[Multiple organ resection for extensive lymphoma in the abdominal cavity]

Extranodal lymphomas are quite rare, and they usually present as non-Hodgkin lymphomas. The most common localization is the gastrointestinal tract, mainly the stomach - primary gastric lymphoma; histologically, diffuse large B-cell lymphoma (DLBCL) is the most frequent type. The diagnosis is established based on endoscopic examination with biopsy of the tumor. It is an aggressive tumor, highly chemosensitive, which is why primary systemic chemotherapy is indicated in early, as well as late, stages of the disease. Surgery is indicated to treat complications such as perforation, bleeding or gastrointestinal obstruction. The authors present the case of a chemoresistant patient with hemodynamically significant bleeding, indicated for surgical revision after unsuccessful endoscopic treatment. Multiple organ resection was performed due to the large size of the tumor in the abdominal cavity.Key words: gastric lymphoma - surgical treatment.
