Bronchiolar adenomatosis. A case report

A case of bronchiolar adenomatosis (benign pulmonary adenomatosis) with unusually widespread pulmonary changes is presented. This disease is rare and occurs equally in both sexes. The tumourous growth is slow and can easily be mistaken for alveolar cell carcinoma, alveolar proteins, tuberculosis, sarcoidosis, or malignant pulmonary adenomatosis. The diagnosis can be made on a histological specimen from the affected lung. In spite of a benign histological picture, the disease may ultimately run an unfavourable course because of its malignant potentialities. A distinction between benign and malignant pulmonary adenomatosis may therefore only be made with certainty by a complete and careful postmortem examination.
