Majocchi's granuloma is an uncommon fungal infection of the dermis and subcutaneous tissue. The most frequently identified cause of Majocchi’s granuloma is anthropophilic Trichophyton rubrum, and it is most commonly located on the anterior aspect of the lower limbs in women. Here, we report a case of Majocchi’s granuloma on the forearm, a site that is rarely involved, in a 62-year-old woman who had been bitten by a dog. Histological examination revealed a dense dermal infiltrate composed of lymphoplasmacytic cells and neutrophils, with hyphae in the dermis. The presence of the fungus, Trichophyton tonsurans, was confirmed by mycological examination and molecular methods. Therefore, histological and mycological examination confirmed the diagnosis of Majocchi’s granuloma. The patient was treated with local moxibustion and itraconazole, 200 mg/day, for 60 days, which facilitated a complete resolution of the lesions.

免疫功能正常的患者中，由扁桃体癣菌引起的前臂上的马约奇肉芽肿。

Majocchi肉芽肿是真皮和皮下组织的罕见真菌感染。Majocchi肉芽肿最常见的原因是嗜人毛癣菌，它最常见于女性下肢的前部。在这里，我们报告了一个前臂上马乔奇肉芽肿的病例，该部位很少涉及到一名被狗咬伤的62岁妇女中。组织学检查显示，由淋巴浆细胞和中性粒细胞组成的致密真皮浸润，真皮中有菌丝。通过真菌学检查和分子方法证实了真菌毛囊癣菌的存在。因此，组织学和真菌学检查证实了马约奇肉芽肿的诊断。该患者接受局部艾灸和伊曲康唑治疗，
