This paper gives, in detail, the causes of either liver disease or hepatomegaly in 100 patients, mostly adults, admitted to the medical wards of Angau Memorial Hospital, Lae, during 1968 and 1969. The major findings included liver cell carcinoma, cirrhosis (often with chronic active hepatitis), tropical splenomegaly, pericholangitis and hepatitis. There were 27 with miscellaneous findings including ten with normal, or almost normal, livers despite the definite enlargement. Patients with liver cell carcinoma presented late in the course of their illness and had a poor prognosis. Others, with pericholangitis, had clinical features of portal hypertension indistinguishable from that complicated cirrhosis. There was an unexpected number with chronic active hepatitis and a liver biopsy is essential for such a diagnosis. Hepatic sinusoidal lymphocytosis is almost invariably found in patients with TS but may occasionally be found in those with a non-palpable spleen. Patients with right heart failure of chronic respiratory disease, and jaundice of acute pneumonia were excluded from the study.

Of 50 patients in Thailand suspected clinically of having exanthem, subitum, 31 (62%) were serodiagnosed as HHV-6 infection. Sixteen strains of HHV-6 from 31 patients (52%) whose antibody titers had converted during convalescence were isolated during the acute phase. The disease occurred in infants from 3 months to 1 year of age and most frequently at age 4-6 months. Antibody only to HHV-6 converted in 23 of 50 patients (46%), and seroconversion to HHV-6 and dengue virus was observed in 7 patients (14%), and to HHV-6 and Coxsackie B virus in 1 case (2%). In the 23 patients in whom seroconversion only to HHV-6 was observed, all had fever and rash which appeared after subsidence of the fever. Lymphadenopathy and relative lymphocytosis were recognized, associated with diarrhea, vomiting, running nose, cough and hepatomegaly. Febrile convulsions were seen in some cases. All patients recovered completely within a week.

A 33-year-old man was hospitalized because of thrombocytopenia and severe splenomegaly. On admission 78% of peripheral lymphoid cells were abnormally large, with pale cytoplasm. Flow cytometry of the abnormal lymphocytes showed that they expressed CD 2, CD 3, CD 11, CD 16, and CD 56, but not CD 4 nor CD 8, so they were T-cell large granular lymphocytes (T-LGL). Abnormal lymphocytes obtained from a lymph node expressed CD 2, CD 16, CD 38, and CD 56, but not CD 3, CD 4, and CD 8, so they were natural killer(NK) cells. Splenectomy was performed and the operative specimen showed diffuse infiltration of pleomorphic lymphocytes, probably chronic lymphocytic leukemia cells. After splenectomy, the platelet count returned to normal but the lymphocytosis continued. Two years after discharge, chemotherapy was done because of thrombocytopenia and hepatomegaly. The patient died of disseminated intravascular coagulation arising from sepsis. The differences and similarities between peripheral and lymph-node lymphocytes suggest that LGL and NK cells may be differentiated from the same kind of cell, somewhat differentiated from stem cells.

Chronic lymphocytic leukaemia was diagnosed in 1957 in a 29-year-old male patient who lived 31 years after that time. At the time of diagnosis he was in good general condition with the enlarged liver (4 cm) and spleen (5 cm). In peripheral blood the leukocyte count was 47 x 10(9)/1 with 80% lymphocytes (38 x 10(9)/1), Hb 106 g/1; the bone marrow showed hypercellularity with predominance of lymphocytes. Treatment with corticosteroids was during 1958-1966. In 1967 Chlorambucil was given for 3 months, in 1972 for one month, inducing normalization of leukocyte count, 5.7 x 10(9)/1 with 40-50% of lymphocytes (3 x 10(9)/1). In 1977 the bone marrow showed slight lymphocytosis (38%). Numerous infections were recorded. Splenomegaly disappeared in 1980. In 1982 macrocytic anaemia was observed. Diagnosis of pernicious anaemia was established based on megaloblastic bone marrow and positive Schilling test. Vitamin B12 treatment resulted in reticulocyte response (crisis) and normalization of haemoglobin level. In 1988 light anaemia and melena appeared. Gastroscopy revealed lesions in the fornix histologically identified as ventricular carcinoma. It can be presumed that the appearance of pernicious anaemia as an autoimmune disease is analogous to other autoimmune complications in chronic lymphocytic leukaemia (haemolytic anaemia, thrombocytopenia).

A case of granular lymphocyte proliferative disorder with squamous cell carcinoma of penis is described. A 77-year-old Japanese male was admitted to our hospital in March, 1989 because of ulceration of penis and lymphocytosis. He had hepatomegaly and lymphadenopathy but not splenomegaly on physical examination. The WBC count was 10800/microliters with 83% of granular lymphocytes. Thrombocytopenia (32000/microliters) and mild anemia were also demonstrated. Bone marrow aspirate showed hypercellular marrow with 84% of granular lymphocytes. Proliferative granular lymphocytes were CD2+ CD3+ CD4- CD8- CDw29+ and exhibited ADCC activity but not NK activity. On March 15, amputation of penis was performed. But his lymphocytosis didn't change and thrombocytopenia increased. Thus we considered his granular lymphocytosis was neoplastic rather than reactive. Our case seemed to be rare and was compared with previous reports.

The T cell chronic leukemias encompass a broad spectrum of diseases involving mature post-thymic T cells. With the development of highly specific marker studies, clear patterns of immunophenotypic and functional characteristics of the involved cells have emerged. These studies, along with the development of molecular probes for the T cell receptor gene loci, have helped to elucidate the pathogenetic basis for the highly variable clinical course which has been described for patients with these disorders. The T gamma lymphocytosis syndrome has been identified as a benign chronic illness which is nevertheless usually a monoclonal neoplastic proliferation of large granular lymphocytes. These patients represent a distinct clinical entity characterized by splenomegaly, neutropenia, and peripheral blood lymphocytosis. The cells of TGLS are large granular lymphocytes and display many of the immunophenotypic and functional characteristics of NK and K cells. These cells have been implicated pathogenetically in the associated cytopenias seen in the illness, but a clear link has not been established. Although the lymphoproliferative manifestations of the disease are usually easily controlled with low-dose alkylating agents, therapy of the neutropenia has been relatively unsuccessful. Separating these patients from the rest of the spectrum of the T cell chronic leukemias has provided insight into the other disorders as well. It has established that T-CLL and T-PLL are, in fact, extremely rare. T-CLL is similar to its B cell counterpart, except that patients have a higher incidence of skin infiltration. Available data suggest that the prognosis in T-CLL is actually less variable, and somewhat worse, than generally believed when those patients were viewed in conjunction with the patients with the more benign TGLS. T-PLL is an extremely aggressive disease characterized by massive splenomegaly, lymphadenopathy, and skin infiltration. It is refractory to most forms of therapy. These illnesses are again phenotypically distinct from the retrovirus-associated ATLL. Most of the early cases of T-CLL reported from Japan were probably ATLL; this disease is characterized by pronounced splenomegaly, hepatomegaly, lymphadenopathy, and skin infiltration. It has an extremely aggressive natural history, and survival is usually less than 1 year from diagnosis. The rapid development of sophisticated immunologic and molecular techniques for analyzing T cell proliferations has allowed highly specific distinctions to be made among the cells of origin of the different T cell chronic leukemias. It is hoped that increased understanding of the immunologic and functional characteristics of these diverse T lymphoid populations will provide further insights which will have an impact on directed therapeutic interventions in the future.

Infectious mononucleosis as a manifestation of primary Epstein-Barr virus infection occurs uncommonly in adults over age 40. While fever is almost universal, older patients with the disease often present without lymphadenopathy, pharyngitis, splenomegaly, lymphocytosis or atypical lymphocytes. Jaundice and hepatomegaly occur more commonly in older patients than in adolescents and create diagnostic confusion. Often, infectious mononucleosis in this age group is confused with lymphoma, leukemia or biliary obstruction, or is classified as "fever of unknown origin."

A 68-year-old woman with Felty's syndrome had massive hepatomegaly. Liver biopsy showed diffuse infiltration of the sinusoids with mature lymphocytes (sinusoidal lymphocytosis of the liver). Nodular regenerative hyperplasia of the liver and portal fibrosis were not found. Although liver involvement is frequent in association with Felty's syndrome, sinusoidal lymphocytosis of the liver is unusual.

The authors present the clinical history of the first case of benign hemophagocytic syndrome diagnosed in Panama. The patient, a 4 year old girl, presented with fever, anemia, cervical lymphadenitis, hepatomegaly, lymphocytosis and histophagocytosis of red cells, lymphocytes, neutrophils and platelets. Spontaneous remission of the fever occurred sixty days after the onset of the disease. Although it was not possible to demonstrate serologically that the syndrome was due to acute toxoplasmosis, she was treated with sulfadiazine and pyrimethamine for fifteen days, on the 37th hospital day, and with clindamycin for ten days, consecutively. Remission occurred seventy days after the onset of fever. A second serological examination for toxoplasmosis (immunofluorescent antibodies) was positive in a titer of 1:2048 again, nine months after the first serology.

From December 1982 to June 1985, we diagnosed LAV/HTLV-III infection in 16 children of African origin living in Belgium or referred to one of the hospitals participating in this study. Diagnosis was proven in seven of them by isolation of virus of the LAV/HTLV-III group. In the nine others, LAV/HTLV-III infection was highly probable because of the presence of antibodies against the virus (seven subjects) or clinical and immunological evidence of immune deficiency associated with a parental history of LAV/HTLV-III infection (two subjects). Five of these children had a severe illness starting in the first months of life (range 20 days--4 months) and died within 4 months (range 19 days--10 months). Eight children presented later in life (mean age 35 months, range 2-66 months) with a milder and more chronic disease characterized by the presence of generalized lymphadenopathy (6/8), hepatomegaly (5/8), splenomegaly (5/8), interstitial pulmonary infiltration (4/8), parotid swelling (3/8), CSF lymphocytosis (3/5), diarrhoea without pathogen isolated (1/8) and fever (1/8). At least one of the parents of each child was of African origin. At the time of birth of their child two mothers and one father had an AIDS-related complex. After a mean period of 34 months (range 3-87 months) five fathers and six mothers had a symptomatic LAV/HTLV-III infection (AIDS or AIDS-related complex).
