Abstract

Inflammatory pseudotumors of the bronchus have been reported infrequently. Histologic diagnosis remains difficult because of their Polymorphic histologic characteristics and confusing terminology, which are also the problems in the diagnosis of intrapulmonary pseudotumors. We report a case of inflammatory pseudotumor in the left main bronchus which occurred in a 37-year-old man. Histologically, the main portion of the tumor was composed of pale eosinophilic spindle shaped cells covered by respiratory epithelium with squamous metaplasia. Mononuclear inflammatory cells, including plasma cells but acute inflammatory cells were also present in the superficial portion.
