[Primary lymphoma of the gastrointestinal tract]

Lymphomas of the gastrointestinal tract are rare tumors with unusual features and few characteristics. Clinical, radiological and endoscopic diagnosis is difficult, because they may be confused with inflammatory or neoplastic forms, especially in primary involvement of the gastrointestinal tract. From 1965 we observed 4 patients with primitive gastrointestinal tract lymphomas. Prognostically important features for GI lymphomas were: stage, site of the primary disease, histological type. Authors report on the clinical findings, diagnostic procedures, surgical treatment and results.
