Imported histoplasmosis in Spain.
Histoplasma capsulatum is a dimorphic fungus endemic in the American continent but not in Europe, where cases are usually imported. Its favorite habitat is in warm humid soils. Guano from birds and bats enhance the sporulation of the mycelial phase.1 Man acquires H. capsulatum through inhalation of spores. Most people infected by this fungi remain asymptomatic, but around 10-50% can start an illness ranging from acute pulmonary histoplasmosis to chronic histoplasmosis. In both, there is close clinical resemblance to pulmonary tuberculosis. Immunodepressed patients undergo a more severe form of the disease, usually presenting in the acute disseminated form. We present seven immunocompetent patients with histoplasmosis acquired after traveling to several American countries.
