Primary colorectal lymphoma is a very rare disease entity that accounts for less than 0.2-0.65% of all colon cancers. It is as an extranodal lymphoma of the colon that mainly arises from B cells and primary colorectal lymphoma that arises from T cells is very rare both in Western countries and in Korea. Colonic lymphoma can be classified endoscopically into 5 categories as follows: fungating, ulcerative, infiltrative, ulcerofungating, and ulceroinfiltrative type. The endoscopic features of primary colorectal lymphoma differ according to their cellular origin; about half of B cell lymphomas are fungating type whereas most of T cell lymphomas are of ulcerative or ulceroinfiltrative type. Mass forming primary T cell lymphoma of the colon is extremely rare. Herein, we present a case of primary natural killer like T cell lymphoma of the colon presenting as fungating type with review of literature
