黄斑癣是一种慢性头皮炎症性皮肤真菌感染，影响90%以上的嗜人性舍氏毛癣患者。此外，还发现了堇菜T.、疣状T.、嗜兽T. mentagrophytes（称为“quinckeanum变种”）、犬小孢子菌和嗜地M. gypseum。蚕豆病通常是一种儿童疾病，但成人病例并不罕见。有趣的是，尽管家族内感染已被报道并在文献中被广泛讨论，但蚕豆病的传染性比其他皮肤病要低。schoenleinit感染的临床表现是可变的：这种真菌可以从出现为灰色斑块的头癣病变中分离出来，但也会出现无症状的头皮定植。虽然在过去，schoenleinii是主要的真菌，从皮癣性头皮病变中恢复，但在世界范围内，除中国，尼日利亚和伊朗外，发病率有所下降。无毛皮肤和指甲的病例比头皮的病例少。本文综述了大肠杆菌的临床特点、病原、全球流行病学、实验室诊断和医学真菌学的简短历史。
Tinea capitis favosa, a chronic inflammatory dermatophyte infection of the scalp, affects over 90% of patients with anthropophilic Trichophyton schoenleinii. T. violaceum, T. verrucosum, zoophilic T. mentagrophytes (referred to as 'var. quinckeanum'), Microsporum canis, and geophilic M. gypseum have also been recovered from favic lesions. Favus is typically a childhood disease, yet adult cases are not uncommon. Interestingly, favus is less contagious than other dermatophytoses, although intrafamilial infections are reported and have been widely discussed in the literature. Clinical presentation of T. schoenleinii infections is variable: this fungus can be isolated from tinea capitis lesions that appear as gray patches, but symptom-free colonization of the scalp also occurs. Although in the past T. schoenleinii was the dominant fungus recovered from dermatophytic scalp lesions, worldwide the incidence has decreased except in China, Nigeria, and Iran. Favus of the glabrous skin and nails are reported less frequently than favus of the scalp. This review discusses the clinical features of favus, as well as the etiological agents, global epidemiology, laboratory diagnosis, and a short history of medical mycology.
