Coccidioidomycosis: an unexpected diagnosis in a patient with persistent cough.
Coccidioidomycosis is an endemic fungal infection of the new world caused by Coccidioides immitis. Because of its low incidence in the European continent, the disease is not well known in Belgium. A 34-year-old male was referred by his general physician with a chronic cough and a nodular infiltrate on chest X-ray. Because a malignant tumour was suspected, a diagnostic work-up was performed and, finally, a broad excision of the pulmonary lesion was carried out. The unsuspected diagnosis of chronic coccidioidomycosis was eventually made based on identification of the filamentous fungus in mycological culture of the lung tissue, and the presence of the typical spherules with endospores upon histopathologic examination. The patient later admitted to have been travelling to Arizona frequently in the past year for professional reasons. Coccidioides spp. should always be considered as a possible aetiologic agent of pulmonary infection in former residents and recent travellers to regions where the fungus is endemic.
