Uncommon trans-iliac bone faecal fistula in a leukaemic patient.

This is a rare case of an elderly woman diagnosed with acute myeloid leukaemia secondary to myelodysplastic syndrome who presented a spontaneous trans-iliac bone faecal fistula probably related to an incarcerated inguinal hernia and neutropaenia. As far as we know, this is the first described case of a trans-iliac bone faecal fistula.
