Laboratory test findings were unremarkable. A blood test for human immunodeficiency virus was negative. Computed Tomography (CT) showed multiple well-delimited osteolytic lesions with no sclerotic halo or contrast enhancement affecting the sternum, elbows, ilium, sacroiliac joint, knees, and ankles, with no evidence of periosteal reaction (<a class="elsevierStyleCrossRef" href="#fig0001">Fig. 1</a>). There was no sign of pulmonary involvement. Metastatic disease was suspected. On Positron Emission Tomography (PET)/CT, Fluorodeoxyglucose (FDG) uptake was intense in the osteolytic lesions (maximum standard uptake = 14.3; <a class="elsevierStyleCrossRef" href="#fig0002">Fig. 2</a>) and some mediastinal lymph nodes. The diagnosis of Paracoccidioidomycosis (PCM) was confirmed through direct mycological examination of a lymph-node biopsy sample, which demonstrated spherical, thick-walled yeast cells of variable size, with peripheral buds protruding from a central cell, a pattern called the “pilot's wheel”, characteristic of <span class="elsevierStyleItalic">Paracoccidioides brasiliensis.
