[Post-transplantation of Hodgkin's disease. Clinico-pathologic study of 3 cases].

As a frequent complication of immunosuppression, lymphoproliferative disorders affect approximately 2 % of allorgan transplant recipients. Most of them are EBV-associated-B-cell-lymphoproliferations. Other types of non Hodgkin's lymphomas and Hodgkin's disease, as observed in general population, have only rarely been reported in this group of patients.

[Cystic mucinous pulmonary tumor of borderline malignancy. Report of a case].

A cystic mucinous borderline tumor was discovered in a sixty two year old man, presenting as a cystic mass in the right lower lobe. A first diagnosis of bronchiolo-alveolar carcinoma was made on bronchial biopsies. Surgical specimen examination revealed a lung mucinous cystic borderline proliferation similar to ovary borderline mucinous tumors.

[Acute and reversible interstitial granulomatous nephropathy after treatment with captopril].

Angiotensin-converting enzyme inhibitors (CEI) have been found effective in numerous cases of arterial hypertension, even non renovascular, and they are now widely used. However, the reference compound, captopril, has exhibited various side-effects, including acute renal failure. Different mechanisms may be responsible for this complication.

[Reversible acute renal failure with tubular oxalosis. Possible role of nutritional factors].

Intratubular deposits of calcium oxalate crystals can be responsible for acute renal failure. The present report concerns two cases for which none of the known causes of oxalate nephropathy were found. Both patients had common features: chronic alcoholism and denutrition.

[Prognosis of hemolytic uremic syndrome in children. Importance of extrarenal involvement].

The prognosis of hemolytic uremic syndrome was studied in 37 children hospitalized between January 1980 and January 1985. 75% of affected children were less than 3 years of age. Twenty-two (60%) presented with anuria or oliguria (mean duration of anuria: 10.

[Osteomedullary amyloidosis with osteolytic lesions. Apropos of 4 cases].

Amyloidosis of bone and bone marrow is rarely symptomatic and is generally limited to deposits diagnosed by histological examination. Four cases with lytic bone lesions are reported. In 2 cases, amyloidosis was associated with Waldenstroem's Macroglobulinemia, in one case with multiple myeloma and in 1 case with solitary plasmocytoma.

[Silicone deposits in macrophages of patients on chronic hemodialysis].

A retrospective study was carried out in search of silicone deposits in 11 periodic hemodialysis patients (1 liver biopsy, 4 splenectomies and 6 autopsies) treated between 12 and 60 months with equipment containing a silicone pump segment. Silicone particles were found in the macrophage cells of all patients, especially in the liver and spleen, but also in lymph nodes, bone marrow and even an artery wall. In some cases, macrophage response had formed sarcoid-like granulomas.

[Anatomo-clinical correlations in Berger's disease: evaluation of the prognosis by analysis of one hundred and one cases (author's transl)].

In order to evaluate the prognosis of IgA nephropathy semi-quantitative analysis of tubulo-interstitial and vascular alterations was performed. Three groups of patients are described. In the first group the prognosis has remained favourable until the present time.

[Acute agranulocytosis after treatment by levamisole. 2 cases (author's transl)].

We describe two patients who had a typical levamisole-induced agranulocytosis and a severe infection; the view of other cases found in the literature shows a fundamental fact: the complication can occur after a variable time of prescription (from thirteen days to eleven months), continuous or intermittent. The accidents are imprevisible, and circonspection must be used, not for its antihelminthic properties, but for its prolonged use for immunological purposes, even if some authors have not observed any cases of agranulocytosis in large series. Naturally, the purpose is quite different in the case of a severe rheumatoid arthritis or inesthetic warts, and our two observations are very demonstrative.
