Myeloid sarcoma is known to precede the development of acute myeloid leukemia (AML) and can be the only clinical manifestation. Gastrointestinal involvement by AML is rare with the commonest site being small intestine. Patients present with vague abdominal pain and/or obstruction. Prognosis is usually poor as most of them rapidly progress to AML. We report a case of 25-year-old man with complaints of abdominal pain and vomiting of one-year duration. OGD scopy revealed infiltration of lesser curvature of stomach. Subsequently patient came back within a week with signs and symptoms of acute intestinal obstruction for which an ileal resection was done. Although the histology of stomach biopsy and ileal segments showing similar features were thought to be non-Hodgkin's lymphoma, immunohistochemistry confirmed the diagnosis of myeloid sarcoma. Bone marrow investigations confirmed involvement by AML. Patient succumbed to the disease due to extensive involvement of AML. This case highlights the primary gastrointestinal manifestation of AML which can often prove to be a diagnostic difficulty clinically and histologically. Prompt diagnosis is essential to hasten the management.

Pyothorax-associated lymphoma (PAL) is a unique and rare non-Hodgkin's lymphoma developing in the pleural cavity following a long-standing history of chronic pyothorax (CP). The development of F-18 2'-deoxy-2fluoro-D-glucose (FDG) positron emission tomography combined with computed tomography (PET/CT) has contributed to the evaluation of lymphoma staging. However, only a few studies describing FDG-PET/CT findings in PAL have been published. This study reported three cases of PAL; all 3 patients had previously undergone artificial collapse therapy for pulmonary tuberculosis. Both the first case (an 84-year-old male) and second case (an 83-year-old male) complained of abdominal pain. An ultrasound scan revealed a mass shadow in the left chest wall without abnormal findings in the abdomen, and the CT and magnetic resonance imaging scans suggested malignant lymphoma of the left chest. FDG-PET/CT imaging showed extremely intense FDG uptake only in the left pleura and chest wall. Diagnosis was CP in the two patients, showing a high maximum standardized uptake value (SUVmax: early, 14.8 and delayed, 19.4 in the first case; early, 20.8 and delayed, 27.3 in the second case, respectively). Histopathological analysis of the specimens obtained by biopsy of the PET/CT-positive pleural mass showed non-Hodgkin's, diffuse large B cell lymphoma in the two cases. The third case was a 79-year-old male with relapse after right pleuropneumonectomy for PAL (diffuse large B cell lymphoma) 4 years earlier. PET/CT showed intense FDG uptake (SUVmax: early, 19.9 and delayed, 35.7) in the right pleura and chest wall. Diagnosis was CP, suggesting the recurrence of PAL. Furthermore, abnormal intense FDG uptake was noted in the hilar, mediastinal and supraclavicular lymph nodes, as well as in the spleen. In conclusion, FDG-PET/CT imaging is useful in the evaluation of the area of invasion in PAL.

The occurrence of adult intussusception from small intestinal lymphoma is quite rare. We present an 82-year-old man with a two-month history of intermittent abdominal pain, nausea and fatigue. Clinical symptoms included moderate abdominal tenderness in the right lower abdomen. Computed tomography scan of the abdomen revealed a mass in the terminal ileum with the sign of "bowel within bowel" which was suspicious of ileo-ileum intussusception. The patient underwent laparoscopic segmental ileal resection. Pathologic evaluation revealed a diffuse large B cell non-Hodgkin's lymphoma of the ileum. The postoperative course was uneventful.

Here we report a case of a 59-year-old man who developed neutropenic enterocolitis(NE)after autologous peripheral blood stem cell transplantation for non-Hodgkin's lymphoma in his second complete remission.Four days after transplantation, the patient suffered from diarrhea, abdominal pain, fever, and paralytic ileus.Abdominal computerized tomography scan revealed bowel wall thickening consistent with NE.Owing to his poor performance status, only medical management, including antibiotics and bowel rest, was administered, and the patient died 18 days after transplantation.Although NE after autologous peripheral blood stem cell transplantation is a relatively rare complication, it is important to be aware that this condition can occur as one of the early complications in stem cell transplantation.

Primary ovarian lymphoma is rare. To better understand the clinicopathological and molecular features of these tumours, we studied 14 patients (age range 13 to 74 years, mean 46.9 years) with non-Hodgkin's lymphoma who initially presented with an ovarian tumour. The clinicopathological features were reviewed and tissue samples were studied by immunohistochemistry and for immunoglobulin gene rearrangement, presence of Epstein Barr virus and for MYC and BCL-2 rearrangements by fluorescence in situ hybridisation. The most common symptoms were abdominal pain and abdominal distension. Ten patients had a unilateral (7 left, 3 right) ovarian mass and 4 had bilateral ovarian masses, size range 4 to 13 cm (mean, 7.9 cm). Of the 14 lymphomas, 12 were classified as diffuse large B-cell lymphoma (DLBCL) and 2 as Burkitt lymphoma. The Burkitt lymphomas had a MYC rearrangement. The DLBCLs were of the germinal centre B-cell-like subtype. One DLBCL patient had MYC and BCL2 rearrangements. The treatment consisted of various combinations of surgery, chemotherapy and radiotherapy. The follow-up period ranged from 3 to 56 months. During the follow-up period, 8 patients died of disease, 4 were alive with disease, and 2 were alive without disease. Most primary ovarian lymphomas are of germinal centre B-cell-like subtype DLBCL, which have high proliferative activity and poor prognosis.

Introduction: Primary intestinal lymphoma (PIL) is defined as an extranodal lymphoma arising in the intestine. This study includes 11 PILs. Objectives: The objective of this study was to evaluate the clinicopathological characteristics of primary non-Hodgkin's lymphoma (NHL) in the small and large intestine. All cases were reclassified according to the World Health Organization classification of lymphoma in 2001. Immunohistochemistry (IHC) was used to confirm the histopathological diagnosis. Materials and Methods: Eleven cases of primary non-Hodgkin in the small and large intestine were studied retrospectively in a 5 year period. There were seven cases of resected intestinal specimens and four biopsy specimens. Five cases from ileum and two cases each from caecum and duodenum and one case each from jejunum and duodenum. Hematoxylin and eosin stained sections were studied with light microscopy and IHC for CD5, 20, 21 and cyclin D1 were done. Results: It is a retrospective study of 11 cases of intestinal lymphomas. Abdominal pain and abdominal lump were two main common presenting symptoms. NHLs were more common in the small intestine. PILs are common in adults (75% above 46 years) with male preponderance. All were NHLs and B-cell type. Five cases were diffuse large B-cell lymphoma and four cases each were mucosa-associated lymphatic tissue lymphoma and follicular lymphoma. One case was lymphomatoid polyposis or mantle cell lymphoma. Conclusion: PILs is rare and differs significantly from their gastric counterpart, not only in pathology but also with regard to clinical features, management and prognosis. Due to the lack of characteristic symptoms and a low incidence rate, PIL is misdiagnosed until serious complications occur, such as perforation and bleeding and hence needs to be accurately diagnosed.

A 67-year-old man was admitted to hospital with acid regurgitation, acute right lower abdominal pain and mild fever. Multiple suspicious mass lesions were detected in the patient's kidneys, the right side wall of his bladder and the right lower ureter, using CT urography and PET-CT. He underwent palliative surgery of the bladder and percutaneous renal biopsy. Postoperative histopathological examination and immunohistochemical staining indicated that the tumor was consistent with diffuse large B-cell lymphoma (DLBCL). Although DLBCL is by far the most common type of non-Hodgkin's lymphoma, it is rare for DLBCL to simultaneously involve the kidneys, bladder and the lower ureteric tract.

Lymphomatous involvement of the heart is extremely rare at initial diagnosis and presentation of malignant lymphoma. Worldwide, only a few cases have been diagnosed and treated during life and only four cases were diagnosed before death in Korea. We report a case of non-Hodgkin's lymphoma with two right atrial masses detected by chest computed tomography and transesophageal echocardiography. The patient was an 80 year- old man and the presenting symptoms included generalized weakness, weight loss, constipation and low abdominal pain. For diagnosis, the mass of the perinephric area was biopsied under ultrasonographic guidance, and pathologically it was determined to be malignant lymphoma, diffuse large B cell type. The patient was treated with continuous low dose cyclophosphamide and prednisolone vice standard chemotherapy because of advanced age and renal dysfunction. After 2 months of treatment the masses in the atrium and the intraabdominal masses disappeared.

Enteropathy-associated T-cell lymphoma (EATL) is a rare gastrointestinal non-Hodgkin's lymphoma, originating from intraepithelial T-lymphocyte, which is specifically associated with celiac disease. EATL most commonly presents in the sixth and seventh decades of life. We report a unique case of type I EATL in the colon with liver metastasis, which was presented with nonspecific radiological findings and at a very young age (29 years old) compared with previously published data. We suggest that EATL should be regarded as part of differential diagnosis in any patient presenting with abdominal pain, diarrhea, weight loss, and malabsorption because delay in treatment can result in an irreversible clinical outcome.

Campylobacter jejuni (C. jejuni) bacteremia is difficult to diagnose in individuals with hematological disorders undergoing chemotherapy. The cause can be attributed to the rarity of this infection, to the variable clinical presentation, and to the partial overlapping symptoms underlying the disease. Here, we report a case of a fatal sepsis caused by C. jejuni in a 76-year-old Caucasian man with non-Hodgkin's lymphoma. After chemotherapeutic treatment, the patient experienced fever associated with severe neutropenia and thrombocytopenia without hemodynamic instability, abdominal pain, and diarrhea. The slow growth of C. jejuni in the blood culture systems and the difficulty in identifying it with conventional biochemical phenotyping methods contributed to the delay of administering a targeted antimicrobial treatment, leading to a fatal outcome. Early recognition and timely intervention are critical for the successful management of C. jejuni infection. Symptoms may be difficult to recognize in immunocompromised patients undergoing chemotherapy. Thus, it is important to increase physician awareness regarding the clinical manifestations of C. jejuni to improve therapeutic efficacy. Moreover, the use of more aggressive empirical antimicrobial treatments with aminoglycosides and/or carbapenems should be considered in immunosuppressed patients, in comparison to those currently indicated in the guidelines for cancer-related infections supporting the use of cephalosporins as monotherapy.
