Immunosuppression for therapeutic reasons (e.g. post transplantation, post chemotherapy), as well as pathologic immunodeficiency due to certain pathologic conditions (e.g. AIDS, leukemia), is increasingly encountered in daily medical practice. As a result, the concomitant risk for opportunistic infections is higher and immunocompromised patients may present with uncommon clinical and radiologic conditions. We report on a case of a 33-year-old immunocompromised woman with a history of recurrent T-cell lymphoblastic lymphoma, which presented with abdominal pain. Computed tomography (CT) images demonstrated significant small bowel dilatation, wall thickening, and high-density intestinal content, with a focal point of transition in the pelvis. Extensive fungal enteritis due to Candida Albicans with partial small bowel obstruction was found on autopsy.

Here we report a 41-year-old woman with the diagnosis of acute myeloid leukemia. While being followed on remission after allogeneic peripheral blood stem cell transplantation, she developed systemic and central nervous system (CNS) relapse. CNS involvement presented first with meningeal irritation signs and then with cauda equina syndrome (CES). We define an interesting presentation of CES as abdominal pain and discuss the rare coexistence of the syndrome and leukemia under the light of the pertinent literature.

We report a rare case of myeloid sarcoma (MS) of the extrahepatic bile ducts presenting as obstructive jaundice in a patient without leukemia at time of diagnosis. A 75-year-old female presented with a one-month history of abdominal pain and jaundice. Computerized tomography scan of the abdomen showed stenosis of the extrahepatic bile ducts. Endoscopic retrograde cholangiography disclosed an irregular narrowing of the common biliary duct, suggestive of a cholangiocarcinoma, and resection was performed. Histologic examination showed diffuse transmural infiltration of malignant cells. These cells exhibited medium-sized round nuclei with central nucleoli and eosinophilic cytoplasm, and were strongly positive for myeloperoxidase, CD68, lysozyme, CD45, CD117 (c-kit protein) and CD43. Eight months following surgery the patient presented with multiple cutaneous nodules and bone marrow trephine biopsy showed acute myelomonocytic leukemia. A literature search identified two previously reported cases of MS of the extrahepatic biliary duct. MS should be taken into consideration in the differential diagnosis of a patient with obstructive jaundice. Immunohistochemistry is essential for a correct diagnosis.

Intestinal barrier function was prospectively examined in the course of a clinical trial evaluating the efficacy and safety of lisofylline for reducing cytotoxic therapy-induced intestinal epithelial damage-related infectious morbidity in patients receiving standard remission-induction therapy for acute myeloid leukaemia. The absorption and permeation of oral D-Xylose, lactulose and mannitol were measured weekly from baseline until marrow recovery in adult recipients of idarubicin plus cytarabine for untreated acute myeloid leukaemia. These studies were correlated with non-haematologic chemotherapy-related toxicities reflecting mucosal damage, including nausea, vomiting, stomatitis, diarrhoea, abdominal pain and systemic infection. D-xylose absorption decreased and lactulose:mannitol ratio reflecting intestinal permeability increased from baseline until the second and third week after the beginning of the treatment followed by recovery. These measures correlated with infection rates, nausea, vomiting, diarrhoea and increased blood product utilization. Lisofylline was associated with increased intestinal permeability, nausea, vomiting and infection-related morbidity despite a reduction in the duration of neutropaenia. These surrogates of intestinal barrier function correlated well with clinically important outcomes despite the failure to demonstrate reduced morbidity with lisofylline and represent useful objective outcome measurements for future clinical trials of products for the amelioration of the effects of cytotoxic therapy on the intestinal mucosa.

Primary gut involvement by Aspergillus is an exceedingly rare and often a fatal complication of intensive chemotherapy in patients with acute leukaemia. We report a 46-yr-old patient with granulocytic sarcoma of the testis. He received acute myeloid leukaemia type treatment with ADE chemotherapy (Cytosine Arabinoside, Daunorubicin and Etoposide). While neutropenic he presented with pyrexia, abdominal pain and massive abdominal distention. He was treated with intravenous antibiotics and antifungals according to our usual institutional protocol without any response. He was found to have toxic megacolon on plain X-ray and subsequently underwent total colectomy and ileostomy. The colon histology showed Aspergillus fungal hyphae infiltrating the bowel wall. There was no any evidence of pulmonary, hepatic, splenic or renal lesions on the computerised tomography scan. Following colectomy, he was treated with 2 wk of antifungal treatment. He recovered well and was discharged home. The increased awareness, high degree of clinical suspicion of unusual presentation and early surgical intervention with aggressive antifungal treatment, has a key role in the management of these rare and often fatal cases.

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.

Arsenic trioxide (ATO) induces remission in 85% of adults with refractory acute promyelocytic leukemia (APL). We conducted a phase 1 trial of ATO in children (median age 13 y, range, 2-19) with refractory leukemia. ATO was administered intravenously over 2 hours, 5 d/wk for 20 doses/cycle. Patients with APL (n=13) received 0.15 mg/kg per day, and patients with other types of leukemia received 0.15 mg/kg per day (n=2) or 0.2 mg/kg per day (n=4). Nineteen of the 24 enrolled patients were fully evaluable for toxicity. At 0.15 mg/kg per day, 2 of 15 patients experienced dose-limiting corrected QT interval (QTc) prolongation, pneumonitis, or neuropathic pain. At 0.2 mg/kg per day, 2 of 4 patients had dose-limiting QTc prolongation or pancreatitis. Non-dose-limiting toxicities included elevated serum transaminases, nausea, vomiting, abdominal pain, constipation, electrolyte imbalance, hyperglycemia, dermatitis, and headache. At 0.15 mg/kg per day, the median (range) plasma arsenic maximum concentration (Cmax) was 0.28 microM (0.11-0.37 microM) and at 0.2 mg/kg per day, Cmax was 0.40 and 0.46 microM; area under the concentration times time curve (AUC0-24) was 2.50 microM-hr (1.28-3.85 microM-hr) and 4.37 microM-hr and 4.69 microM-hr, respectively. Morphologic complete response (CR) was achieved in 85% of patients with APL; no responses were observed in non-APL patients. ATO is well-tolerated in children at the recommended dose of 0.15 mg/kg per day. The response rate in children with relapsed APL is similar to the response rate in adults. This trial was registered as #NCT00020111 at www.ClinicalTrials.gov.

Neutropenic enterocolitis or typhlitis (from the Greek typhlon, meaning caecum) is defined as a necrotizing colitis with inflammation of the cecum and surrounding tissues. Although this condition occurs primarily in severely myelosuppressed and immunosuppressed patients with leukemia, it may also occur in those with other advanced malignancies receiving myelosuppressive chemotherapy. It has been described most recently in patients with solid tumors who receive taxane-based therapy. A 60-year old woman with medullary breast cancer stage IIIB underwent neoadjuvant chemotherapy with TAC (doxetaxele 100 mg/m2, doxorubicin 50 mg/m2 and cyclophosphamide 600 mg/m2). Sixth day after TAC chemotherapy, she had abdominal pain and vomiting. Abdomen CT scan showed diffuse circumferential thickening of ileum wall typical for ileitis, narrowing of the lumen, disturbance of peristaltic. This abdomen CT scan was thought as abnormality pictures of neutropenic enterocolitis. Neutropenic enterocolitis should be considered in patients with abdominal symptoms especially during the granulocyte nadir following chemotherapy. Increased awareness of this rapidly progressive and potentially fatal disease leads to accurate diagnosis and the prompt treatment that can decrease morbidity and mortality.

Differential diagnosis of a focal splenic lesion in the context of acute leukemia is quite challenging. A 58-year-old woman presented with a 3-day history of fever and abdominal pain. The results of hematological work-up were consistent with acute myeloblastic leukemia (M2, French-American-British classification). Being susceptible to infection in this leukemic patient with severe neutropenia, a diagnosis of splenic abscess was straightforward, plausibly supported by the radiographic findings. Despite empiric broad-spectrum antibiotic treatment, hyperleukocytosis with resultant pulmonary leukostasis supervened. Histological sections from ultrasound-guided percutaneous core-needle biopsy of the spleen confirmed the diagnosis of myeloid sarcoma. However, delayed leukemia-targeted therapy, unfortunately, resulted in catastrophic mortality. It should be addressed that, even with the advent of modern imaging modalities, there can be a diagnostic pitfall when managing solitary splenic lesion in acute leukemic patients without histological examination. Early recognition with prompt chemotherapeutic intervention can be life saving.

A 14-year-old female patient attended Bristol Dental Hospital for an oral screening prior to undergoing a bone marrow transplant as treatment for her acute lymphoblastic leukaemia. Maxillofacial radiographs revealed multiple, well-defined, non-corticated radiolucent lesions throughout the vault of her skull and mandible. These radiological features (coupled with the patient's age) would have correlated with a diagnosis of Langerhans cell histiocytosis. However, a previous bone marrow biopsy confirmed that the patient did indeed have acute lymphoblastic leukaemia. The lytic lesions were present throughout her entire skeletal frame and had previously led to episodes of leg and abdominal pain. We feel that this radiological presentation of leukaemia needs to be reported as these features could easily have been confused with other haematological or even malignant conditions.
