Es preciso establecer los diferenciales de la enfermedad, debido a que el diagnostico clinico muestra ser aparentemente sencillo, a menudo es diagnosticado erroneamente como Habronemiasis cutanea, tejido de granulacion exuberante, granuloma piogeno y sarcoide equino, ya que se caracterizan por lesiones similares en forma general, sin embargo, la presencia de kunkers (masas necroticas caseificadas), trayectos fistulosos y secrecion filante fibrinosanguinolentas son inequivocas en la pythiosis [13, 17].
