We conducted prospective, descriptive type of study in 300 consecutive autopsy cases   over a span of two years. Out of 300 autopsy cases, lung lesions were encountered in 270 cases. benign lesions outnumbered malignant lesions. Pulmonary oedema was the most frequently encountered lesion followed by alveolar hemorrhage both of which usually represent the terminal end stage disease. Infectious causes like pneumonia and tuberculosis were the next culprits. Tuberculosis is a notorious infection not only in Indian community, but also worldwide. It is especially important due to its association with AIDS. Rare cases of disseminated infection with Cryptococcosis, candidiasis, microfilaremia as well as sickle cell disease can be a cause of death.
