[Amebic colitis and liver abscess complicated by high serum procalcitonin in acute myeloid leukemia].

We present a case of amebic colitis and liver abscess complicated by acute myeloid leukemia (AML) with high serum procalcitonin (PCT). A 61-year-old Japanese man seen at our hospital for severe diarrhea and high fever was found to have multiple ulcers in the transverse and sigmoid colon and rectum by colonoscopy and biopsies were conducted. Immature leukocytes with mild anemia and thrombocytopenia were seen in peripheral blood, necessitating bone marrow aspiration and biopsy that yielded a diagnosis of AML (FAB M4Eo).
