%X <B>BACKGROUND: </B>Paracoccidioidomycosis is a neglected tropical disease caused by fungi of the genus Paracoccidioides. A wide range of symptoms is related to the disease; however, lungs and skin are the sites predominantly affected. The disease is mostly seen in people living in rural areas in Latin America.<BR><B>METHODS: </B>We present a pediatric case of severe disseminated paracoccidioidomycosis that slowly responded to the antifungal treatment. Within three months, symptoms evolved into hepatosplenomegaly, necrotic cervical and abdominal lymph nodes, and splenic abscess. Clinical response to amphotericin B deoxycholate and itraconazole was slow, resulting in pleural and peritoneal cavity effusions, heart failure and shock. Amphotericin B deoxycholate was replaced by the liposomal formulation, with no response. Subsequently, prednisone was added to the treatment, which led to improvement in the clinical response. Serological Paracoccidioides antibody titers were atypical, with very low titers in the critical phase and significant increase during the convalescence phase. The infection was finally cleared up with amphotericin B deoxycholate, liposomal amphotericin B and the use of corticosteroids. Paracoccidioidomycosis serology was non-reactive two years post-discharge.<BR><B>CONCLUSIONS: </B>Due to the intense inflammatory response triggered by Paracoccidioides cells, giving low-dose prednisone for a short period of time modulated the inflammatory response and supported antifungal treatment.
