[Recurrence of AL type primary localized pulmonary amyloidosis]

A 52-year-old female, who was diagnosed primary pulmonary amyloidosis by left open lung biopsy 11 years ago, has been pointed out chest abnormal shadow in the opposite lung for 9 years. Two masses situated in the right S3a and S4 have been growing gradually with suspicion of malignancy. The right open lung biopsy revealed amyloidosis by frozen section and wedge resections were performed. Microscopic findings were compatible with AL type amyloid protein. We reported a rare case of recurrence of localized primary pulmonary amyloidosis.
