Intestinal Stromal Tumor Coexisted With Acute Promyelocytic Leukemia: A Case Report

Lower gastrointestinal hemorrhage is a nonspecific common symptom of both acute promyelocytic leukemia (APL) and gastrointestinal stromal tumors (GIST). The possibility of GISTs is rarely considered in patients with APL when intestinal hemorrhage occurres. We treated a case of GISTs coexisting with APL in July 2006. The diagnosis of GIST was verified through surgery and pathological examination of the resected intestinal mass.
