文献摘要

Rare molds are increasingly emerging as a cause of deep and invasive fungal infections. We report here a rare case of cutaneous phaeohyphomycosis of the lower limbs due to Alternaria alternata associated with extra-ungual localization of Scopulariopsis brevicaulis. Diagnosis was made based on repeated, direct, microscopic mycological and histological examinations. The study revealed hyphae and fungal cells in a granulomatous dermal infiltrate. Identification of the molds was based on macroscopic appearance on culture of samples from the lesions on Sabouraud’s dextrose agar and microscopic appearance on Lactophenol cotton blue following slide culture.

稀有霉菌越来越多的成为引起深度和侵袭性真菌感染的原因。我们报道了一例下肢皮肤暗色丝孢霉病的稀有病例, 由与短帚霉的超爪样定位相关的链格孢菌引起。诊断是在重复、直接、微观真菌学和组织学检查的基础上完成的。本研究揭示肉芽肿性皮肤渗透物中的菌丝和真菌细胞。通过在Sabouraud’s葡萄糖琼脂上培养皮损处样品的宏观表征,以及在玻片培养下乳酚棉蓝的微观表征对霉菌进行鉴定。
