足菌肿是由多种真菌侵入皮肤和皮下组织引起的慢性化脓性、肉芽肿性疾病,临床上以形成皮下肿块、多发性窦道、排出脓液中带有真菌颗粒等为特征。足菌肿分成两类:①放线菌性足菌肿,由放线菌属、奴卡氏菌属、链丝菌属引起。②真菌性足菌肿又称足分枝菌病,由足分枝菌属、单孢子菌属等较高级真菌引起。两类足菌肿临床症状虽然相似,但治疗及预后不同,因此病原菌鉴定有重要的临床意义。 Pedunculobrinus is a chronic suppurative and granulomatous disease caused by a variety of fungi invade the skin and subcutaneous tissue. Clinically, it is characterized by the formation of subcutaneous tumors, multiple sinuses and discharge of fungal particles in the pus. Pediatric swollen can be divided into two categories: ① actinomycosis plica, actinomycetes, Nocardia genus, caused by Streptomyces. ② fungal foot fungus, also known as foot mycosis, mycobacterium, mycoplasma and other higher fungi caused. Although the clinical symptoms of two types of footpipe are similar, but the treatment and prognosis are different, so the pathogen identification has important clinical significance.
