First Report of Nocardia asiatica Presenting as an Anterior Mediastinal Mass in a Patient with Myasthenia Gravis: A Case Report and Review of the Literature

Abstract

The spectrum of infections with Nocardia spp . is heterogeneous. It has classically been associated with lung, brain, or skin involvement. We describe an unusual presentation of Nocardia asiatica (N. asiatica) in an Iraqi patient with myasthenia gravis suffering from a disseminated infection and presenting with an anterior mediastinal cystic mass. N. asiatica has only been three times described outside Japan and Thailand, and the rarity of this entity deserves this communication.
