The incidence of non-Hodgkin's lymphoma (NHL) has greatly increased in the AIDS population. It has been estimated that 8% to 27% of newly diagnosed cases of NHL are related to AIDS. The vast majority are clinically aggressive B cell-derived lymphomas. AIDS-associated NHLs are classified according to their anatomic site of location into three classes: (1) systemic (both nodal as well as extranodal), (2) primary central nervous system, and (3) body cavity-based lymphomas. We present a case report of a patient with HIV infection who presented with abdominal pain and distension and was found to have an intraabdominal type of Burkitt's lymphoma. This case underlines the following points: 1. In the evaluation of acute abdominal disease in a patient with AIDS, both AIDS-related infections as well as malignancies should be sought in the differential diagnosis. 2. Computed tomographic scanning of the abdomen is the modality of choice for characterization of disease as well as direction of appropriate therapy. 3. AIDS-related NHL remains an important biologic model for investigating the development and progression of lymphomas in the immune-deficient host. 4. With the improved survival of patients with AIDS secondary to better prevention and treatment of infections, there may be an increase in AIDS-associated malignancies; therefore, further research pertaining to the development and characterization of therapy modalities of such malignant tumors is mandatory.

Primary pancreatic lymphoma (PPL) is a very rare disease. We report five cases of PPL (4 men and 1 woman, mean age 65 years) diagnosed and treated at our Institution from 1987 to 1997. None of these patients had evidence of extrapancreatic disease and they were categorized as PPL involving pancreas only (stage IE, 3 patients) or pancreas and peripancreatic lymph nodes (stage IIE, 2 patients). The most common presenting symptoms were abdominal pain and weight loss. Imaging techniques showed a mass of the pancreatic head in all cases. The histological diagnosis (3 diffuse-large cell non-Hodgkin's lymphoma and 2 lymphoplasmacytic lymphoma/immunocytoma) was made by ultrasound-guided fine needle aspiration biopsy and tissue core fine-needle biopsy in three patients and by surgery in the remaining two patients. The three patients diagnosed by percutaneous biopsy were treated with chemotherapy as front-line therapy and two of them received also local radiotherapy; one of these patients is still alive in complete remission at 69 months, one died of an unrelated disease at 67 months and one died of lymphoma relapse at 88 months. Two patients underwent pancreaticoduodenectomy plus adjuvant chemotherapy; one of them died of recurrent cholangitis 8 months after surgery while the other one is still alive in complete remission after 160 months. This study shows that: 1) imaging techniques can suggest the suspicion of PPL but are unable to distinguish PPL from pancreatic adenocarcinoma; 2) histological diagnosis can be easily obtained by percutaneous US-guided tissue core biopsy; 3) surgery can be avoided both for diagnosis and therapy but the treatment of choice of PPL may only be evaluated on a larger series of patients.

We review the literature on primary hepatic lymphoma (PHL). PHL is a rare malignancy, and constitutes about 0.016% of all cases of non-Hodgkin's lymphoma. It has been reported to occur with increased frequency in patients with chronic hepatitis C infection. Most patients with PHL present with abdominal pain, constitutional symptoms and have hepatomegaly on examination. Imaging studies reveal solitary, or less often, multiple masses in the liver. The predominant histology is B-cell lymphoma, most commonly diffuse large cell type. Most patients are treated with chemotherapy, with some physicians employing a multimodality approach incorporating surgery and radiotherapy with chemotherapy. The prognosis is variable, with good response to early aggressive combination chemotherapy.

We report a 73-year-old man presenting with fatigue, lymphadenopathy and weight loss. He had no abdominal pain, fever or night sweats. Physical examination revealed a palpable 1.4-cm hard nontender lymph node behind the left sternocleidomastoid muscle and a palpable 2-cm lymph node in the left axilla. Bone marrow examination and excisional biopsy of the lymph node behind the left sterno-cleidomastoid muscle showed a CLL-type non-Hodgkin's lymphoma (CLL-type NHL). Staging by CT scanning revealed, besides axillary and mediastinal adenopathy, an unexpected mass in the stomach. Gastroscopy and pathological evaluation showed a gastrointestinal stromal tumour (GIST) with immunohistochemical staining for CD 34 and CD 117. The patient was treated with imatinib. CLL-type NHL and GIST both tend to occur in middle-aged and older patients. A double-tumour consisting of both these tumours is rare: the incidence is estimated to be 3 per 10 billion people.

We report here on a case of non-Hodgkin's lymphoma in which liver involvement was the predominant clinical manifestation. A healthy 44-year-old man presented with upper abdominal pain, hepatosplenomegaly, thrombocytopenia, elevated AST, ALT and bilirubin, and marked elevation of lactate dehydrogenase and alkaline phosphatase. The abdominal CT scan showed only diffuse hepatosplenomegaly and uneven contrast enhancement of the spleen without any definite mass of the liver and spleen. US-guided aspiration biopsy of liver and the histologic examination confirmed a diagnosis of non-Hodgkin's lymphoma, the diffuse large B cell type. Bone marrow biopsy showed the infiltration of malignant lymphoma cells. PET-CT showed an increased FDG uptake of the liver, spleen and long bones. The patient was treated with combination regimen of cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy. Even in the absence of a mass lesion or lymphadenopathy, primary hepatic or hepatosplenic lymphoma should be considered in differential diagnosis of hepatitis or liver cirrhosis, especially for patients with diffuse hepatosplenomegaly and markedly elevated LDH.

The case of a 69-year-old female patient come to our observation with the diagnosis of non-Hodgkin's lymphoma on histology and cystoscopy is discussed. Symptoms were characterized by dysuria, vaginal spotting and abdominal pain. CT and NMR for staging and control CT during chemotherapy were performed. They documented marked reduction of the neoformation protruding into the bladder and concentric urethral thickening associated with volumetric stability of intercavoaortic lymph node involvement and stable condition of the other localizations.

We report on a 54-year-old male patient with an aggressive T cell non-Hodgkin's lymphoma with abdominal manifestation undergoing autologous peripheral blood stem cell transplantation after high-dose chemotherapy in April 2003. About 4 months after transplantation, he developed severe upper abdominal pain. Ultrasound examination, X-ray, computed tomography of the abdomen and cardiac diagnostics could not explain the symptoms. While empiric therapy with high-dose acyclovir was started, we could document herpetic lesions in the gastric antrum by endoscopy. The epigastric pain rapidly decreased within several days after the start of acyclovir therapy. No herpetic skin lesions were observed at any time during the disease. This report demonstrates the importance of viral-induced gastritis in the differential diagnosis of severe abdominal pain in patients receiving autologous peripheral blood stem cell transplantation.

Primary pancreatic lymphoma is rare, comprising 0.2-4.9% of all pancreatic malignancies and less than 1% of cases of non-Hodgkin's lymphoma. Many patients are diagnosed with lymphoma after radical resection. We report a rare presentation of diffuse large B cell lymphoma, appearing as a primary tumor of the pancreas. A 61-year old female was admitted to the hospital with the complaint of right upper abdominal pain. Computed tomography of the abdomen showed a well defined mass located at the head of the pancreas. A frozen section of pancreas, during laparotomy, revealed lymphoma. The patient received 6 cycles of chemotherapy and is currently in complete remission. This case underscores the importance of differentiating primary lymphoma from the more common adenocarcinoma of the pancreas as treatment and prognosis differ significantly. Primary pancreatic lymphoma should be considered in the differential diagnosis of pancreatic tumors and an attempt to obtain a tissue diagnosis is always necessary before proceeding to radical surgery, especially on young patients.

We present four patients with non-Hodgkin's lymphoma of the small bowel. Three of the patients were men. Two patients presented with acute abdomen due to tumoral perforation and the remaining 2 presented with abdominal pain and other effects of the mass. The tumors were located in the ileum (1 patient), jejunum (2 patients) and jejunoileum (1 patient). All patients underwent resection of the affected segment. Three patients had large B-cell lymphomas and the remaining patient had a T-cell lymphoma associated with celiac disease. Different combinations of chemotherapy were administered. Only the patient with T-cell lymphoma died due to disease progression. Clinical aspects and the therapeutic strategy used in these tumors are discussed.

Primary intestinal lymphoma with spontaneous perforation and after systemic chemotherapy is rare. The present study summarizes retrospectively the outcome of eight free intestinal perforated patients diagnosed with intestinal non-Hodgkin's lymphoma. Two patients had a history of systemic chemotherapy before perforation. The most common symptoms of the patients were abdominal pain, nausea, vomiting, weight loss, and fever. Sites of perforation were ileum in four, jejunum in two, cecum in one, and sigmoid colon in one patient. Synchronous lymphoma was present in three patients. The perforation was closed by primary closure in three patients. Resection/anastomosis was performed in four patients and sigmoid colostomy was performed in one patient. Three patients were lost due to leakage or septicemia. Intestinal lymphoma might be kept in mind as a cause in free intestinal perforations. Because of the high mortality rate early diagnosis and treatment are important to improve the prognosis of bowel perforation in patients with non-Hodgkin's lymphoma.
