N\u00f3dulo submucoso (lat. sub<\/em> \u2014 bajo, mucosa<\/em> \u2014 membrana mucosa) es una variante cl\u00ednico-anat\u00f3mica del leiomioma uterino, en la cual la formaci\u00f3n crece centr\u00edpeta (hacia la cavidad uterina), deformando su arquitectura.<\/p>\n\n

Etiolog\u00eda y fisiopatolog\u00eda<\/strong><\/h2>\n\n

Seg\u00fan la clasificaci\u00f3n moderna FIGO (PALM-COEIN), los n\u00f3dulos submucosos se dividen en tres tipos seg\u00fan su relaci\u00f3n con el miometrio:<\/p>\n\n

    \n
  • Tipo 0:<\/strong> El n\u00f3dulo est\u00e1 completamente en la cavidad uterina (en un ped\u00edculo), sin penetrar en el miometrio.<\/li>\n\n\n\n
  • Tipo 1:<\/strong> Menos del 50% del volumen del n\u00f3dulo est\u00e1 sumergido en la pared uterina.<\/li>\n\n\n\n
  • Tipo 2:<\/strong> M\u00e1s del 50% del volumen del n\u00f3dulo est\u00e1 ubicado intramuralmente (en el espesor muscular). El n\u00f3dulo causa expansi\u00f3n de la cavidad uterina, incremento del \u00e1rea de descamaci\u00f3n y isquemia\/ulceraci\u00f3n local del endometrio que lo cubre.<\/li>\n<\/ul>\n\n

    Importancia cl\u00ednica<\/strong><\/h2>\n\n

    La localizaci\u00f3n submucosa es la m\u00e1s cl\u00ednicamente agresiva. Incluso los n\u00f3dulos de di\u00e1metro peque\u00f1o (1\u20132 cm) provocan menorragias<\/strong> profusas con co\u00e1gulos, que conducen a anemia severa, resistente a la terapia. Son caracter\u00edsticas los dolores tipo c\u00f3lico (\u00abnacimiento del n\u00f3dulo miomatoso\u00bb). <\/p>\n\n

    Adem\u00e1s, los n\u00f3dulos submucosos act\u00faan como un anticonceptivo intrauterino: causan inflamaci\u00f3n cr\u00f3nica y previenen mec\u00e1nicamente la implantaci\u00f3n, siendo una causa absoluta de infertilidad uterina.
