Population migration is increasing the number of systemic mycosis cases, a condition little or not present in Metropolitan France, thus often weakly documented for medical teams.

Paracoccidioidomycosis is a systemic mycosis geographically confined to Latin America. The causative agent is Paracoccidioides brasiliensis, a dimorphic fungus present at ground level. Discovering that the armadillo was a new host allowed documenting the ideal conditions for this fungus development. The mortality rate is currently 1.45 for one million people and the disease affects mainly farmers. The mode of infection is respiratory and all organs and mucous membranes can be affected by lymphatic dissemination. The chronic form with pulmonary, cutaneous and oral lesions is the most important.

The diagnosis can be carried out by direct examination of samples revealing the presence of budding yeasts, as well as culture at 25 and 37 degrees C. Antifungals like the sulfamethoxazole-trimethoprime combination, amphotericin B, but especially azole derivatives are use in the therapeutic management of patients.

Detection and gp 43 antigen assay is useful for the patient's follow-up.
