Primary Gastric Localization of Diffuse Large Cell Lymphoma and Viral Hepatitis C. A Case Report at the Department of Clinical Hematology of University Hospital of Yopougon, Abidjan (Côte d’Ivoire)
Non-Hodgkin's lymphomas are characterized by its clinical and pathological polymorphism. In the stomach, MALT lymphomas are common and mostly associated with Helicobacter Pylori infection. We report a case of 76-year old women with a medical history of chronic stomach pain, addressed for the investigation of normochromic normocytic anemia. The clinical picture included signs of digestive hemorrhage and stomach pain. Gastrointestinal endoscopy and histology noted an unspecified ulcer-budding tumor without signs of Helibacter pylori infection. Immunohistochemistry concluded to diffuse large B cell lymphoma with CD79b +, BCL10 +/-, BCL2+, BCL6 +, MUM1+. The Ann Arbor classification was stage IE. The serology of Helicobacter pylori was negative. Pre-treatment investigation noted a comorbity with Hepatitis C infection. This study has two interests. Firstly the rarity of the localization of this lymphoma, and secondly, the etiopathological interest because of association with hepatitis C virus.
