Lung mycobacterium avium developed after removing an acupuncture needle from the lung

Abstract

Acupuncture needles can cause non-tuberculosis mycobacteria (NTM) infection on the skin, but there are no reports that acupuncture needles inserted into the lung have caused lung NTM infection. A 63-year-old woman, who underwent removal of a broken acupuncture needle inserted into the lung nine years ago, was admitted with nodules in the right lung. The shadow was positioned where the needle had existed. Partial lung resection of the right lower lobe was performed, and the resected area showed caseous necrosis histopathologically. Furthermore, Mycobacterium avium was cultured from the specimen. When abnormal lung shadows are located where a resected foreign body appeared, NTM infection should be considered.
