Large gastric folds in adults are seen in many benign and malignant conditions, but they are rare in children with malignant diseases such as non-Hodgkin lymphoma. The authors report a patient with non-Hodgkin lymphoma who had large gastric folds and jaundice as the initial symptoms. A 14-year-old boy was referred to the authors' hospital with upper abdominal pain and jaundice. A standard barium upper gastrointestinal series showed large gastric folds in the entire stomach. Magnetic resonance imaging showed a typical diffuse infiltrating type of pancreatic lymphoma. Because complete bilateral lower limb paralysis developed as a result of the epidural soft tissue mass, laminectomy and tumor resection were performed and a diagnosis of disseminated Burkitt lymphoma was established. After completing 6 months of chemotherapy, the patient has been disease-free without neurologic complications for 2.5 years.

In Taiwan, primary intestinal lymphomas (PIL) have rarely been reported and characterized. Using WHO classification, we retrospectively studied the clinicopathological features of PIL cases surgically resected in Taiwan. There were 21 cases, 14 males and seven females, with a median age of 66. The most common symptom at presentation was abdominal pain (n = 14; 66.7%). Six (28.6%) cases showed perforation and two (9.5%) intussusception. Two patients had multicentric tumors. The most common location was ileum (n = 11, 52.4%). Twenty cases (95.2%) were of B-cell lineage, and one (4.8%) was of T-cell lineage. These cases were classified as diffuse large B-cell lymphoma (DLBL) (n = 18; 85.7%), Burkitt lymphoma (n = 2; 9.5%), and enteropathy-type T-cell lymphoma (EATL) (n = 1; 4.8%). One case was lost to follow-up. The 1- and 2-yr survival rates of the remaining 20 patients were 44.4% and 26.7%, respectively. In conclusion, we describe the clinicopathological findings of a rare case of appendiceal DLBL and another one of ileal EATL, that have never been reported in Taiwan previously. We found that in Taiwan PIL occurred in the elderly, with a male predominance, showing a relatively aggressive clinical course, and a pattern similar to that seen in western countries, except for the absence of multiple lymphomatous polyposis.

The translocation between chromosomes 2 and 8, t(2;8), is well known for its strong association with high-grade Burkitt lymphoma. However, the significance of this translocation in indolent lymphoproliferative disorders is not clear. We present the case of a 75-year-old white male with left upper quadrant abdominal pain, splenomegaly, and an elevated white cell count of 30.3x10(9) cells/L (84% large lymphoid cells with scanty cytoplasm and prominent central nucleoli). Immunophenotyping revealed a clonal B-cell population coexpressing CD5, CD19, and CD20 with weak CD23 and CD25 and very weak, restricted, surface lambda. The cytogenetic analysis showed all 20 cells with t(2;8)(p12;q24.3). In addition, four of the 20 cells also showed a second translocation: t(12;17)(p13;q21). Molecular analysis using c-myc and p53 probes showed normal results with no indication of amplification of C-MYC or deletion of TP53. The patient was managed as an indo-lent/low-grade lymphoproliferative disorder with excellent response to eight cycles of fludarabine.

Pseudomembranous colitis (PMC) usually manifests as fever and diarrhea in hospitalized patients treated with systemic antibiotics. We described a case of PMC with intestinal obstruction but without diarrhea. A 60-year-old man was hospitalized for chemotherapy for the treatment of Burkitt lymphoma of the stomach. The patient became febrile and complained of crampy abdominal pain during the post-chemotherapy nadir. Plain abdominal radiography showed some intestinal gas and niveau. Because stool cytotoxin assay for clostridium difficile was positive and colon fiberscopic examination showed a pseudomembrane at the left side of the colon, and a diagnosis of PMC was made. Treatment with intracolonic vancomycin administration by colonoscopy and nasoileus tube was successful. Physicians should take into account the possibility of bowel obstruction due to PMC occurring in patients undergoing chemotherapy and perform emergency colonoscopy examination of suspected cases.

A 12-year-old patient with Wiskott-Aldrich syndrome (WAS) was referred because of recurrent abdominal pain and bloody stools. Ileocolic invagination was diagnosed and resection of the terminal ileum was performed. Pathologic examination identified submucosal tumor as the leading point of intussusception. Immunohistochemistry confirmed the diagnosis of Burkitt lymphoma. The use of chemotherapy with anti-CD20 monoclonal antibody led to complete clinical remission of lymphoma. Non-Hodgkin's lymphoma (NHL) accounts for more than 60% of the tumors in children with primary immunodeficiency, and it is the most common type of malignancy observed in WAS. Burkitt lymphoma represents 40% to 50% of all NHL cases in childhood, but in WAS it has rarely been reported. Mutation analysis of the WASP gene in this patient revealed missense mutation (105 C > T) in exon 1. WAS protein (WASP) of normal size was present at a reduced amount in peripheral blood lymphocytes. Complete lack of expression of WASP carries a greater risk for severe infections, bleeding, or malignancy development in WAS. However, rare patients with residual expression of mutated WASP, like this patient, still may develop lymphomas.

The aim of this study was to report a single center experience of primary pancreatic lymphoma (PPL) in Korea. We analyzed the clinicopathological data from four PPL patients (three male, median age 36 yr) diagnosed from 1997 to 2007 at Seoul National University Hospital. The diagnoses were: diffuse large B cell lymphoma (n=2), Ki-1 (+) anaplastic large cell lymphoma (n=1), and Burkitt lymphoma (n=1). Presenting symptoms and signs were: abdominal pain (n=4), pancreatitis (n=2), weight loss (n=2) and abdominal mass (n=1). No patient underwent surgery. The Ann Arbor stages of the patients were: IEA (n=1), IIEA (n=1), and IVEB (n=2). Two patients underwent treatment. The stage IEA patient underwent chemotherapy and radiation therapy that resulted in a complete remission. The stage IVEB patient who underwent chemotherapy relapsed. This patient underwent subsequent peripheral blood stem cell transplantation and is alive at 30 months. Two patients (stages IVEB and IIEA) without treatment died at 0.8 and 7.0 months, respectively. For PPL patients, chemotherapy-based treatment, and addition of radiation therapy, if possible, may offer good prognosis.

A 7-year-old boy presented with increasing abdominal girth and abdominal pain. Abdominal ultrasound revealed a pleural effusion and ascites. Computed tomography (CT) demonstrated a mass involving the peritoneum, mesentery, and omentum with marked ascites, mesenteric nodules, and renal involvement. Positron emission tomography (PET)/CT scan identified additional tumor within the pleura. PET/CT imaging was helpful in identifying the appropriate pleural mass biopsy site in this patient with Burkitt lymphoma.

Lymphomas showing both MYC/8q24 rearrangement and IGH@BCL2/t(14;18)(q32;q21), also referred to as "double-hit" or "dual-hit" lymphomas (DHL) are rare B-cell malignancies with a germinal center B-cell immunophenotype and heterogeneous cytologic and histologic features. Such lymphomas may arise de novo or through transformation of follicular lymphomas and are classified either as "B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL)" (most commonly), DLBCL, or, rarely, as B-lymphoblastic lymphoma. We report a case of B-lymphobastic lymphoma arising through transformation of follicular lymphoma diagnosed on peritoneal fluid cytology, flow cytometry, and cytogenetic studies in a 53-year-old man who presented with abdominal pain, shortness of breath, night sweats, extensive lymphadenopathy, pleural effusion, and ascites. Cytologic examination of the ascitic fluid showed two distinct populations of neoplastic lymphoid cells, a predominant population of larger cells with fine powdery ("blastic") chromatin, visible to prominent nucleoli and occasional small cytoplasmic vacuoles and a less numerous population of smaller cells with centrocytic morphology. Flow cytometry also showed two distinct monotypic B-cell populations, both expressing CD10, and TdT-positivity was demonstrated immunohistochemically. Fluorescence in situ hybridization (FISH) demonstrated both MYC rearrangement and IGH/BCL2 gene fusion and cytogenetic analysis showed a complex karyotype including both t(14;18)(q32;q21) and t(8;22)(q24.1;q11.2). Since DHL pursue an aggressive clinical course, respond poorly to therapy, and have a poor outcome, it is important to suspect the diagnosis when encountering neoplastic lymphoid cells that are difficult to classify in effusion cytology specimens and to order the appropriate immunophenotyping and cytogenetic studies.

A 38-year-old man complaining of abdominal pain was admitted to our hospital and diagnosed with small bowel obstruction. Whole body computed tomography(CT)scan showed moderate right pleural effusion with pleural and anterior chest wall thickening, with a mass approximately 100 mm in diameter at the terminal ileum. Histopathological and immunohistorical analysis of the endoscopic biopsy from the terminal ileum mass revealed diffuse infiltration of medium-sized, monotonous, atypical B lymphocytes with scanty basophilic cytoplasms carrying the so-called "starry sky" appearance, and primary small intestinal Burkitt lymphoma(BL)was diagnosed. Because of his advanced clinical stage(stage IV with Ann Arbor staging system)and the need for immediate treatment, he was promptly treated with cyclophosphamide and doxorubicin without surgical resection. Fortunately this initial therapy was received without the occurrence of bowel perforation. After initiating additional rituximab combined high-dose chemotherapy consisting of alternating courses of rituximab, cyclophosphamide, vincristine, doxorubicin, and methotrexate(R-CODOX-M)and rituximab, ifosfamide, etoposide, and cytarabine(R-IVAC), he achieved complete remission and remains without signs of disease now more than seven years after his last treatment. While further investigation will of course be needed, if possible, immediate chemotherapy without surgical resection is a treatment worth considering for improving the prognosis of those with small intestinal BL.

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.
