Abstract:
The patient was a 64-year-old asymptomatic man. His chest X-ray film, at age 61, showed a solitary nodule in the right middle lobe. Thoracoscopic surgery was performed. The nodule was pathologically diagnosed as a solitary nodular amyloidosis. After 3 years, his chest CT showed a solitary nodule in the left upper lung. Thoracoscopic surgery for the pulmonary nodule was performed again, and it was also pathologically diagnosed as a solitary nodular amyloidosis with AA type amyloid protein. Solitary nodular pulmonary amyloidosis is usually AL type, and few cases of solitary AA type amyloidosis have been reported. We reported a rare case of recurrence of solitary pulmonary amyloidosis.
