Abstract
OBJECTIVES: Gastrointestinal lymphoma is the most common type of extranodal non-Hogkin’s lymphoma. The proportion and different types of primary extranodal gastrointestinal non-Hodgkin’s lymphoma are different in various geographic locations. Therefore, in this study we tried to evaluate the various types of extranodal gastrointestinal non-Hodgkin’s lymphoma in affiliated hospitals of the Shiraz University of Medical Sciences as the largest referral center in the southern Iran.
DESIGN: During 5 years (2005 – 2010), the pathology archives and clinical charts of all patients diagnosed with primary gastrointestinal non-Hodgkin’s lymphoma in the affiliated hospitals of the Shiraz University of Medical Sciences were evaluated. All demographic and pathologic findings were recorded.
RESULTS: During these 5 years, there were 110 cases with the diagnosis of primary gastrointestinal lymphoma. The most common location was stomach followed by small intestine and colon. The most common type was diffuse large B cell type. There were only two cases of immunoproliferative small intestinal lymphoma.
CONCLUSION: The pattern of gastrointestinal lymphoma in Iran is very similar to the Western countries. Compared with 40 years ago, it seems that the epidemiology of this lymphoma has changed.
