Primary cutaneous aspergillosis (PCA) occurs through direct skin inoculation via trauma, burns, or surgical wounds, with Aspergillus fumigatus, Aspergillus flavus, and Aspergillus niger as common causative species, and is rare in immunocompetent individuals. We report a case of PCA in a 56-year-old immunocompetent patient with facial and right ankle ulcers, persisting for two years. The patient had no history of diabetes, corticosteroid use, or immunodeficiency. Fungal culture and metagenomic next-generation sequencing (mNGS) confirmed A. flavus infection. Voriconazole therapy, surgical debridement, and specialized wound care led to the gradual healing of the ulcers. This case highlights the importance of early diagnosis and intervention to prevent infection spread and progression to systemic aspergillosis or septic shock.Keywords: invasive aspergillosis, primary cutaneous aspergillosis, A. flavus, fungal infection
