Tumores extramucosos de colon: diagnóstico diferencial

espanolLos tumores estromales o mesenquimaticos derivan de la pared extramucosa del tubo digestivo y constituyen un grupo raro de tumores originados del tejido conectivo. Presentamos dos casos clinicos, en lo que la sospecha diagnostica inicial era GIST pero tras intervencion quirurgica y resultado anatomo-patologico se evidencio la existencia de tumor fibroso solitario y lipoma, descartando por tanto la existencia de GIST. Es fundamental, por tanto, llevar a cabo un diagnostico diferencial de estos tumores extramucosos ya que el tratamiento y el seguimiento dependeran de la entidad. EnglishMesenchymal or stromal tumors derived from extramucosal gut wall and are a rare group of tumors caused connective tissue. We present two cases in which the initial diagnostic suspicion was but after GIST surgery and anatomy-pathological result was evidence of solitary fibrous tumor and lipoma, thus ruling out the existence of GIST. It is essential therefore to carry out a differential diagnosis of these tumors extramucosal as treatment and monitoring depend on the entity.
