Overinfection by Paracoccidioides brasiliensis in Gouty Crystal Arthritis.

Paracoccidioidomycosis is an endemic South American systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis (P. brasiliensis). The main clinical form of disease is pulmonary, but all organs may be involved. We report a case of overinfection by P. brasiliensis in chronic gouty arthritis affecting the proximal phalanx of the right hallux. The patient required proximal amputation and long-term antifungal therapy.
