Los tumores apendiculares son poco frecuentes, siendo las neoplasias epiteliales y los tumores neuroendocrinos los m\u00e1s comunes. Objetivo: Presentar el caso de una paciente con diagn\u00f3stico de tumor de colisi\u00f3n apendicular que se present\u00f3 como apendicitis aguda. Caso cl\u00ednico: Mujer de 35 a\u00f1os de edad sin antecedentes patol\u00f3gicos que consult\u00f3 por dolor epig\u00e1strico de 24 horas de evoluci\u00f3n, con migraci\u00f3n a fosa il\u00edaca derecha, de tipo continuo. El examen f\u00edsico revel\u00f3 un abdomen blando con defensa en fosa il\u00edaca derecha; el an\u00e1lisis de sangre mostr\u00f3 leucocitosis con neutrofilia y una ecograf\u00eda en favor de apendicitis aguda. Se realiz\u00f3 apendicectom\u00eda mediante incisi\u00f3n de Mc Burney. El estudio anatomopatol\u00f3gico e inmunomarcaci\u00f3n inform\u00f3 neoplasia neuroendocrina bien diferenciada y neoplasia epitelial mucinosa de bajo grado. Se realiz\u00f3 seguimiento con marcadores tumorales postquir\u00fargicos con resultados normales, adem\u00e1s de tomograf\u00eda computada y colonoscopia postquir\u00fargicos normales. Discusi\u00f3n: El tumor de colisi\u00f3n apendicular es muy poco frecuente. Generalmente el diagn\u00f3stico se realiza con el estudio anatomopatol\u00f3gico y plantea grandes desaf\u00edos para el control, ya que no existe consenso de c\u00f3mo realizar el seguimiento postquir\u00fargico Conclusi\u00f3n: Se debe investigar m\u00e1s al respecto para contar con recomendaciones de vigilancia para dicha enfermedad.<\/jats:p>","DOI":"10.31053\/1853.0605.v77.n2.25071","type":"journal-article","created":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T10:57:56Z","timestamp":1592564276000},"page":"113-116","source":"Crossref","is-referenced-by-count":8,"title":["Tumor de colisi\u00f3n apendicular: Neoplasia epitelial mucinosa y tumor neuroendocrino"],"prefix":"10.31053","volume":"77","author":[{"given":"Mario Alberto","family":"Cafaro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Gabriel","family":"Yaryura Montero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agust\u00edn","family":"Bianco","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Laura","family":"Petersen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto Dar\u00edo","family":"C\u00e1rdenas Villa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blanca","family":"Cardozo Dutra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto Miguel","family":"Badra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"12333","published-online":{"date-parts":[[2020,4,7]]},"container-title":["Revista de la Facultad de Ciencias M\u00e9dicas de C\u00f3rdoba"],"original-title":[],"link":[{"URL":"https:\/\/revistas.unc.edu.ar\/index.php\/med\/article\/download\/25071\/29618","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/revistas.unc.edu.ar\/index.php\/med\/article\/download\/25071\/29882","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/revistas.unc.edu.ar\/index.php\/med\/article\/download\/25071\/29882","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T10:57:57Z","timestamp":1592564277000},"score":1,"resource":{"primary":{"URL":"https:\/\/revistas.unc.edu.ar\/index.php\/med\/article\/view\/25071"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,4,7]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2020,5,20]]}},"URL":"https:\/\/doi.org\/10.31053\/1853.0605.v77.n2.25071","relation":{},"ISSN":["1853-0605","0014-6722"],"issn-type":[{"value":"1853-0605","type":"electronic"},{"value":"0014-6722","type":"print"}],"subject":[],"published":{"date-parts":[[2020,4,7]]}}}
