Synchronous tumors: Hodgkin disease presenting in mesenteric lymph nodes from a right hemicolectomy for colon carcinoma.

The authors report the case of a 56-year-old male diagnosed with Hodgkin disease involving the mesenteric lymph nodes recovered from a right hemicolectomy for colonic adenocarcinoma. The liver and bone marrow were also involved by Hodgkin disease. Synchronous colonic carcinoma and lymphoma in the same patient is a rare occurrence, and Hodgkin disease involving the mesenteric lymph nodes is uncommon as well.
