[Cutaneous lymphomas : Clinical presentation - diagnosis - treatment]

Two secondary localisation of non-Hodgkin's lymphomas in the upper gastrointestinal tract

Extranodal non-Hodgkin's lymphomas of the gastrointestinal tract represent 30%-40% of all extranodal lymphomas. Gastric lymphomas are increasingly described in the literature due to the development of diagnostic techniques and the increased incidence, together with the reduced incidence of gastric solid neoplasms. Significant diagnostic difficulties are determined by the non-specificity of the symptoms, which are mostly chronic, characterised by a slow progression. Localisation in the small intestine often appears as surgical urgency, due to the development of an intestinal obstruction or enterorrhagia. We present two cases of extranodal diffuse large B-cell lymphoma localisation, presented as a secondary lesion localised in the first one in the stomach, and in the second one in the first duodenal portion.
