Sin duda la pythiosis es una enfermedad que no va a reparar por primera intencion, por el proceso infeccioso y el caracter granulomatoso de la lesion, de modo que siempre es mas agresiva y proliferativa, siendo en ese caso necesaria la cicatrizacion por segunda intencion debida a la perdida excesiva o grave comprometimiento tecidual, presencia de kunkers, trayectos fistulosos y excesivo tejido de granulacion, siendo necesaria la instauracion de un tratamiento medico que ayude en el control de la infeccion del oomiceto y promueva la reparacion tecidual (3).
