A nineteen-month-old child presented with a febrile illness, skin rash, painful swelling of the joints, lymphadenopathy and hepatosplenomegaly. Pseudomonas was cultured from the blood during life and, subsequently, at autopsy. Autopsy revealed a generalized panarteritis involving the coronary, retroperitoneal and pulmonary arteries with thickening of arterial walls and narrowing of the lumina. Thrombi and foci of necrosis and infarcts were found in many organs. Numerous bacilli were present in fresh lesions, but not in the organizing lesions. Periodic acid-Schiff-positive deposits were found in occasional macrophages, in walls of affected vessels, in the marginal sinuses of lymph nodes and diffusely in epicardial and retroperitoneal adipose tissue. The findings suggest that some or even all cases of Kawasaki's disease and infantile polyarteritis nodosa may be caused by Pseudomonas sepsis. It is also suggested that the vasculitis and paucity of inflammatory reaction in many cases of Pseudomonas sepsis might be related to the fact that many strains of Pseudomonas produce high-molecular-weight levan (or another polysaccharide). This compound is known to inhibit the inflammatory reaction and to increase bacterial pathogenicity.

A newborn infant presented with hepatosplenomegaly, rash, anemia, and leukocytosis at one day of age and manifested characteristic myeloid metaplasia by one mouth of life. Vitamin B12 and leukocyte alkaline phosphatase were elevated and platelet aggregation was impaired. Myelofibrosis was not present and neutrophil function was preserved. An unidentified high isoelectric point hemoglobin with unusual chromatographic and electrophoretic behaviors was found to comprise 12% of the total hemoglobin. The myeloid metaplasia and mutant hemoglobin disappeared over the subsequent months without biochemical or clinical residual. The available evidence was consistent with the mutant hemoglobin representing either a gamma chain or clonal embryonic chain variant. The inability to clarify prognostic factors in these unusual myeloproliferative syndromes suggests caution in the initiation of cytotoxic therapy.

A generalized form of cytomegalic disease in newborns is relatively rare. According to the author's data, only one case of cytomegalia was observed during post-mortem investigations of 1724 newborns and young children. This was a full-term child which was born with jaundice, generalized petechial rash and hepatosplenomegaly. Histological investigations revealed cytomegalic cells in the lungs, liver, kidneys and parotid salivary glands; in the brain there was noted calcification of the walls of the lateral ventricles. In the stroma of organs lymphoid infiltration with proliferation of histiocytes was observed.

Nineteen patients whose bone marrow smears showed histiocytic hyperplasia with prominent hemophagocytosis were found to have a clinicopathologic syndrome associated with active viral infection. High fever, constitutional symptoms, liver function, and coagulation abnormalities and peripheral blood cytopenias were characteristic findings. Hepatosplenomegaly, lymphadenopathy, bilateral pulmonary infiltrates, and skin rash were often present. Fourteen of the patients were immunosuppressed. Active infection by herpes group viruses was documented in 14 patients and by adenovirus in 1. The bone marrow of most patients also showed decreased granulopoiesis and erythropoiesis with normal to increased numbers of megakaryocytes. Treatment generally consisted of supportive therapy and withdrawal of immunosuppressive drugs. Thirteen patients recovered. Lymph node biopsy and autopsy material showed generalized histiocytic hyperplasia with hemophagocytosis. The relationship of this disorder to familial hemophagocytic reticulosis, familial erythrophagocytic lymphohistiocytosis, histiocytic medullary reticulosis, and malignant histiocytosis is discussed. Immunosuppressive and cytotoxic therapy may be contraindicated in the treatment of this virus-associated syndrome.

Two patients with immunoblastic lymphadenopathy had lymphadenopathy, hepatosplenomegaly, rash, dysproteinemia, constitutional symptoms, and typical morphologic findings or lymph node obliteration by immunoblasts and plasma cells, proliferation of aborizing vessels, and infiltration with amorphous, eosinophilic material. One patient had massive pulmonary infiltrates that responded to steroid therapy early in the course of the disease, but recurred and were found, at autopsy, to represent immunoblastic invasion of the lung. In both cases, a severe peripheral neuropathy developed during the course of the disease. One patient was addicted to dextroamphetamine for 20 years. Response to corticosteroids and cytotoxic therapy was initially rapid and complete, but refractoriness developed as seen in postmortem findings of extensive visceral involvement.

Eight cases of angio-immunoblastic lymphadenopathy were recently diagnosed at the University Hospital of Geneva. The disease was characterized by generalized adenopathy, hepatosplenomegaly, fever, and sometimes skin rash. Six patients had polyclonal dysproteinemia and two displayed autoimmune disorders, e.g. Coombs' positive hemolytic anemia. Lymph node biopsy was a decisive pointer for the diagnosis. Four patients died, two of them from immunoblastic lymphoma. Four other patients are in remission, the longest follow-up being 91 months. Analysis of 213 cases from the literature shows the following features:--Males and females are equally affected, with a predominance after the age of 50.--The onset is characterized by constitutional symptoms (75%) and fever (65%), sometimes following exposure to drugs.--The signs are generalized adenopathy (91%), splenomegaly (66%), hepatomeagly (65%), and skin rash (46).--Polyclonal hypergammaglobulinemia (76%) is found, together with anemia (78%) which is often autoimmune in origin (58%).--The course is often unfavourable and the mortality is over 55%, largely due to opportunistic infections and/or development of immunoblastic lymphoma.

From July, 1974 to February, 1978, we managed 12 infants with listeriosis. This infection presented in two distinct forms: an early-onset type (nine patients), often representing a congenital infection following maternal illness, and a late-onset type in which the patient presented with meningitis (three patients). Of our nine infants with early-onset disease, three died, three developed permanent sequelae, and only three were normal at follow-up. Appropriate early management in the perinatal period may improve the outlook in this condition. Affected infants were often premature and had pneumonia, rash, and hepatosplenomegaly at birth. Prenatal clues to the diagnosis included maternal fever, abdominal pains, and leukocytosis with meconium staining of the preterm amniotic fluid. Examination of gastric aspirate at birth showed gram-positive coccobacilli. Antibiotic therapy should be started prenatally and continue for three weeks after birth to prevent recurrences of the late-onset type. This late-onset disease presented as meningitis after the second week of life and responded well to antibiotics. Our three patients recovered without sequelae.

A case of immunoblastic lymphadenopathy which underwent transformation into immunoblastic sarcoma is reported. A 64-year-old man presented with a rash, generalised lymphadenopathy, and hepatosplenomegaly. A cervical lymph node removed at biopsy showed the features of immunoblastic lymphadenopathy with the presence of heavy chain classes IgG, IgM, and IgA and both kappa and lambda light chain types in the cytoplasm of the immunoblasts. No such immunoglobulins could be demonstrated in the lymph nodes obtained at necropsy when the patient died of widespread immunoblastic sarcoma. The biological evolution and histogenesis of the disease are discussed and the current literature is reviewed.

Six patients have been observed which exhibited the features of the so called immunoblastic lymphadenopathy. The histological and clinical findings allow to distinguish the disease from both the malignant lymphomas and other forms of benign pseudolymphomas. The most important clinical features are severe general symptoms, generalised lymphadenopathy, hepatosplenomegaly, skin rash and a variety of abnormal reactions in the B-cell system such as hypergammaglobulinaemia, a transient positive Coombs test and the appearance of plasma cells in the peripheral blood. Evidence for a neoplastic nature of the disease is lacking. Nevertheless, the course of the disease may be progressive and fatal, but spontaneous remissions and subsequent relapses have also been essential part of the therapeutic strategy. Immunosupressants such as corticosteroids may have a positive effect in cases with immunological complications.

The general clinical and pathological findings of angio-immunoblastic lymphadenopathy are reviewed and illustrated by a case-report with involvement of the tonsils. Our patient showed all the characteristic signs of this disease, including fever, pruritus, rash, generalized lymphadenopathy and hepatosplenomegaly. Histologically the wellknown triad of arborizing postcapillary vessels, proliferation of immunoblasts and plasma-cells, as well as deposition of PAS-positive interstitial material was found. Laboratory findings included a polyclonal hyperglobulinemia and a hemolytic anemia. Treatment consisted of corticosteroids and supportive medications. The prognosis is generally poor, with a median survival of 13 months. At present, the cause is unknown.
