ABSTRACT
El tracto gastrointestinal es el sitio más frecuente de presentación del linfoma no Hodgkin (LNH) extraganglionar. Sin embargo, los linfomas primarios del tracto gastrointestinal son tumores raros y es mucho más frecuente la afectación de este tracto de manera secundaria en el curso de la enfermedad. Representan del 1% al 4% de los tumores malignos del tracto gastrointestinal, aunque tienen un curso, manejo y pronóstico muy diferente de los adenocarcinomas, por lo que es importante conocerlos y tenerlos en mente como un diagnóstico diferencial posible en el ejercicio clínico diario. Afectan más a los adultos jóvenes, con una mayor frecuencia en hombres (1). Reportamos el caso de una mujer de 47 años de edad con linfoma primario del intestino delgado, diagnosticado luego de múltiples consultas por síntomas abdominales y revisamos la literatura al respecto
The gastrointestinal tract is the most frequent site of non-Hodgkins lymphoma (NH) outside of the lymph nodes themselves. This tract is much more frequently compromised by tumors secondary to primary disease elsewhere in the body than by primary lymphomas of the gastrointestinal tract itself which are rare. They account for only one to four percent of malignant tumors of the gastrointestinal tract. Their development and prognoses are quite different from those of adenocarcinomas, hence their management must differ as well. It is important to understand them and keep them in mind in differential diagnosis in daily clinical practice. Young adults are most frequently affected, and men are more frequently affected than are women. We review the literature and report the case of a 47 year old woman with primary small bowel lymphoma that was diagnosed after several consultations due to abdominal symptoms
