A patient is described who has chronic granulocytic leukemia (CGL) and familial sarcoidosis, and who has been in complete remission for six years after a single course of busulfan therapy. Her bone marrow Philadelphia chromosome persists and the leukocyte alkaline phosphatase activity remains subnormal. Leukocyte alkaline phosphatase levels in nine white patients with sarcoidosis were all found to be low. Bone marrow chromosomes from two patients with active sarcoidosis showed no Philadelphia chromosome, but one of them, and our patient with CGL, exhibited a pericentric inversion of chromosome 9.

Sickle cell retinopathy, in all of its manifestations, represents the effects of arteriolar and capillary occlusions. Increased viscosity of circulating whole blood plus the microembolic action of individual sickled erythrocytes contribute to vasoocclusion. Decreased oxygenation and increased acidosis develop and lead to further sickling -- and further vaso-occlusion. The cycle of erythrostasis that characterizes sickling throughout the body is also applicable to the retina. The transparent media of the eye permit direct visualization of vaso-occlusions which occur preferentially in and about the macula and in the far periphery of the retina. Many of the occlusive episodes are transient. There dynamic events are simultaneously occurring elsewhere in the body but can only be visualized in the eye. The net effect in the retina is a remodeling of its vasculature, as some vessels close and others reopen. After the onset of arteriolar closure in the retina, affected blood vessels embark on a spontaneous, naturally evolving course of events leading to arteriolarvenular anastomoses, neovascular proliferations, vitreous hemorrhages, and retinal detachment. The advanced stages of proliferative sickle retinopathy are most commonly observed in SC disease and in Sthal, possibly because these two forms of sickling have significantly higher than normal whole blood viscosity. Retinal vaso-occlusions can also lead to blow-out hemorrhages which may evolve into salmon patches, iridescent spots, schisis cavities, and black sunbursts. In some respects sickle retinopathy is unique, but many of its manifestations are similar to those of retinopathies found in diabetes mellitus, AC hemoglobinopathy, Takayasu pulseless disease, sarcoidosis, chronic myelogenous leukemia, branch retinal vein occlusion, retrolental fibroplasia, and Eales disease.

Inv (1) antigen distribution was studied in 568 normal subjects and in 354 hematological patients in the Armenian population. Inv (1) antigen was detected in 16.7% of the normal Armenians studied. The incidence rate of Inv (1) factor does not depend on the distribution of phenotypes of ABO system, rhesus factor (D), and the sex of the subjects investigated. Inv (1) antigen incidence rate in patients with acute leukemia, chronic lymphocytic leukemia, iron deficiency anemia, lymphogranulomatosis, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia was similar to that in the control, and only patients with chronic myeloid leukemia had significantly decreased levels of Inv (1) antigen: 6.8% as compared to 16.7% in the population.

Microscopic and medical review of twenty-six patients with skin biopsy specimens that showed granulomatous vasculitis demonstrated vascular histiocytic granulomas with fibrinoid destruction of blood vessels in the dermis and panniculus. Cultures of the biopsy specimens were nonspecific. The skin lesions varied from erythema to papulonodular and vesicular eruptions; they were usually on the extremities but also involved the trunk. Eight patients had systemic lymphoproliferative diseases: three, lymphoma; two, angioimmunoblastic lymphadenopathy; two, preleukemia; and one, chronic granulocytic leukemia. Five of these eight patients died within 2 years after the onset of skin lesions. The four patients with systemic vasculitis died within 1 year after the onset of skin lesions. Five patients with arthritis, four with gastrointestinal disease, three with systemic sarcoidosis or sarcoidlike disease, and one with tuberculosis had a more favorable prognosis. The histologic pattern of cutaneous nonlymphomatoid granulomatous vasculitis is associated with significant systemic disease, especially lymphoproliferative disorders. Patients with lymphoproliferative disorders or systemic vasculitis have a much poorer prognosis than those with inflammatory or infectious granulomatous disease.

Focal granulomatous giant cell reticulosis was observed in lymph nodes from treated cases of chronic lymphatic and chronic myeloid leukaemia. On the basis of clinical behaviour and histological appearance, it seems plausible that in the terminal phase of leukaemia non-neoplastic reactive reticulosis developed very similar in appearance to lymphogranulomatosis. The possible relationship between malignant lymph node tumours, Hodgkin's disease, and leukaemia is discussed. Repeated biopsies from leukaemic patients would perhaps permit of further clarification of this process.

The group consisted of 1056 children with enlarged thymus and a monitored catamnesis in 317 of 0.5-23 years. In 5 examinations in different periods after the diagnosis of enlarged thymus, haematological malignancies were diagnosed: acute lymphoblastic leukaemia (2 children), lymphogranulomatosis (1 child), chronic myeloid leukaemia (monocytic variant) and histiocytosis of Langerhans (1 child). The comparison of these data with other publications on the prevalence of these diseases in the population and the rate of mortality in Moscow place the children with enlarged thymus to high-risk group for haematological malignancies.

Eosinophil leukaemia is a rare and poorly defined entity characterized by neoplastic proliferation of eosinophil cell line. This form of the hypereosinophilic state is considered to be a variant form of CML, although as a diseases entity is not generally accepted. A history of a patients is reported, whose clinical course is thought to fulfill the requirements of eosinophil leukaemia. On the basis of the initial results (pathological lymphogram, eosinophilia, Ph-negativity) lymphogranulomatosis was suspected and explorative laparotomy was performed. However, only marked eosinophilic infiltration of the spleen was detected. After splenectomy his disease was stable without treatment for six months when his leukocytosis and eosinophilia increased. Despite the administration of hydroxyurea the leukocyte count exceeded 100 x 10(9)/l (eosinophil cells 70%), and the bone marrow revealed massive (80%) eosinophilic infiltration. Neither Ph-chromosome, nor cabl and bcr gen rearrangement were demonstrated, but the expression and amplification of c-myc oncogene indicated disease progression. Interferon therapy produced long-term clinical and haematological improvement, but blastic transformation was developed in the second year of his disease. Autopsy showed multiple organ involvement characteristic of CML, but no marked eosinophilic infiltration was found. The feature of this case suggest that eosinophil leukaemia might represent an uncommon form of Ph-negative CML.

The efficiency of a diagnostic procedure is evaluated by the percentage of subjects accurately identified, as either suffering from the disease looked for (true positive, TP) or not (true negative, TN). Sensitivity and specificity are the percentage of TP or TN, respectively, accurately identified. Cytological diagnosis of Hodgkin's disease (HD) was evaluated; smears were made from fine-needle aspiration. One hundred and nine smears were examined independently by two cytologists; adenopathies were benign in 43 cases (tuberculosis 25, non-specific reactive hyperplasia 16, sarcoidosis 2) and malignant in 66 cases (HD 36, Non-Hodgkin's lymphoma 22, malignant histiocytosis 2, metastasis 5, blast crisis of chronic myeloid leukemia 1). Benign and malignant diseases were diagnosed by lymph node biopsy; diagnosis of HD was made in 36 TP patients; the 73 others are TN. Sensitivity, specificity and efficiency are: 75, 90.4, 85.3, respectively for one observer; 77.7, 91.8, 87.1 respectively for the other: 63.8, 90.4, 81.6 respectively when diagnosis was the same for the two cytologists. Fine-needle aspiration permits the diagnosis of HD in eight out of 10 cases; it is useful when biopsy is difficult or too expensive, as is often the case in developing countries.

A 79-year-old man who had been diagnosed as having sarcoidosis when he was 63 year old, was admitted to our hospital because of marked thrombocytosis and leukocytosis in July 1991. The low neutrophil alkaline phosphatase (NAP) score, presence of Philadelphia (Ph1) chromosome in the bone marrow cells, and M-BCR rearrangement by Southern blot hybridization were observed. He was diagnosed as having chronic myelogenous leukemia complicated with sarcoidosis. The coexistence of sarcoidosis and leukemia has rarely been reported. It is difficult to discuss that there is not causal association between of them.

A patient with Philadelphia-positive (Ph+) chronic myelogenous leukemia (CML) was diagnosed with cutaneous sarcoidosis after treatment with interferon-alpha (IFN-alpha). Following IFN-alpha dose reduction, the skin lesions disappeared. Few cases of sarcoidosis associated with IFN treatment have been reported, and only in one patient with pre-existing CML. Our patient was unique in that (1) the sarcoidosis was induced by the IFN-alpha treatment alone, (2) it developed de novo, and (3) it was confined to the skin.
