| Abstract | A case of tobacco-associated pulmonary fibrosis, with the results of histological, ultrastructural, and spectrometric analysis is reported. Abnormalities of the alveolar macrophages, which are particularly affected by tobacco inhalation were found. The size of the macrophages was increased and many large, polymorphous inclusions, including fat vacuoles and granular deposits, which were either homogeneous or electron lucent vacuoles, were seen in the cytoplasm. A few laminar structures were observed. All of these lesions are frequently found in cigarette smokers. Still more interesting was the discovery of numerous fiber-, needle-, or laminar-like inclusions that varied in size from 0.2 to more than 2 mu. The digestions of the inclusions with potassium hydroxide confirmed the presence of various metals, such as sodium, magnesium, potassium, iron, sulfur, and especially, aluminum, and silicon; these last two elements correspond to the presence of kaolinite in the tissue, as has been previously described, and can be considered as evidence of the use of tobacco. |
