A rare pulmonary zygomycosis manifested as chronic mediastinitis and bronchial perforation

摘要

Zygomycosis is an emerging infection caused by fungi of class Zygomycetes, order Mucorales. It occurs mostly in diabetic and immunocompromised patients, but occasionally occurs in immunocompetent individuals [1]. After rhinocerebral zygomycosis, pulmonary zygomycosis, which carries a high mortality rate, is the second most common presentation [1]. Common manifestations of pulmonary zygomycosis mainly include different types of pulmonary infiltrates [2], and other rare manifestations such as endobronchial mass lesions or mediastinitis. However, in the literature, bronchial perforation caused by zygomycetes has not been previously documented. This report presents the case of a diabetic patient infected with Rhizopus sp., which resulted in chronic mediastinitis and bronchial perforation.
