A 71-year-old man was admitted to our hospital because of right lower abdominal pain. He was suspected of having acute appendicitis and soon after admission, appendectomy was performed. Macroscopically, the appendix was greatly swollen and reddened, but had no abscess. Microscopically, polymorphonuclear leukocytes were not found, but diffuse infiltration of atypical cells was observed. Examination of a bone marrow aspirate revealed 74% blasts that were peroxidase stain positive. We diagnosed acute myelogenous leukemia (FAB classification, M2). He received induction chemotherapy, but died 49 days after admission. Leukemic cell infiltration of the appendix is rare and acute appendicitis as the initial manifestation of leukemia is even rarer.

In this report we focus on the importance of an accurate diagnosis of gastrointestinal complications during chemotherapy for acute myeloid leukemia. The leukemic infiltrtion of the digestive system may cause mucosal ulcers which can lead to bleeding or perforation. The immune system deficiency in this cohort of patients may result in necrotic enterocolitis (leukemic typhlitis), perianal inflammation, abscesses, and peritonitis. We describe a 37-year old male who presented in June 2004 with 2-month history of fever, weakness and sore throat, treated with antibiotic therapy. Physical examination demonstrated palor. The peripheral blood count at admittance was as follow: Hemoglobin 87 g/l, WBC 63 x 10(9)/l, and platelets 56 x 10(9)/l. The peripheral blood differential count showed: myeloblasts 4%, polymorphonuclear neutrophils (PMN) 20%, monocytes 60%, lymphocytes 16%. The diagnosis of acute myeloid leukemia (AML) was confirmed by bone marrow aspirate, which presented an almost total infiltration by monocytoid blasts, AML type M5 according to FAB classification. Immunophenotypic evaluation by flow cytometry showed that the blast cells reacted with antibodies to CD33, CD13, CD14, CD64, CD15, cytogenetics showed normal karyotype. Induction treatment consisting of cytarabine 2 x 200 mg intravenously in push on days 1-8, vepeside 200 mg i.v. on days 1-5, adriblastine 90 mgon days 1,3 and 5. On day 15 of chemotherapy the patient got fever 38.5 degrees C, abdominal pain and diarrhea (10 stools daily). Broad-spectrum antibiotic therapy with ceftriaxone and amikacin was promptly instituted but condition worsened, abdominal pain extended to all abdomen while the fever and diarrhea persisted. Ultrasonography on day 18 documented bowel wall thickness of colic tract, part of duodenum and jejunum. Owing to suspicion of neutropenic enterocolitis, antibiotic therapy intensified with teicoplanin, fluconazole, metronidazole and pipril. Patient was neutropenic and thrombocytopenic, although daily platelet transfusion from a single donor were given. We started with granulocyte colony stimulating factor (G-CSF) 5 g/kg, which was adiminstered for 7 days. After 7 days neutrophil value reached 1 x 10(9)/l, but fever persisted, abdominal distension and diarrhea progressively improved. The fever peristed and central venous catheter was removed on day 30. After removal of the catheter the patient was getting better: the fever disappeared. The blood count showed Hb 91 g/l, WBC 3,4 x 10(9)/l, platelet 114 x 10(9)/l and normal leukocyte differential count. We emphesize the importance of collaboration between the hematologist and the surgeon in monitoring gastrointestinal complications during and after chemotherapy for acute leukemias and value of abdominal ultrasonography evaluation.

We report here on the clinical courses of three cases of acute appendicitis during a period of myelosuppression after chemotherapy for acute leukemia. The patients were two boys and one girl with a mean age 11 years (range, 10-12). Two of the patients had acute myeloid leukemia (AML) in subtypes M1 and M2, while the third had acute lymphoblostic leukemia of subtype L1 (FAB classification). All patients had clinical features of fever, abdominal pain, and elevations of C-reactive protein. However, the typical peritoneal signs were blunted and developed transiently in two cases. All patients were diagnosed as having appendicitis with abdominal computed tomography scan (CT), and proceeded to appendectomy. With perioperative support utilizing antibiotics, antifungal agents, blood components, and granulocyte-colony stimulating factor, surgical intervention was successfully performed, and all patients were able to undergo chemotherapy courses shortly after surgery. Histological examinations of the appendectomy specimens showed infiltration of most of the lymphoid cells and a few neutrophils in the wall of the appendix. Enhanced CT was useful in diagnosing appendicitis, which needs to be considered in cases presenting with clinical symptoms such as described here. Because of a high mortality rate after appendix perforation, immediate surgical intervention with sufficient perioperative support should be performed.

Spontaneous remissions of acute myeloid leukemia (AML) have been reported in association with infection. Here, we report a case of spontaneous remission of AML in a 47-year-old Saudi Arabian male patient who presented with a few weeks history of recurrent abdominal pain, vomiting and fever. He was diagnosed with acute monocytic leukemia (AML, FAB M5b) and a perforated bowel. He also had Clostridium septicum bacteremia and thus chemotherapy was deferred. He received supportive therapy and intravenous antibiotics. Six weeks later, he achieved spontaneous and complete remission lasting for about 4 months. The remission and relapse were documented by bone marrow examination. Similarly, previous reports of spontaneous remission of AML were short lived and were followed by relapse and progression.

Granulocytic sarcoma is an uncommon and localized extramedullary tumor composed of immature granulocytic cells. It may present in association with acute myeloid leukaemia, myelodysplastic syndrome and chronic myelogenous leukaemia. Granulocytic sarcoma may occur in any anatomical site but involvement of the gastrointestinal tract is rare, especially in the rectum. We report on the case of a 17 year old female who presented with rectal bleeding, abdominal pain and weight loss one mo prior to admission. Rectosigmoidoscopy revealed a rectal polypoid and ulcerated mass. The histological examination of the mass showed granulocytic sarcoma. Bone marrow examination was compatible with acute promyelocytic leukaemia (FAB type M3). This case report is a reminder of this peculiar sign of tumoral syndrome in acute myeloid leukaemia. We also discuss diagnostic methods and analyze the disease course.
