Endogenous, nontraumatic clostridial myonecrosis has a frequent association with colon carcinoma, leukemia, diabetes mellitus, and drug-induced immunosuppression. We present two cases of Clostridium septicum myonecrosis. An 18-year-old girl developed severe abdominal pain on day 7 after hospitalization for cytostatic treatment of acute lymphoblastic leukemia. Blood cultures yielded Clostridium septicum and histopathological exam of muscle tissue showed extended myonecrosis. Eventually the patient recovered with antibiotics and surgical therapy. A 72-year-old diabetic woman was treated as an outpatient with an intramuscular injection of steroidal antiphlogistics for "acute lumbar disc disease". The next morning persistence of hip pain and discoloration of the right thigh caused hospitalization under the suspected diagnosis "fracture of the neck of the femur". Clostridium septicum was cultured from intraoperatively taken swabs. At autopsy, in addition to the gangrene, there was an adenocarcinoma of the cecum, which had not been diagnosed during life.

The objective was to analyze risk factors for veno-occlusive disease of the liver (VOD) after allogeneic bone marrow transplantation. A cohort of 1717 recipients of HLA-identical sibling transplants for leukemia between 1988 and 1990, in 200 transplant teams worldwide, was studied. Patients were scored as having VOD if liver tissue showed typical histologic features or if they had all three of the following: (1) jaundice; (2) hepatomegaly and right upper quadrant abdominal pain; and (3) ascites and/or unexplained weight gain. Patients surviving more than 7 days post-transplant without histologic or any of these clinical features of VOD were classified as not having VOD. Patient-, disease- and transplant-related characteristics of 95 patients with VOD were compared to those of 1514 without VOD. Variables correlated with an increased risk of VOD were: pretransplant conditioning with busulfan and cyclophosphamide compared to total body radiation (relative risk (RR) 2.8; P < 0.0001), pretransplant fungal infection (RR 4.1; P = 0.011), pretransplant Karnofsky performance score < 90% (RR 1.9; P = 0.012), prior liver disease (RR 1.9; P = 0.05) and age > 20 years (RR 1.8; P = 0.05). In patients receiving radiation for conditioning, intravenous immune globulin decreased VOD risk (RR 0.26; P = 0.003). This analysis identifies risk factors for VOD. The data suggest several strategies for modifying transplant regimens to reduce VOD risk and which patients might be suitable subjects for trials of strategies of VOD prevention.

Cases of acalculous cholecystitis in patients with acute leukaemia are rare. Manifestations of the primary disease often mask the acute cholecystitis symptoms. A high index of suspicion and ultrasonographic examination in leukaemic patients with abdominal pain and unexplained fever may allow earlier diagnosis, before the development of complications. We report two cases of acute acalculous cholecystitis during the course of acute leukaemia.

A total of 28 patients with leukemia underwent intensive therapy with megadose chemotherapy and stem cell transplantation. Of 16 patients who had busulfan therapy, 2 developed the clinical syndrome of veno-occlusive disease of the liver (VOD) characterized by progressive abnormalities in liver function, abdominal pain, and ascites. Postmortem findings showed VOD of the central and sublobular hepatic vein. Immunohistochemical analysis using anti-actin and CD34 mAb was employed in an attempt to clarify the process of fibrosis. Actin positive cells had accumulated around the central vein. Ito cell activation might be responsible for secondary fibrosis following endothelial injury. We report autopsy findings and immunohistochemical results.

Paclitaxel, a recently approved antineoplastic agent, is cleared slowly from the peritoneal cavity after i.p. injection, and therefore appears to be promising for intracavitary therapy of malignancies confined to the peritoneal cavity. However the dose-limiting toxicity of Taxol, the clinical formulation of paclitaxel, was severe abdominal pain, likely caused by the excipients (Cremophor EL and ethanol) that are required to overcome low drug solubility. We tested the hypothesis that a liposome-based formulation could modulate paclitaxel toxicity independent of antitumor activity. The dose-dependence of toxicity and antitumor effect of paclitaxel liposomes was evaluated after i.p. administration against i.p. P388 leukemia. Liposomal paclitaxel showed antitumor activity similar to that of free paclitaxel (as Taxol), but was better tolerated by both healthy and tumor-bearing mice.

We report the case of a middle-aged man who presented de novo with abdominal pain and hepatomegaly and was found to have positive serology for hepatitis C and subsequently a primary hepatic lymphoma. An increased incidence of primary hepatocellular cancer is well characterized in both cirrhotic and non-cirrhotic cases of chronic hepatitis C. The relationship between chronic hepatitis C and primary hepatic lymphoma remains obscure. It has been established that hepatitis C can sustain the clonal B-cell expansion that occurs in associated cryoglobulinaemia, and hepatitis C RNA has been detected within extrahepatic lymphoma tissue. Viral aetiologies for lymphoma are well characterized, such as Epstein-Barr virus (EBV) and human T-cell leukaemia virus (HTLV) I and II. Existing models of chronic infection causing lymphoma within the gastrointestinal tract include that of Helicobacter pylori and mucosa-associated lymphoid tumour of the stomach. Given the relatively low frequency of occurrence it may be prudent to perform a retrospective analysis on past cases of primary hepatic lymphoma in order to determine whether or not hepatitis C was present.

Cryptococcus neoformans typically causes an insidious illness with symptoms related to meningitis or to lung involvement. This is the first reported sudden death due to cryptococcosis, which occurred in a child with leukemia that was in remission. The child had suddenly looked seriously ill and cried with abdominal pain and then died within 25 minutes. Disseminated cryptococcal infection of the lungs, heart, and pancreas was an unexpected finding at autopsy. This clinical experience raises the question whether fungal infections should now be considered in immunosuppressed patients who have an apparent septic collapse.

The histologic features of acute graft-versus-host disease (GVHD) of the colon are well documented, but chronic mucosal changes associated with GVHD are poorly described. We report here the clinicopathologic findings from five patients with a history of bone marrow transplantation in which colonoscopic biopsies showed chronic mucosal changes reminiscent of chronic idiopathic inflammatory bowel disease (IBD). The patients ranged in age from 2.5 to 31 years. Bone marrow transplantations were performed for leukemia (3 patients), Hodgkin's disease (1 patient), and metachromatic leukodystrophy (1 patient). Endoscopy was performed because of complaints of abdominal pain and diarrhea in all of the five patients. The mean time after transplantation in which histologic features of chronicity were identified was 5.8 months (range, 3-16 mo). All of the five patients had prior colonic biopsies showing acute GVHD. One patient had a previous episode of cytomegalovirus infection. Chronicity was characterized by mild-to-moderate architectural distortion, ie., villiform surface with crypt branching and atrophy, similar to that seen in chronic idiopathic IBD. The lamina propria was hypocellular, with prominent small blood vessels. Focal fibrosis of the lamina propria was noted. One patient had active cryptitis. Superimposed changes of acute GVHD were mild to absent. None of the patients had a history of IBD before receiving the bone marrow transplant. Changes associated with chronicity can be observed in mucosal biopsy specimens from patients with GVHD. It is uncertain whether these changes are directly caused by GVHD or are the result of superimposed infections. The association of chronic mucosal change in the setting of GVHD with the clinical diagnosis of chronic GVHD needs additional investigation.

Typhlitis or neutropenic enterocolitis is a life-threatening, necrotizing process of the cecum whose incidence is increasing. It is usually encountered in patients with leukemia who have recently undergone chemotherapy. Neutropenic enterocolitis presents as fever, abdominal pain, and diarrhea in neutropenic patients. As the incidence of neutropenic enterocolitis increases, emergency physicians must be aware of this rapidly progressive and potentially fatal disease.

We report a case of adult T-cell leukemia (ATL) with gastric involvement visualized by 111In-chloride scintigraphy. A 55-year-old male patient presented with upper abdominal pain and appetite loss. His barium gastric series showed multiple ulcerating polypoid tumors due to gastric involvement of ATL. These lesions accumulated 111In-chloride and were also avid for 67Ga-citrate. Although the mechanism of 111In-chloride accumulation is unknown, 111In-chloride scintigraphy may be useful in evaluating patients with ATL.
