title: [A case of localized nodular pulmonary amyloidosis diagnosed by video-assisted thoracoscopic surgery].
abstract: Pulmonary amyloidosis is a rare pulmonary lesion. We report a 42-year-old male admitted for further evaluation of abnormal chest shadow. A chest CT demonstrated a nodular shadow in right S3. We tried transbronchial and percutaneous lung biopsy, but could not diagnose. We performed partial lung resection by video-assisted thoracoscopic surgery. Pathological diagnosis of the lesion was pulmonary amyloidosis. Immunohistochemical examination revealed this amyloid composed of AL kappa protein. No clinical evidence of amyloid deposits were found in other organs. We finally diagnosed this case as a localized nodular pulmonary amyloidosis.
