Resumen

Los tumores estromales forman parte, junto con leiomiomas y schwanomas, de los denominados tumores mesenquimatosos de la pared intestinal. El tumor estromal se diferencia histológicamente de los demás tumores mesenquimatosos al derivar de las células intersticiales de Cajal.

Estos tumores pueden localizarse a lo largo de todo el tubo digesti-vo, aunque son más frecuentes en estómago e intestino delgado. Clínicamente se manifiestan como una anemia secundaria a un sangra-do intestinal. Son raros los cuadros abdominales agudos por perfora-ción o necrosis.

Presentamos el caso de un tumor estromal yeyunal con necrosis ma-siva liquefactiva, lo cual le confiere unas características radiológicas peculiares.

Abstract

Stromal tumors, together with leiomyomas and schwannomas, constitute the so-called mesenchymal tumors of the intestinal wall. Stromal tumors are histologically differentiated from other mesenchymal tumors in that they are derived from the interstitial cell of Cajal.

These tumors can be encountered at any point throughout the entire digestive tract, but usually develop in stomach or small bowel. The clinical presentation in anemia secondary to gastrointestinal bleeding. Acute abdomen due to perforation or necrosis is rare.

We present a case of jejunal stromal tumor with massive liquefaction necrosis, a circumstance that resulted in the peculiar radiological features observed.

Key word:
Stromal tumors
Gastrointestinal stromal tumor
Gastrointestinal mesenchymal tumor
