Abstract：
Mycetoma is a chronic discharging infection involving the skin, subcutaneous tissue, fascia, and bone, which is endemic in tropical and subtropical countries. We report a rare case of mycetoma localized on the foot of a patient living in a country with a temperate climate. A 32-year-old male patient presented with painless swelling in the right foot. He had undergone surgery 3 years ago with the same complaints. Magnetic resonance imaging revealed a 90 × 65 × 37 mm cystic soft tissue lesion in the posterior of the right ankle. Histological analysis identified the fungus. Extensive resection was performed. Mycetoma is characterized by chronic granulomatous inflammatory response, often associated with sinus tract formations due to fungal (eumycetoma) or bacterial (actinomycetoma) organisms. Here we provide a literature review and highlight the importance of increasing awareness toward mycetoma, particularly in non-endemic regions.
摘要：
Mycetoma是一种累及皮肤的慢性分泌物感染，皮下组织,筋膜,还有骨头,这是热带和亚热带国家特有的。我们报告了一例罕见的细菌瘤病例，该病例位于温带气候国家的患者的脚上。一名32岁的男性患者表现为右脚无痛肿胀。三年前，他接受了同样的手术。磁共振成像显示右脚踝后部有90×65×37mm的囊性软组织病变。组织学分析鉴定了真菌。进行了广泛的切除。Mycetoma的特征是慢性肉芽肿性炎症反应，通常与由于真菌（细菌瘤）或细菌（放线菌瘤）生物引起的窦道形成有关。在这里，我们提供了文献综述，并强调了提高对霉菌瘤认识的重要性，特别是在非流行地区。
