Results: There were 2 males and 1 female among the patients diagnosed with thoracic cage or pulmonary amyloidosis. The patients were 67-84 years old and had no history of previous malignancy. Clinically, either lung cancer or sternal osteochondroma was suspected. Radiologically, 1-2 nodules measuring 1.5-9.0 cm were found in lungs (2 cases, one of these being bifocal) or sternum (1). Surgical treatment was applied in all cases. Amyloid deposits were identified by Congo red stain and polarisation microscopy. AL type of amyloid was confirmed. In case of bone lesion, the plasma cells were monoclonal justifying the diagnosis of multiple myeloma. Conclusion: Localised amyloidosis can involve lung or sternum as tumour-like mass. The lung lesions can be single or multiple. Association with haematologic neoplasm is likely if bone is affected. Clonality analysis of plasma cells surrounding amyloid deposits is mandatory.
