Three cases of congenital leukaemia associated with hydrops and intrauterine death are described. The leukaemic infiltrates, which involved both the infants and the placentas, were of monocytic, lymphoblastic, and myeloblastic types, respectively. The general lack of recognition of the condition is probably due to inadequate histological examination of the stillborn infant and the placenta.

The simultaneous detection of multiple myeloma and acute myeloblastic leukaemia is reported in two patients who had not undergone chemotherapy. Histological examinations confirmed the infiltration by both myeloblasts and plasma cells. Only the latter contained monoclonal immunoglobulin chains at immunofluorescent studies. The possible relation between the two distinct proliferative processes is...

Fourty-four patients with acute myeloblastic leukaemia were treated with RP 22050, a new, semisynthetic derivative of daunorubicin. Complete remissions were achieved in 20 patients (45%). The median dose given was 23 mg/kg. The toxicity of RP 22050 is mainly haematological. Resistance rather than death in aplasia seemed to be the cause of failure of therapy.

Two cases of visceral leishmaniasis (VL), one in a 51-year-old man with accelerated-phase chronic myeloid leukemia and another in a 35-year-old woman with acute myeloblastic leukemia, are reported. Incidental finding of Leishman-Donovan (LD) bodies in patients with leukemia highlights VL as a potent opportunistic infection in immunosuppressed patients.

A correlation was made between chromosomal findings in the marrow of AML patients obtained during the course of the disease, some of the clinical and cytologic features, and the survival span of these patients. The median survival time for each patient was obtained by the use of log-probability paper. Of the 69 patients with AML studied, 29 showed abnormal metaphases in the marrow at least once...
