ABSTRACT
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.

AIM: Gene rearrangement has an important role in the management of lymphoma. We investigated the rearrangements of B-cell leukaemia/lymphoma 2 (BCL2), BCL6 and Paired homeobox 5 (PAX5) genes in Indonesian follicular lymphoma (FL) patients. METHODS: We examined gene rearrangements using various kinds of polymerase chain reactions (PCRs) on 24 patients' peripheral blood DNA. RESULTS: BCL2 rearrangement was found in 58% (14 of 24 patients), 8 at mbr (major breakpoint region), 2 at mcr (minor cluster region) and 4 at icr (intermediate cluster region), respectively. No rearrangement in BCL6 and PAX5 was detected. There was a significant difference in the incidence of spleen involvement between patients with BCL-2 rearrangement and without it (50% vs. 11%, p=0.04). BCL-2 rearrangement was correlated with spleen involvement (OR=9) and anemia (OR=2.3). CONCLUSION: BCL2 rearrangement in Indonesian FL was higher than previous reports from other Asia countries (58% vs. 48%, respectively). Our method using peripheral blood DNA might be useful for the molecular diagnosis of FL.
