Ultrastructural features in an erythrophagocytic T4 lymphoma.

Electron microscopic investigation allowed the identification and characterization of the atypical malignant cells in a case of T-cell lymphoma. The proliferating cells were endowed with characteristics belonging to two different lineages: phagocytic ability, complement receptors and ultrastructural features proper to the macrophagic lineage, and T-cell determinants (E receptors, T3, T4 and T11 antigens). The cells were peroxidase and esterase negative. The erythrocytes were partially or completely dehemoglobinized and presented the phenomenon of autolysis in different stages of evolution. Because this lymphoma is difficult to diagnose and is apparently resistant to therapy, its recognition and further study are warranted.

Introduction to the study of adult T-cell leukemia and HTLV-I sero-positivity in Romania.

The study presents 6 cases of leukemia/lymphoma (with mature T-cells) corresponding to the diagnostic criteria of adult T-cell leukemia (ATL): adult age onset of leukemia/lymphoma, organomegaly but normal mediastinum, leukemic cells with typical morphology and phenotype hypercalcemia. The evolution of disease was severe of subacute with resistance or partial response to therapy. The virologic assays were positive according to the ELISA test in four cases of which two presented, according to the Western blot assay, HTLV-I infection. The epidemic aspect of this infection is discussed as well as the possibility of contamination and the geographic spread of the places of origin of the patients. Emphasis is laid on the young age (22-26 years) of three of the patients infected, as a peculiar feature of the disease in Romania.

Autoimmune hemolytic anemia with warm antibodies complicated with an intercurrent attack of hemolysis with cold agglutinins in a case of Waldenström disease.

The paper presents a case of autoimmune hemolytic anemia (AIHA) with warm IgG antibodies associated with Waldenström's disease in which in the stage of compensated hemolysis after treatment, there appeared a severe hemolytic attack induced by transitory cold agglutinins with high thermal amplitude. The case described is a novelty by the intrication of two autoantibody populations which causes autoimmune hemolysis. The difference from other similar associations is discussed.

[A case of disseminated intravascular coagulation--a paraneoplastic manifestation of a borderline ovarian tumor].

A 24-year-old-woman was admitted because of disseminated intravascular coagulation (DIC), menometrorrhagia and galactorrhea. The investigations performed showed a right adnexal tumor after the equilibration of DIC with plasma substitution, we performed a right adnexectomy with limited excision of peritoneal. The pathologic examination showed a focus of endometriosis on the right ovary who had a polycystic look and a right adnexal fibromyxoma (premalignant lesion). The post operative evolution was good, with the loss of entire onco-hemato-endocrinologic picture. We describe the interrelation between DIC (paraneoplastic syndrome), menometrorrhagia and galactorrhea, the pathologic hypothesis and the treatment of DIC.
