[Gastric granulocytic sarcoma revealed by a massive digestive hemorrhage].

We report the case of a 37-year-old-man having a chronic myelogenous leukemia, who presented, one month after a splenic acutization, massive gastrointestinal bleeding from ulcerated nodules of the gastric fundus. The histologic examination of one of these nodules showed granulocytic sarcoma. In spite of an endoscopic treatment by sclerotherapy with adrenalined serum, the death occurred during a hemorrhagic recurrence. This observation, which is the third case reported of gastric granulocytic sarcoma during the acutization of a myelogenous chronic leukemia, and the first revealed by fatal gastrointestinal bleeding, shows the particular gravity of gastrointestinal bleeding complicating granulocytic sarcoma.
