The great strides in organ transplantation have been accompanied by some specific pathologies, notably, neoplasia, including Kaposi's sarcoma which occupies the third place in frequency after cutaneous tumours and malignant lymphomas. We report a case of cutaneous Kaposi's sarcoma developing some six months after a cardiac transplant. The modulation of immuno-suppression and treatment with Alpha interferon allowed an initial stabilisation of the cutaneous lesions. However, there were secondary developments of the lesions and, 21 months after the initial presentation, the patient developed a diffuse infiltrating pneumonia leading to death. The autopsy revealed lymphangitis carcinomatosis of Kaposi's sarcoma type. This observation underlines the therapeutic difficulties seen in Kaposi's sarcoma after organ transplantation when there is no alternative to allow a significant reduction or cessation of immuno-suppression.

Iatrogenic pneumonias to sulphasalazine are most usually seen during the course of a haemorrhagic proctocolitis (RCH). We report a case in which a young woman was treated with 5-aminosalicylate (Pentasa) and prednisolone during an exacerbation of RCH. After 3 months of treatment the steroid therapy was stopped and the Pentasa was continued at the same dose (3 g per day). She presented with increasing dyspnoea on effort. Clinical examination was normal but a CT scan of the chest showed interstitial micro nodules; there was also a restrictive ventilatory disorder, hypoxaemia on effort and an alveolar eosinophilia (1.8%) The clinical progress, respiratory and blood gases all improved rapidly after stopping the Pentasa with the disappearance of the interstitial nodule over 5 months, suggesting that the role of the Pentasa was causal in the genesis of the pneumonia.

We report a case of pulmonary malakoplakia in a patient suffering from AIDS secondary to a Rhodococcus equi pneumonia. The association between these two pathologies only occurring in the immunodepressed does not seen fortuitous. Deficiency in cellular immunity and macrophage cellular activity as well as failure of intracellular bactericidal and phagolysosomal function are very probably the links. The treatment of this opportunistic germ rests on prolonged poly-antibiotic therapy or indeed surgical excision.

Cough is known to be the major respiratory side effect of treatment with angiotensin converting enzyme inhibitors (ACEI). Recently, ACEI have been implicated in drug-induced lung disease. We report a new case of diffuse pneumonitis which occurred during treatment with ACEI. A 73-year-old man was admitted for cough, dyspnea at rest, fever and weight loss. The patient had been treated with the ACEI pirindopril during 6 months for systemic hypertension. Chest radiographs showed reticular infiltrates in the upper lung fields. A CT scan confirmed the infiltrates and showed pleural thickening and airspace opacities. White blood cell counts showed 15,700/mm3 leucocytes with 940 eosinophils/mm3. Transbronchial biopsy was consistent with infiltration of the lung with eosinophils. There was no evidence for another etiology. Once the drug was withdrawn, clinical and radiological abnormalities improved but steroids were required to control symptoms. This report suggests that pirindopril, as captopril, can induce the picture of drug-induced pulmonary disease.

Chronic eosinophilic pneumonia (CEP) was described by Carrington in 1969. It is twice as common in women as it is in men and is probably most common at middle age. Symptoms usually associated fever, weight loss, fatigue and dyspnoea. Extra-respiratory manifestations are rare but may involve many organs. Classical radiological findings are diffuse alveolar infiltrates, with a peripheral predominance which explains the classic description of a "negative of pulmonary edema". Peripheral blood eosinophilia is present in 90%. The inflammatory syndrome with an eosinophilic alveolitis is constant. Pulmonary function tests show a restrictive pattern with depressed DLCO and hypoxemia. In atypical cases, proof of diagnosis is supported by lung biopsies that show intra alveolar and interstitial accumulation of eosinophils in peripheral air spaces. Areas of bronchiolitis obliterans are also frequently seen. In some atypical forms of chronic eosinophilic pneumonia, other disorders have to be discussed, like bronchiolitis obliterans with an organizing pneumonia or cryptogenetic organizing pneumonia and even tuberculosis. After corticosteroid therapy, the resolution occurs very rapidly but relapses are frequent. Steroid-dependence is seen in 20 to 30% of patients.

Invasive pulmonary aspergillosis (API) is a necrotising pneumonia generally occurring in profoundly immunodepressed subjects. These observations were based on four patients in the intensive care unit, suffering from chronic respiratory failure (IRC), without profound immunodepression. After a pathophysiological and clinical review, a focus on the diagnostic methods permits one to stress on the reliability, in this type of patient, of the evidence from direct examination of aspergillus filaments in the bronchoalveolar lavage (LBA) or protected bronchial brushings, taking account of the weak value of routine culture of spit or bronchial aspiration in IRC in whom patients are frequently colonised. These four cases permit one to discuss the factors which predispose to the development of API outside the usual immune suppression: IRC itself, by the disorder of mucociliary function, which it leads to; repeated antibiotic therapy which destabilises the saprophytic flora; viral infections which would be responsible for transitory immunodepression. But it is above all steroid therapy which seems to be the major factor favouring the development of API without producing profound immunodepression but probably because it inhibits phagocytosis of aspergillus spores. In these circumstances it is necessary to make an early diagnosis and to use fibre optic bronchoscopy with protected sampling and bronchoalveolar lavage with a complete microbiological. Only early treatment allows one to contemplate a cure.

We report the case of a patient who was admitted to hospital for a pneumonia in association with a Stevens-Johnson syndrome. The association of these conditions suggested a Mycoplasma pneumoniae infection, which was confirmed on serology. There were three other extra-respiratory complications discovered: cold agglutinins, a disturbance of liver function tests, and circulating anticoagulant; both the two latter and the Stevens-Johnson syndrome are rare complications.

A case of toxic pneumonia due to busulfan is reported in a man aged 65 treated for three years with busulfan for chronic myeloid leukaemia. He was admitted to hospital for dyspnoea, cough, fever and presented with crepitations, dense alveolar opacities, and a restrictive ventilatory defect. Trans-bronchial biopsy showed a filling of the alveoli by fibroblastic tissue, as well as voluminous dystrophic pneumocytes. Four months later in spite of steroid therapy the clinical state and respiratory function were worse. The alveolar opacities have regressed but some diffuse interstitial opacities had appeared. This new case is a reminder that the appearance of alveolar opacities in a patient treated with busulfan should raise the possibility of a toxic pneumonitis to busulfan in the differential diagnosis. This observation also underlines the role of the initial endo-alveolar fibrosis in the ultimate development of interstitial fibrosis.

A young man without any past history of note had taken isotretinoin for disfiguring acne before the summer season. He presented with a severe bilateral pneumonia, associated with dyspnoea two months after the start of treatment. On the pulmonary radiography there was a bilateral ground glass appearance which was worse on the right. The elevated level of eosinophils (54% in 564,000 cells/ml) in the alveolar lavage lead to a diagnosis of allergic pneumonia. The rapidly favourable outcome following the cessation of the medication and with the addition of corticosteroids seemed to us a supplementary argument in favour of a diagnosis of eosinophilic pneumonia, due to isotretinoin which seemed the primary initiating factor.

Iatrogenic lung disease in man is generated by very different and often complex pathology. This explains the great clinical diversity of these disorders which may manifest as eosinophilic pneumonia, intra-alveolar haemorrhage, bronchiolitis obliterans and diffuse interstitial pneumonia even with pulmonary fibrosis. The causes are also very varied such as direct cellular toxicity, cellular oedema, an alteration of the alveolar capillary membrane, the activation of inflammatory and/or immune cells, which are responsible for the production of soluble mediators whose effects are sometimes harmful to the pulmonary parenchyma. Rather than reporting on the different clinical types of iatrogenic lung disease and indicating for each one the hypothetical or known physiopathogenic mechanism, we have chosen to examine certain fundamental lesional mechanisms and to indicate the principal nosological groups which they cover. We have centered this review on the physiopathogenic models which are the most coherent and most fully elaborated based on observations made on man or on experimental animal models. Among those we have reported here is a case of bleomycin toxicity, with its direct toxic mechanism on the epithelial or endothelial cellular targets, amiodarone lung disease and with its associated alveolar oedema, inflammatory reactions and immunological reactions whose specificity is poorly understood; also there are some alveolitides whose specificity has been demonstrated, such as those to minocycline and to BCG and finally a complex model which is both inflammatory and disturbed immunology in radiation pneumonia.
