Refractory coccidioidomycosis with progressive skeletal lesions despite prolonged use of antifungal therapy (amphotericin B and azoles). Surgical debridement with implantation of amphotericin B-impregnated beads. Adjunctive IFN-γ injection for M. kansasii infection with good response. Here, IFNG is linked to coccidioidomycosis.
