Abstract

Pulmonary amyloid deposition generally occurs with concurrent primary systemic amyloidosis. Localized forms of pulmonary amyloidosis are rare and appear most frequently as an incidental finding on chest radiographs. We present a case of nodular pulmonary amyloid tumor suggested by fine needle aspiration cytology (FNAC) and confirmed by histologic examination with the polarizing light microscopy. A 41-year-old woman presented with ill-defined nodules in the middle and lower lobes of both lungs. FNAC of the nodules revealed waxy, acellular amorphous fragments. Thoracotomy for diagnosis may be avoided by FNAC diagnosis of this unusual lesion.
