Abstract

Pulmonary malakoplakia is a rare lung lesion more frequently found in immunocompromised patients than in immunocompetent individuals. In this study, we report the challenging case of a young immunocompetent patient with an irregular pulmonary nodule with peripheral cysts who, after undergoing surgery, was diagnosed with malakoplakia. Due to the rarity of the disease and the similarity of this condition to malignant neoplasms, cytopathological or histopathological examinations are necessary for the correct diagnosis. A description of pulmonary malakoplakia with peripheral cysts has not been previously published in the literature.
