Cryptococcus species is still a very common opportunistic infection in AIDS patients. However, it is increasingly responsible for disease in otherwise immunocompromised individuals, such as transplant recipients and the heterogeneous group of patients with underlying immunologic diseases, hematologic disorders and organ failure syndromes. Clinical presentation, prognosis, and outcomes are difficult to define given these varied host groups, and tailoring treatments to fit the necessities of each patient is likewise challenging. Our patient was on treatment with steroids and direct-acting antiviral agents (DAAs) for a chronic HCV-related hepatitis, worsened by cryoglobulinemia, membranoproliferative glomerulonephritis and a lowgrade B cells lymphoma. We report a case of systemic cryptococcal infection in an immunosenescent, HIV-negative patient.
