Primary lymphoma of the cecum: a case report

We report here a case of primary colorectal T-cell lymphoma of the cecum in a 30-year-old man. Patient presented with a history of abdominal pain, fever, vomiting and hematochezia. Clinical examination was unremarkable and colonoscopy showed an ulcerating mass in the colon. A right hemicolectomy with dissection of the paracolic lymph nodes was performed. The final histopathological examination showed a primary T- cell lymphoma of the cecum. Staging didn't show any involvement in any other sites of the body. Primary colon lymphoma is a rare gastrointestinal tumor that represents less than 1% of the gastrointestinal lymphomas. Peripheral T-cell lymphoma represents a relatively small proportion of lymphomas and has a lower prevalence in Western countries. The risk factors, clinical presentation, staging, prognostic factors and treatment modalities of extra-nodal lymphoma are discussed.
