Lymphome diffus a grandes cellules B primitif du colon transverse Diffuse large B-cell lymphoma of the transverse colon

摘要

Rectocolonic localization of primitive extranodal non-Hodgkin lymphoma remains rare. It accounts for only 10-20% of gastrointestinal lymphomas and 0.2-0.6% of colorectal malignancies. We report the case of a patient aged 84 years who was admitted for exploration of constipation with abdominal pain. Colonoscopy revealed an ulcerated lesion of the transverse colon. Histological examination revealed a diffuse large B-cell lymphoma. The staging was negative. The patient died after three cycles of chemotherapy. Through this observation and the literature review, we discuss the epidemiological and clinical-morphological features and treatment of this rare entity. To cite this journal: Acta Endosc. 42 (2012).
