Specific cutaneous manifestations of Waldenström's macroglobulinaemia. A report of two cases.

Patients affected by Waldenström's macroglobulinaemia may rarely present specific cutaneous manifestations. The violaceous plaques or tumours infiltrated by lymphoplasmocytoid cells, and the pink, translucent, shiny papules composed of deposits of hyaline monoclonal IgM possess definite clinico-pathological characteristics that may permit the diagnosis before any other data were available. The immunopathological and ultrastructural features of these lesions are described.

Tumour lysis syndrome with hypocälcaemia in accelerated chronic granulocytic leukaemia.

Tumour lysis syndrome is a well-known complication of lymphoid malignancies, but it has rarely been described in myeloproliferative disorders. A patient is reported with myeloblastic type of accelerated chronic granulocytic leukaemia who developed a tumour lysis syndrome following intensive chemotherapy. The most prominent manifestation of such a syndrome was hypocalcaemia, which was associated with other biochemical alterations, including hyperphosphataemia, hyperuricaemia and renal failure.

Prognosis of chronic lymphocytic leukemia: a multivariate survival analysis of 150 cases.

A multivariate survival analysis by means of Cox's multiple regression model was performed on a series of 150 consecutive patients with chronic lymphocytic leukemia (CLL) from a single institution. In addition to the well established prognostic factors, such as anemia and thrombocytopenia, a marked prognostic value of the degree of absolute peripheral lymphocytosis emerged from this analysis. This was evident in the whole population as well as in low and intermediate risk groups of patients (Rai's stages 0, I, and II and International Workshop on CLL stages A and B), pointing out that different subsets of patients can be isolated within these groups.

Prognostic significance of bone-marrow patterns in chronic lymphocytic leukaemia.

Bone-marrow biopsy has been performed in 63 cases of chronic lymphocytic leukaemia (CLL). Four different histological patterns were observed: (a) interstitial (lymphoid infiltration without displacement of fat cells) in 12 cases; (b) nodular (abnormal lymphoid nodules without interstitial infiltration) in 10 cases; (c) mixed (combination of the first two patterns) in 21 cases; and (d) diffuse (replacement of both haemopoietic and fat cells by lymphoid infiltration) in 20 cases. Statistical analysis of actuarial curves showed a significant difference of survival probability according to the bone marrow infiltration patterns. Thus, in patients with interstitial or nodular patterns the life expectancy is significantly longer than in those with mixed or diffuse patterns. furthermore, a significant degree of correlation between bone marrow infiltration patterns and different methods of clinical staging in CLL was apparent. The different bone marrow infiltration patterns in CLL probably reflects variations in the amount of lymphoid accumulation during the natural course of this disease. Because of its prognostic significance, bone marrow biopsy should have a place in CLL evaluation and staging.

Multiple myeloma in primary biliary cirrhosis.

A patient who had primary biliary cirrhosis and, simultaneously, multiple myeloma (IgG, lambda) is reported. In chronic liver diseases, polyclonal hypergammaglobulinaemia is common, monoclonal gammopathies have also been found in rare instances, being attributed to chronic antigenic stimulation of the reticuloendothelial system by antigens from the intestinal flora. The mechanisms (as chronic antigenic stimulation, immunologic disturbances and granulomata formation) which apply to explain the development of monoclonal gammopathies in other conditions are also found in primary biliary cirrhosis. It is postulated that, in this disease, the development of multiple myeloma could be not merely coincidental but also the result of chronic stimulation of the reticuloendothelial system.

Prognosis in acquired aplastic anaemia. A multivariate statistical analysis of 80 cases.

Prognostic factors were studied in a series of 80 patients with aplastic anaemia. The most important and easily obtainable individual variables, isolated in a previous univariate statistical analysis, were placed in a linear logistic regression model. A prognostic formula was derived containing the following 4 variables, in decreasing order of significance: (1) reticulocytes, (2) interval from onset of symptoms to first visit, (3) mean red cell volume, and (4) platelets. The prognostic formula permits an estimate of the probability of death within 3 months from the first visit. Its usefulness in several clinical situations, especially those related to bone marrow transplantation, is illustrated.
