Coexistence Hodgkin's lymphoma and colonic adenocarcinoma: a case report.

We present the case of a patient having colonic adenocarcinoma and also incidentally found Hodgkin's lymphoma which involved a single mesenteric lymph node dissected from the sigmoidal resection performed for colonic carcinoma. The disease was confirmed with the removal of right posterior cervical lymph node. Coexistence of colonic carcinoma and lymphoma in the same patient is an uncommon event.
