[Primary pulmonary nodular amyloidosis].

Localized nodular pulmonary amyloidosis is a very rare condition. We report the case of a man with an upper left lobe mass measuring 8 cm and a nodule measuring 3 cm at the same site. Both were detected by chance in radiologic images. Neoplasia was suspected and diagnosis was made by thoracotomy and lung biopsy. After two years of follow-up, the patient remains asymptomatic and the radiologic images are stable, with no clinical or analytical evidence of systemic amyloidosis or dysproteinemia.
