Over a 4-year period 203 patients with various types of leukaemia were treated by the Haematology Unit at the Johannesburg Hospital. Ten of them were suffering from the condition known as hairy-cell leukaemia or leukaemic reticulo-endotheliosis. They were all men, and ranged in age from 29 to 67 years (mean 56 years). The majority presented with pancytopenia, and there was invariably splenomegaly, while lymphadenopathy was rare. Hairy cells were identified microscopically in the peripheral blood of 7 patients and in 5 the specific cytochemical marker, tartrate-resistant acid phosphatase, was present. In addition, in a further 2 patients this feature, which was not identified in the peripheral blood, was found in the splenic cells. The bone marrow trephine biopsy specimens characteristically showed extensive lymphoid infiltration associated with a dense disordered deposition of reticulin fibres. Electron microscopical and immunological studies proved to be of doubtful diagnostic value. Splenectomy was carried out on 9 patients, and there was tumour involvement in all the spleens removed. Two patients died from septicaemia, the one before splenectomy and the other 9 months after the operation. The 8 remaining patients have had their subjective symptoms alleviated and their peripheral blood indices have been improved by splenectomy, and none has required further treatment for periods now ranging from 7 to 41 months.

In a retrospective study of 38 patients with histologically proven myelofibrosis, 5 parameters (recorded on the first admission) were investigated as to their usefulness to predict the course of the disease. In 9 patients the development of 'acute' myelofibrosis could be predicted by the finding of pancytopenia, low reticulocyte counts (median 20,500/mul), extremely elevated SRE (median 125 mm) and normal serum levels of LDH and uric acid on the first admission. In 28 patients the development of classic fibrosis with splenomegaly could be predicted by the finding of high reticulocyte counts (median 133,200/mul) and increased levels of serum LDH (median 547 U) and uric acid (median 8 mg/dl in males and 6.8 mg/dl in females) on the first admission, even when splenomegaly was initially absent. The relationship between classic and acute myelofibrosis and the significance of the mentioned parameters is discussed.

A 22-year-old man with fever, hepato-splenomegaly and severe pancytopenia is described in whom the histologic features of the spleen, liver and lymph nodes were consistent with malignant histiocytosis. Characteristic Leishman-Donovan bodies were demonstrated on a bone marrow aspirate, and the diagnosis of visceral leishmaniasis was confirmed by culturing the flagellated forms of the pathogen, and by an excellent response to sodium stibogluconate. In view of the similarity in clinical and histologic appearance, visceral leishmaniasis must be considered in the differential diagnosis of malignant histiocytosis in geographic areas where leishmaniasis is still endemic.

Hypersplenism is characterized by cytopenia, splenomegaly (possibly hyperplastic bone-marrow), and lienal hypersequestration. It is necessary, in view of the rather important surgical risks of splenectomy, to clarify if the hypersplenism may be influenced by splenic irradiation in case of chronic myeloid leukemia (CML) or chronic lymphatic leukemia (CLL). References in literature are rare and do not present a reliable differentiation of the syndrome, according to its present definition. Of our patients, three cases with hypersplenism verified by radioiron studies are reported: in one patient with chronic myeloid leukemia, irradiation of the spleen had no effect, whereas pancytopenia was completely repaired by means of splenectomy. The same results were seen in a patient with chronic lymphatic leukemia. In the last patient, however, who had chronic lymphatic leukemia, fractionated irradiation of the spleen led to a distinct improvement of anemia and thrombopenia, but the recovery lasted only six months. This effect is due to transient normalization of the lienal hypersequestration.

This study is based upon an analysis of the hematologic and pathologic material from seven patients with acute myelosclerosis, as well as a review of the literature of 49 cases reported under this designation, or one of its synonyms. Patients with this disease characteristically present with pancytopenia, minimal or absent anisocytosis and poikilocytosis, and a fibrotic bone marrow showing hyperplasia and immaturity of all three cell lines, with particular prominence of megakaryocytes and their precursors. In addition, clinical splenomegaly is almost always absent, and the disease has a rapidly fatal course. We consider only one-fourth of the cases reported in the literature to have the clinical and hematologic features consistent with the diagnosis of acute myelosclerosis; the remainder represent a variety of myeloproliferative disorders, including chronic myelosclerosis with an accelerated terminal phase, acute myeloblastic leukemia with bone marrow fibrosis, myeloproliferative diseases that cannot be subclassified, and cases in which the data are insufficient for analysis. Using strict clinical and hematological criteria, acute myelosclerosis can be separated from other myeloproliferative disorders as a distinct clinicopathologic entity.

A 65-year-old woman had pancytopenia, splenomegaly, and an inaspirable bone marrow. Diagnostic evaluation demonstrated that she had both leukemic reticuloendotheliosis (LRE), or hairy cell leukemia, and an additional lympho-reticular neoplasm, most likely a "histiocytic" lymphoma. The diagnosis of LRE was based on the histopathology of spleen tissue and of a bone marrow biopsy specimen. The diagnosis of diffuse "histiocytic" lymphoma was based on the histopathology of a splenic hilar and a mesenteric lymph node, tumor nodules in the kidney and spleen, and tissue from a mass obstructing a ureter. This is the first well-documented association of a second lympho-reticular neoplasm with LRE. Even relatively gently treatment of the "histiocytic" lymphoma resulted in fatal pancytopenia, illustrating the restricitons on therapy imposed by the marrow impairment due to the LRE.

A patient with gamma heavy chain disease (Franklin's disease) was discovered during evaluation for pancytopenia and splenomegaly. Lymphadenopathy, palatal edema, and infiltration of the bone marrow palatal edema, and infiltration of the bone marrow with abnormal cells were all absent. Serum and urine protein electrophoresis demonstrated a monoclonal protein migrating in the beta region. Immunoelectrophoresis showed that it reacted with antibodies against the Fc fragment of IgG heavy chains (gamma chains) but not with antibodies against kappa and lambda but not with antibodies against kappa and lambda light chains of Fab fragments. In the first year after detection of the disease, the patient had acute cholecystitis and disseminated herpes zoster. Sixteen months after diagnosis he died of overwhelming pneumonia caused by Pseudomonas aeruginosa and lebsiella neumoniae. A striking feature of his illness was his asymptomatic presentation, with pancytophenia and splenomegaly the only indication of this disease.

The experience of the University of Colorado Medical Center affiliated hospitals with leukemic reticuloendotheliosis, hairy cell leukemia, during the past two years has been reviewed. Eight instances were found. The majority of patients in this study presented with fatigue, pancytopenia and splenomegaly. Diagnosis was based upon finding characteristic hairy cells in the blood, bone marrow or spleen. Treatment, unlike other hematopoietic malignant conditions, was primarily surgical, with splenectomy being the treatment of choice, which may lead to prolonged remission in the majority of instances.

Chronical course, splenomegaly and pancytopenia are characteristic for hairy cell leukemia. The main feature are so-called hairy cells in peripheral blood. This cells were investigated by cytological, cytochemical, histological and electron microscopical methods. Special cytoplasmic inculsions seem to be specific for this cell type.

A 53-year-old dock labourer, presented with massive splenomegaly and subsequently developed pancytopenia. Complete haematoglogical remission was observed following splenectomy. Histological examination of the liver and spleen revealed sarcoid granulomata. A year after splenectomy, he died in an acute haemolytic crisis, a very rare complication of sarcoidosis. Evidence of generalized sarcoidosis was found at autopsy. The literature on haematological complications in sarcoidosis is reviewed.
