茄病镰刀霉引起皮肤透明丝孢霉病1例

A Case of Cutaneous Hyalohyphomycosis Caused by Fusarium Solani

报告 1例茄病镰刀霉引起的皮肤透明丝孢霉病。从患者皮损取材作镜检、培养及组织病理学检查。结果 ,直接镜检及组织病理切片均发现真菌菌丝 ,4次培养均为同一菌株生长。镜下可见大分生孢子位于短的分枝的分生孢子梗上 ,基部细胞短、钝圆并伴有不明显的足细胞 ,小分生孢子丰富 ,位于长的分生孢子梗上呈假头状着生 ,厚壁孢子常见 ,单细胞或双细胞 ,顶生或间生 ,壁光滑或粗糙。根据以上特征 ,该菌鉴定为茄病镰刀霉。

To report a case of cutaneous hyalohyphomycosis caused by Fusarium solani. Specimens were taken from skin of the patient, then, microscopy, fungal culture and histopathological examination done to identify the pathogen. Fungal hyphae were found on direct microscopy and histopathological examination. Same strain grew on mycological culture medium for 4 times. Macroconidia produced on shorter, branched conidiophores, with short, blunt apical and indistinct foot-cell. Microconidia usually abundant, producted on long phialides, accumulating in slimy heads. Chlamydospores were frequent,single or in pairs,terminal or intercalary, smooth-or rough-walled. Based on the above characteristics, this strain was identified as Fusarium solani.
