Curvularia lung infection mimics malignancy

Curvularia rarely causes human infections despite its ubiquity in the environment. It is most associated with allergic diseases such as chronic sinusitis and allergic bronchopulmonary mycosis; however, causing a lung mass is rarely reported in the literature. We describe an interesting case of a 57-year-old man with a history of asthma and localized prostate cancer diagnosed with a Curvularia-caused lung mass that responded quickly to itraconazole.
