Aspergillosis is a multifaceted disease whose clinical manifestations (allergic, saprophytic and invasive forms) are determined by the host immune response. Allergic bronchopulmonary aspergillosis is characterized by corticosteroid-dependent asthma, fever, hemoptysis and destruction of the airways, which can evolve to fibrosis with honeycombing. The treatment consists of the combined use of a corticosteroid and itraconazole. Invasive pulmonary aspergillosis, which has a worse prognosis, is diagnosed based on histopathological documentation and positive culture of a sterile specimen. The treatment response obtained with voriconazole is better, in terms of survival and safety, than that obtained with amphotericin B. In patients with chronic pulmonary disease who are mildly immunocompromised, chronic necrotizing pulmonary aspergillosis causes progressive destruction of the lung. Such patients are treated with oral itraconazole. Chronic cavitary pulmonary aspergillosis causes multiple cavities, with or without aspergilloma, accompanied by pulmonary and systemic symptoms. In patients with chronic pulmonary disease, the aspergilloma is characterized by chronic productive cough and hemoptysis, together with a cavity containing a rounded, sometimes mobile, mass separated from the cavity wall by airspace. Surgical resection is the definitive treatment for both types of aspergillosis. Triazole fungicides provide long-term treatment benefits with minimal risk.
