed a left colectomy with an en bloc resection of the neighboring organs, followed by the creation of an end colostomy. The patient had no major postoperative complications and is well without any recurrence of lymphomas 6 months after surgery.
