Pulmonary amyloidoma. Histologic proof yielded by transthoracic coaxial fine needle biopsy.

Nodular pulmonary amyloidosis was diagnosed by percutaneous transthoracic fine needle biopsy specimen in an 88-year-old woman. Congo red staining should be performed whenever band-like hyalinized material is obtained on aspiration of a solitary nodule. Dense calcifications can occur in pulmonary amyloidomas. In selected cases, fine needle biopsy appears to be preferable to transbronchial forceps biopsy since the risk of a possibly life-threatening pulmonary hemorrhage may be lower.
