A 16-year-old male patient was admitted to the study hospital with a 6-month history of two itchy, round, xerotic lesions affecting the skin on his wrists. A definite diagnosis was not made in the local hospital, and antibiotics were administered without improvement. Using mycological culture and intergenic transcriptional space sequencing, the patient was diagnosed with a Knufia epidermidis (K. epidermidis) infection and successfully treated with itraconazole at a dosage of 200 mg/day and acitretin at a dosage of 20 mg/day for 2 weeks. It is worth noting that K. epidermidis is a pathogen that can cause cutaneous infections. Doctors should be aware of this disease to avoid misdiagnosis.
