Nodular pulmonary amyloidosis: diagnosis by fine-needle aspiration cytology and a review of the literature

Diagn Cytopathol. 1993 Oct;9(5):562-4. doi: 10.1002/dc.2840090519.

Abstract

Solitary nodular pulmonary amyloid tumor is an uncommon benign lesion which is seldom diagnosed prior to surgical extirpation. We present a case of unsuspected nodular pulmonary amyloid tumor diagnosed by fine needle aspiration cytology. A 52-yr-old-black woman, presented with a 3-cm right middle lobe mass. Percutaneous fine-needle aspiration cytology (FNA) of the mass revealed waxy amorphous material that demonstrated apple green birefringence on Congo Red Stain. Thoracotomy for diagnosis may be avoided by using FNA to diagnose these unusual lesions.
