Abstract: We reported a case of Majocchi granuloma with inflammation around hair follicles in the scalp caused by Trichophyton rubrum, which was diagnosed by histopathology and fungal culture and strain identification. The patient was a 84-year-old male with papules and nodules on the bilateral temporal scalp for more than 1 year. Multiple red papules and nodules were observed on the bilateral temporal scalp, and some of them are fused into pieces. Histopathological examination showed an inflammatory infiltration area in the middle and lower dermis, with predominantly neutrophils and many tissue cells and multinucleated giant cells. Many hyphae and spores were observed in a hair shaft. Trichophyton rubrum was identified by fungal culture and strain identification. This patient was finally diagnosed as Majocchi granuloma on the scalp caused by Trichophyton rubrum. This patient was treated with itraconazole 0.2 g, twice a day, orally for 2 months. The patient's rash subsided. He is currently under follow-up.
