Two cases of Richter's syndrome are reported (in a 62 and 64 years old man) consistent with the appearance of B cell lymphoma of high malignancy in the course of CLL (low malignancy B cell lymphoma). In one patient, after 8-, and in the other one--after 53 months since the diagnosis of CLL, there was rapid clinical deterioration with lymphadenopathy, hepato- splenomegaly, fever and progressive cachexia, anemia and thrombocytopenia and leukopenia, unrelated to treatment. Both patients died, 4 and 3 months respectively, since the appearance of these symptoms. In the first cases Richter's syndrome was diagnosed histopathologically from the autopsy material. In the liver, spleen, adrenals and bone marrow, in addition to the characteristic infiltrates of CLL (small lymphocytes) there were areas of large cell proliferation consistent with high malignancy lymphoma. In the other case, the infiltrates of large cell lymphoma were found in the gall bladder removed because of acute cholecystitis, and in the lymph node from the hepatic hilar area. Immunocytochemical studies performed on the biopsy material indicated that the neoplastic cells had markers of B lymphocytes and cytoplasmic IgM kappa, as lymphocytes of CLL. In patients with CLL, who display rapid clinical deterioration and general symptoms with cachexia, the possibility of Richter's syndrome should be considered, and appropriate morphological studies performed.

One hundred patients with suspected acute abdominal inflammation were imaged at 0.5, 2-3, 4-6, and 24 hours after the administration of Tc-99m HMPAO labeled autologous leukocytes. Scan findings were retrospectively compared with final diagnosis, serum C-reactive protein (CRP), and antibiotic treatment. Clinical findings were confirmed with surgery, barium enema, or sigmoidoscopy in 61 patients, and diagnosis was based only on clinical findings in 13 patients. In 26 patients, symptoms subsided before a final diagnosis was made. Tc-99m leukocyte images were positive in 45 of the 61 patients with a confirmed diagnosis, including all patients with acute cholecystitis (N = 4) and inflammatory bowel disease (N = 8). They were also positive in nineteen out of 25 patients who had acute colonic diverticulitis and in 6 out of 7 who had intra-abdominal abscesses. Abnormal activity was found in patients with colonic carcinoma, small bowel infarction, and acute appendicitis. Abnormal activity was visualized in 0.5-hour images in all but one of the positive cases. With the exception of two postoperative cases, malignant lymphoma, and a liver abscess, a CRP level of greater than 75 mg/L was associated with positive image findings. Antibiotic treatment did not affect imaging findings. Imaging with Tc-99m labeled leukocytes appears to be valuable for detecting and localizing abdominal inflammation, and three-phase imaging during the first 4-6 hours is recommended. In some cases, 24-hour images may be useful for distinguishing small bowel from large bowel inflammation.

Although there are many complementary and supplementary types of diagnostic imaging of the liver, a logical sequence for most liver pathology begins with high-quality ultrasound. It is noninvasive and inexpensive but very operator dependent. In other settings, CT may be the preferable screening modality, as it gives an excellent picture of the global anatomy and is easily reproducible. Frequently, the two modalities are complementary and indicated; on other occasions, one method will suffice. Radionuclide evaluation of the liver is usually reserved for hepatobiliary imaging for biliary obstruction or the question of acute cholecystitis and tagged-red cell scanning for hemangioma. It is also frequently used for gallium scanning in hepatoma, but lymphoma and inflammatory diseases are also gallium avid. The invasive imaging tests of the liver--angiography and transhepatic and endoscopic retrograde cholangiography--are performed when insufficient information is obtained by the other methods (as in diagnostic transhepatic cholangiography) or when the procedure offers therapy (as for biliary drainage, percutaneous transhepatic removal of common bile duct stones, percutaneous cholecystosis with gallstone dissolution and liver embolization, or the angiographic evaluation for portal shunting or liver resection). The impact of magnetic resonance imaging and fourth-generation raid angiotomography CT scanning has yet to be felt. The use of intraoperative ultrasound is to be encouraged prior to liver resection because it can demonstrate lesions as small as 3 mm in diameter.

Numerous abdominal manifestations were noted among 600 patients undergoing treatment at Hospital Laennec for various stages of infection by the acquired immunodeficiency virus. These included violent abdominal pain in 30% of cases, the development of abdominal lymphoma, and occasionally alarming pseudo-surgical syndromes. Diagnosis is difficult, all the more so since authentic emergencies may be aggravated by the immunodeficiency state. 18 cases were collected in 3 years and included 6 cases of acute cholecystitis and 2 of appendicitis. The gangrenous and extensive nature of infection was generally noted and required appropriate antibiotic therapy.

A 62-year-old woman presenting with a clinical picture of acute cholecystitis was found to have lymphoma upon pathological examination of the gallbladder. Such a presentation of large-cell non-Hodgkin's lymphoma is unique and has not been described before.

A case of primary lymphoma of the gallbladder is described which is rare in the medical literature. A 76 year old man presented with acute cholecystitis and septicaemia. Investigation showed a lung abscess and a gallbladder mass. The mass was thought to be an empyema and cholecystostomy was performed. Biopsy of the gallbladder wall showed high-grade B cell lymphoma. The patient unfortunately succumbed to overwhelming septicaemia in the postoperative period. Postmortem examination confirmed primary lymphoma of the gallbladder without dissemination.

The clinical course of patients with hematological disease, especially after treatment, is often complicated by gastrointestinal infections. Between 1986 and 1990 a total of 18 patients affected with hematologic disease and presenting with an acute abdomen were admitted to the surgery department at the University of Rome "La Sapienza". Most patients were affected with acute or chronic myeloid leukemia (61%) and lymphoma. Five patients with acute appendicitis, three with necrotizing enterocolitis, three with spontaneous hemoperitoneum, three with cholecystitis, two splenic infarctions and two intestinal occlusions were diagnosed. Symptoms were often vague and non specific and blood counts revealed neutropenia in all but two patients, while anemia was characteristic in spontaneous hemoperitoneum and in neutropenic enterocolitis. Fungemia occurred in only two cases while bacteremia was present in seven. The most critical patients were those affected by neutropenic enterocolitis and acute cholecystitis. Sonography was meaningful in the diagnosis of hemoperitoneum, splenic infarct and acute cholecystitis. All patients underwent surgical procedures within 48 hours of admission to the department. In all cases peritoneal washing was performed and at least one peritoneal drainage was left. In all cases of necrotizing enterocolitis, intestinal resections, either ileal or colonic, were followed by an immediate anastomosis in two layers. Intensive hematological and antibiotic post surgical care was performed in all patients. Seven patients presented minor complications (38.8%), and only one died (5.5%). Emergency surgical treatment may be safely carried out in patients with hematological diseases presenting with an acute abdomen. Intensive postsurgical care is mandatory for the recovery of patients and the patient's critical condition should not be a deterrent to surgical intervention.

Acquired immunodeficiency syndrome (AIDS) caused by the human immunodeficiency virus (HIV) may turn out to be the largest lethal epidemic of infection ever. The estimated global number of HIV-infected adults in 1993 was 13 million, with projections of up to 40 million by the year 2000. Human immunodeficiency virus infections and AIDS are relevant to surgeons with respect to the surgical management of AIDS patients in general, the treatment of the increasingly long list of surgical complications specific to AIDS patients in particular, and the risks of patient-to-surgeon and surgeon-to-patient HIV transmission. Because of migration of individuals and populations throughout the world, even surgeons practicing in relatively unaffected regions should be familiar with the potential surgical implications of AIDS. Ethical considerations arise, as well. Are surgeons obliged to operate on HIV-positive or AIDS patients? Some surgeons adhere strictly to the Hippocratic Oath, whereas others reserve the right to be selective on whom they operate, except in emergencies. Other common ethical considerations in the AIDS patient are similar to those arising in the terminal cancer case: whether to operate or not; whether to provide advanced support such as total parenteral nutrition or hemodialysis. Answers are not simple and require close collaboration between the surgeon, the AIDS specialist, and involved members of other specialties. Emergency operations become necessary to treat AIDS independent disease such as acute cholecystitis and appendicitis or AIDS-related life-threatening conditions such as gastrointestinal bleeding, obstruction, perforation, or ischemia complicating Kaposi's sarcoma, lymphoma, and cytomegalovirus or disseminated nontuberculous mycobacterial infections. Delays and errors in diagnosis are frequent. Poor nutritional state with weight loss, low serum albumin, and leukocyte count prevails in most patients requiring emergency operations and account for a high mortality. By applying solid judgment and selecting management appropriately, the surgeon has the ability to prolong life and to improve the quality of life for these unfortunate patients, and to do so with extremely minimal risk to himself and his team.

Two Taiwanese patients with gallbladder small cell carcinoma are reported. One is a 79 year-old male, the other, a 86 year-old female. They both presented with the symptom/signs of acute cholecystitis and underwent cholecystectomy. An intramural mass in the gallbladder neck region was found in the first patient, while the second patient had a transmural indurated tumor in the gallbladder body with extension to the neck region. Characteristic histological and immunohistochemical features of small cell carcinoma were present in both, and electron dense neurosecretory granules were identified in the second. To our knowledge, the second patient is the oldest ever reported. The first patient received chemotherapy directed toward the initial erroneous diagnosis of non-Hodgkin s lymphoma and developed liver metastasis in two months. The second patient did not receive chemotherapy due to her poor general condition and local recurrence occurred in six weeks. Both passed away three and five months after surgery, respectively.

Primary non-Hodgkin lymphoma (NHL) of the gallbladder (GB-NHL) is exceedingly rare. We present our experience on a 78-year-old male with chief complaints of fever, chills, and epigastric dull pain. Abdominal computed tomography (CT) scan showed a few stones and focally thickened gallbladder wall. He received cholecystectomy under the preoperative diagnosis of acute cholecystitis with septic shock, while pathologic examination revealed cholelithiasis and diffuse large B-cell lymphoma without acute inflammation. Staging procedures revealed a stage IE tumour and the patient received adjuvant radiotherapy. Relapse as a large retroperitoneal mass was noted 32 months later and he passed away three years after initial diagnosis. A literature review revealed 20 cases of GB-NHL. We find that, including our current case, the median age is 63 years and 8 of 19 (42%) tumours are associated with gallstones. The mean and median survival of 15 patients with complete follow-up information is 75 and 36 months, respectively. Mucosa-associated lymphoid tissue (MALT) lymphoma seems to carry a longer survival than non-MALT lymphomas.
