    Abstract:
    BACKGROUND: Aspergillus is a common cause of invasive mycosis, especially in immunocompromised or immunosuppressed individuals. AIMS: To study the incidence of invasive pulmonary aspergillosis and evaluate the predisposing factors and clinico-pathological manifestations. SETTINGS AND DESIGN: Retrospective analysis of autopsy material from a tertiary care hospital. MATERIAL AND METHODS: All autopsies performed over a 12-year period were reviewed and cases with invasive aspergillosis were analysed with respect to their clinical presentation, predisposing factors, gross and histological features, complications and causes of death. RESULTS: Among a total of 20475 autopsies performed in 12 years, 39 patients (0.19 %) had invasive pulmonary aspergillosis. There were 28 males and 11 females. Their ages ranged from five months to 67 years. Dyspnoea, fever, cough with mucopurulent expectoration, chest pain and haemoptysis were commonly encountered symptoms. Forty-one per cent of the patients had no respiratory symptoms. Fungal aetiology was not entertained clinically in any of the patients. The major underlying conditions were prolonged antibiotic therapy, steroid therapy, and renal transplantation, often associated with underlying lung diseases. Pneumonia, abscesses, vascular thrombosis and infarction were common findings at autopsy. Antecedent tuberculosis, mucormycosis, Pneumocystis carinii pneumonia and Cytomegalovirus infection were also present. In most cases, death was related to extensive pulmonary involvement or fungal dissemination. CONCLUSION: A diagnosis of invasive pulmonary aspergillosis should always be borne in mind whenever one is dealing with recalcitrant lung infections even with subtle immunosuppression. Radiological investigations and serologic markers can be utilised for confirmation and prompt therapy.
