RESUMEN
Factor VII is a new coagulation factor replacement therapy. It has permitted the practice of invasive procedures which were up until recently associated with a huge risk of bleeding in patients with hemophilia with inhibitors. Our case illustrates factor replacement therapy failure in a 13-year-old child operated on for hepatic cysts associated with a pelvic cyst. Major bleeding occurred postoperatively requiring several transfusions, an increase in dosage of factor VII, and administration of a heavy dose of factor VIII as a last resort. This case highlights the possibility of failure of factor replacement therapies constituting a life-threatening situation in which alternatives are few.

Leech infestation occurs after swimming or ingestion of freshwater, especially in rural areas. Symptoms are different depending on the binding site of the leech. At the nasopharynx, it is mainly responsible for epistaxis. We report a case of an unknown pharyngeal location of a leech in a three year-old girl responsible for melena and leading to a severe anaemia.
