Introduction: Pulmonary nodular amyloidosis (PNA) is a phenomenon that is rarely diagnosed anywhere in the world.
Methods: We report a case of a 63-year-old woman who smoked in whom a chest X-ray examination 5 years after diagnosis and radical treatment of a highly differentiated carcinoma of the corpus uteri showed multiple lung metastasis. To elucidate these findings by bronchoscopy and thoracoscopy we took a specimen from the right pleura and from one of the suspicious nodules, which were up to 3 cm in diameter; we also obtained some of the bronchial secretion.
Results: The nodules were histopathologically diagnosed as PNA.
Conclusion: Even if it is rare, PNA also belongs in the differential diagnosis of metastatic cancers. For us evidence of Pseudomonas fluorescens in the sputum is a reason for discussing a chronic, clinical unobtrusive local inflammation with hyperactivity of the B-cells as the hypothetical etiology of the amyloidomas.
