A localized pleuropulmonary lesion induced by long-term therapy with amiodarone.
Pulmonary toxicity is an important adverse effect of amiodarone therapy that usually manifests as an acute or chronic diffuse lung disease; in rare cases localized lesions have also been described. We observed a solitary mass localized in the left lung base and involving the adjacent pleura in a 69-year-old man who had been treated for 1 year with amiodarone (cumulative dose 52 g). Cytological and histological examination showed that the lesion consisted of fibrotic tissue and a massive macrophagic infiltration. Following suspension of amiodarone and surgical excision, there was a complete recovery and the mass did not relapse. We confirm that respiratory complaints can occur in patients treated by long-term amiodarone therapy and that lung involvement can manifest with a solitary localized (fibrotic) lesion.
