[Extraosseus plasma cell lymphoma with ileal localization].

The paper reports a case of extraosseous plasmacytic lymphoma in an ileal localisation in a patient with multiple myeloma. After having underlined the relative rarity of tumours of the small intestine and their diagnostic and clinical characteristics, the paper describes the case in question. The unique nature of the case depends on the extreme rarity of cases of isolated secondary forms in patients with active systemic pathologies reported in the literature.
