A 54-year-old man developed a serious hand infection caused by Candida albicans, a yeast that normally lives harmlessly on human skin. The infection occurred because he had been taking large doses of corticosteroid injections for 15 years to help with breathing problems, which weakened his immune system. Doctors drained the infected area and treated him with antifungal medication, and he recovered completely, highlighting the importance of recognizing fungal infections in patients on long-term steroid therapy.
