Chronic mucocutaneous candidiasis, pancytopenia, and systemic mycosis in a patient with STAT1 gene mutation ineffectively treated with ruxolitinib

We present a case of a white adult female patient who suffered from chronic mucocutaneous candidiasis (CMC) since infancy. Her parents were not consanguineous, and neither of them nor any other family member, including an older sister, suffered from similar symptoms. The patient often received prolonged courses of antifungal antibiot-ics, but the regimens were always insufficiently effective. The differential diagnosis included atopic dermatitis or acrodermatitis enteropathica, a rare, usually genetic disor-der of zinc metabolism characterized by pustular dermatitis, diarrhea, and nail dystrophy.
