Recibi\u00f3 tratamiento quir\u00fargico m\u00e1s quimioterapia y radioterapia complementaria, falleci\u00f3 a los 16 meses. Se realiz\u00f3 una b\u00fasqueda de la literatura en las bases de datos Medline v\u00eda PubMed y Embase, que inclu\u00eda reportes y series de caso de mujeres con diagn\u00f3stico de tumor de colisi\u00f3n del \u00fatero, y se extrajo informaci\u00f3n sobre el diagn\u00f3stico, tratamiento y pron\u00f3stico.

El diagn\u00f3stico histopatol\u00f3gico m\u00e1s frecuente fue el adenocarcinoma endometrioide de endometrio y sarcoma endometrial de alto y bajo grado (47 %). El tratamiento b\u00e1sico fue quir\u00fargico. Cerca del 50 % recibi\u00f3 tratamiento adyuvante con quimioterapia y radioterapia (15 %). La sobrevida a 1 a\u00f1o fue del 75 %.\nConclusiones: en la literatura no se identificaron casos de tumores de colisi\u00f3n de \u00fatero con la histopatolog\u00eda y en la ubicaci\u00f3n del caso presentado. La mortalidad a dos a\u00f1os es cercana al 28 % si se toma en cuenta el caso reportado. Se necesitan m\u00e1s estudios que describan la inmunohistoqu\u00edmica, el tratamiento y el pron\u00f3stico de esta condici\u00f3n.<\/jats:p>","DOI":"10.18597\/rcog.4011","type":"journal-article","created":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T17:55:46Z","timestamp":1697738146000},"page":"225-236","update-policy":"https:\/\/doi.org\/10.18597\/crossmark","source":"Crossref","is-referenced-by-count":3,"title":["Tumor de colisi\u00f3n de \u00fatero.
