We report two cases of tinea corporis purpurica of the legs, presumably caused by self-inoculation of the mycete from the toenails, in two elderly women (80 and 78 years). Trichophyton violaceum was isolated from the skin and nails. Histological examination of a biopsy specimen from the leg lesions confirmed the diagnosis. The source of infection was an Ethiopian carer who had tinea capitis in the first case, and was undiagnosed in the second patient. Cases of purpuric variants of tinea corporis are rare and this is the first report of probable self-inoculation of T. violaceum from onychomycosis.
我们报告了两例腿部紫色体癣病例,推测是由真菌从趾甲自体接种引起的,发生于两名老年女性(80 岁和 78 岁)。紫色毛癣菌从皮肤和指甲中分离出来。腿部病变活检标本的组织学检查证实了诊断。感染源是一名埃塞俄比亚护理员,她在第一例病例中患有头癣,而在第二例患者中未被诊断。紫色体癣的瘀斑变体病例较为罕见,这是首次报道可能由甲真菌病自体接种紫色毛癣菌引起的病例。
