Primary rectal lymphoma: unusual treatment for a rare case

Abstract

Primary gastrointestinal lymphomas account for 5 % of all lymphomas. Lymphomas could be seen through gastrointestinal tract from oral cavity to rectum. Rectum is fairly uncommon site for lymphoma compared to other gastrointestinal sites. Primary rectal lymphomas (PRL) are the most rarely disorder accounting for 0.05 % of all colonic malignancies and 0.1-0.6 % of primary rectal tumors. It is unclear whether surgery or combination or alone chemo/radiotherapy improves the prognosis and survival in such patients. The role of surgery in PRL of the rectum is still controversial. Therefore we want to present a case, provided complete remission treated with combination chemo / radiotherapy without any operation.
