We report the case of a 68-year-old woman with autoimmune hepatitis (AIH) who had leg ulcers induced by disseminated cryptococcosis. She had received prednisolone for her AIH at 20 mg/day for maintenance. On the initial visit, she complained of a painful ulcer that had round, shallow pockets with erythema and erythematous subcutaneous indurations on the right thigh. Several metacarpophalangeal joints and wrist joints were swollen, with tenderness and stiffness in the morning for over 3 h. Her serum rheumatoid factor was high. Since other autoimmune disorders such as rheumatoid arthritis can present with AIH, it was necessary to distinguish it from ulcers due to rheumatoid arthritis, although the characteristic features of these ulcers seemed to be different. A biopsy specimen from the erythematous skin showed globe-shaped organisms in the dermis and subcutaneous tissues; vasculitis and phlebostasis were not observed. The results from computed tomography scans and sputum culture led to the diagnosis of disseminated cryptococcosis. The administration of fluconazole, fosfluconazole, and voriconazole for about 2 months improved the cryptococcal pneumonia, but the size of the skin ulcer enlarged. The administration was changed to itraconazole, which reduced the size. Cryptococcal infections occur more commonly in immunocompromised hosts, including patients under immunosuppressive therapies such as corticosteroids. The possibility that the skin ulcers in immunocompromised hosts may be caused by cryptococcosis should be considered.

Cryptococcal infections are responsible for significant morbidity and mortality in immunocompromised patients. Reports of these infections in patients on small molecular kinase inhibitors have not been widely reported in clinical trials. We describe one case of cryptococcal meningoencephalitis and one case of cryptococcal pneumonia in two patients who were receiving ibrutinib for chronic lymphocytic leukemia. Despite different sites of cryptococcal infection, both patients had similar presentations of acute illness. Patient 1 was worked up for health care-associated pneumonia, as well as acute sinusitis prior to the diagnosis of cryptococcal meningoencephalitis. He also had a more complex past medical history than patient 2. Patient 2 developed atrial fibrillation from ibrutinib prior to admission for presumed health care-associated pneumonia. Cryptococcal antigen testing was done sooner in this patient due to patient receiving high-dose steroids for the treatment of underlying hemolytic anemia. We conclude that patients who develop acute illness while receiving ibrutinib should be considered for cryptococcal antigen testing.
