Malignant histiocytic lymphoma with large lacunar cells.

A case of lymph node biopsy with a peculiar histological aspect is described. The clinical data suggest a malignant lymphoid disease. The histological picture is that of a malignant histiocytosis but, among the majority of small histiocytes, there are some large cells like the large lacunar cells from Hodgkin's disease.

Pathology of lymph nodes in human immunodeficiency virus (HIV) infection.

The actual knowledge concerning the main physiological and histological data of AIDS are presented. The pictures are of lymph node biopsies from patients with AIDS, admitted in the Clinic of Hematology, Fundeni Hospital, Bucharest.

Chronic lymphocytic leukemia and Hodgkin's disease in the same patient: a report of two cases.

Two cases with coexistent chronic lymphocytic leukemia and Hodgkin's disease are reported. The first appeared disease was the chronic lymphocytic leukemia. The eventual influence of this disease on the development of the Hodgkin's disease is discussed.

A particular case of large granular lymphocytes lymphoma.

A patient with non-cutaneous lymphocytic lymphoma with leukaemic spread is reported. The large majority of the peripheral blood mononuclear cells formed rosettes with sheep erythrocytes (E), had receptors for the Fc portion of IgG (Fc gamma R) and displayed an unusual enzymatic profile. Part of these cells had also labile bound surface membrane IgG.

The "large cell" malignant lymphomas. A retrospective morphological analysis.

A series of 69 cases of "large cell" non-Hodgkin's malignant lymphomas is reviewed. Based only on morphological criteria, eight groups of such lymphomas are described: four of them with a highly reproducible diagnosis and other four more difficult to compare with categories described by other authors. The importance of morphological classifications of malignant lymphomas is discussed.

Study of mediastinal and lung involvements in Hodgkin's disease.

Clinical, biological, radiological and radioisotope investigations in 224 patients with Hodgkin's disease revealed a great frequency (100 cases, i.e. 44%) of mediastinal and pleuro-pulmonary involvements, most of them in advanced stages of the disease.

[Contrast medium persistence in lymph nodes as a prognostic criterion in Hodgkin's disease (author's transl)].

The persistence of contrast medium in the inguinal and retroperitoneal lymph nodes was observed in 104 cases of Hodgkin's disease. Systematic observations were continued until the contrast medium had disappeared completely. The maximum period of observation was 36 months.

Relationships between lymphography and the histologic nodal and splenic types in Hodgkin's disease. Considerations on clinical evolution.

Trying to establish the eventual interrelations of the initial histologic nodal type and the splenic one, the general lymphographic picture, the histologic nodal type and spleen involvement, lymphographic and histologic examinations were carried out in 151 patients with Hodgkin's disease. Lympographies were performed in 139 cases, and splenectomy (followed by splenic, hepatic and abdominal lymph node biopsies) in 32. Lymphocyte depletion was found in 72.

Comparative cytogenetic and cytologic study in malignant lymphomas.

The possibility of a cytogenetic-cytologic correlation with implications in the diagnosis, evolutivity and prognosis of malignant lymphomas was studied. Cytogenetic investigations were carried out comparatively in the lymph node and spleen lymphoid cells from 25 patients with malignant lymphomas and in normal subjects or patients with malignant tumors. The dominant malignant cellular type was found to correspond genotypically to the abnormal clone.

Screening tests for the enzymatic diagnosis in liver diseases and myocardial infarction.

To perform the ever increasing number of analyses with a minimum equipment the tendency all over the world is now to replace the classical tests with screening tests. The laboratory of enzymology of the Institute of Internal Medicine has achieved screening tests for the estimation of alkaline phosphatase, of total lactatedehydrogenase and of its fraction I, whose results are in agreement with the reference methods of Bessy-Lowry-Brock and of Lac-Dehystrate-Goedecke in cases of acute and chronic liver diseases, neoplasms, bone diseases (Paget's disease) and myocardial infarction.

Clinical evolution, histologic type and general lymphographic picture in Hodgkin's disease.

In 88 patients with Hodgkin's disease the clinical value of the general lymphographic picture (lymphodynamic aspects plus nodal patterns) is analysed. The survival times are also reported according to the different pre- and postlymphographic evolution. Histologic types and prelymphographic therapy are correlated with the general lymphographic picture.

Lymphographic aspects of the barrier function of lymph nodes in Hodgkin's disease.

The persistence of Lipiodol in various lymph node groups was followed up by systematic lymphographic control. Assuming a certain relationship between the barrier function of the lymph nodes and the persistence of their image on the film the authors have tried to find out whether the duration of Lipiodol persistence may be a test for the estimation of prognosis in Hodgkin's disease. The observation of such cases has shown that Lipiodol is retained for a longer period in the external iliac and lombo-aortic lymph nodes as well as in the pathologic ones, except those with lymphocyte depletion, whereas it is very rapidly eliminated from the inguinal nodes.
