Abstract:
:Paracoccidioidomycosis is a systemic mycosis with a geographic distribution that is limited to Central and South America; Brazil has the highest number of cases. Severe disseminated disease caused by paracoccidioidomycosis was observed in acquired immunodeficiency syndrome patients who live or have resided in endemic paracoccidioidomycosis areas. Here we describe a male patient admitted to a large public hospital with diffuse nodular infiltrates observed in chest radiographs and with erosion at the second rib near the sternum. Blood tests showed anti-human immunodeficiency virus antibodies, a human immunodeficiency virus viral load of 59,700 (4.8 log), and CD4 144/mm(3), with negative serology result for fungal infections. Aspirate of the rib lesion showed cells with a typical morphology of Paracoccidioides brasiliensis, aside from benign inflammatory cells. The histology of the rib biopsy showed typical granulomas and immunostained fungal cells. Although there was no growth in the Sabouraud cultures, Paracoccidioides brasiliensis gp43 and rDNA genes were detected in the aspirate by polymerase chain reaction. Therapy with amphotericin resulted in complete recovery. This type of bone lesion is rare and has been described primarily in the juvenile form of paracoccidioidomycosis; it must be included in the differential diagnosis of bone lesions in adult acquired immunodeficiency syndrome patients of endemic areas.
