Tumor del estroma extragastrointestinal (EGIST) mesentérico: entidad rara con evolución atípica

Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract. Those GIST arising outside the gastrointestinal tract are called extra-gastrointestinal stromal tumours (EGIST) and share clinical, pathological and molecular features. They are very rare and very little is known about the correct management and prognosis of these neoplasms. The case is presented of a patient with a mesenteric EGIST and an unusual outcome. Its differential diagnosis is difficult, and the need for a multidisciplinary team approach is emphasised.
