Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics. A second biopsy showed fungal hyphae, and he was treated with itraconazole 200mg bid for 4months beyond clinical resolution. A year later, he presented with intermittent swelling of the right forehead lesion and worsening of the scalp lesions. A forehead biopsy showed interface dermatitis and negative PAS stain for fungi. Scalp biopsy was highly suggestive of discoid lupus and he was started on plaquenil. Many months later, a third biopsy showed fungal infection, and the culture grew C. immitis. He was treated with itraconazole. Retrospectively, the patient gave a history of Valley fever 6 years back when he was in Arizona, USA.
球孢子菌病通常是通过吸入粗球孢子菌和波萨达斯球孢子菌的孢子而感染。该疾病范围从自限性急性肺炎(山谷热)到播散性疾病。我们报告一名44岁健康男性,他有持续数月的斑片状脱发,类似盘状狼疮。他右侧前额出现一个坚实的、无鳞屑的红色斑块。初次活检显示海绵状皮炎,他接受了全身性类固醇治疗。随后他出现前额和眶周蜂窝织炎,并接受了全身性抗生素治疗。第二次活检显示真菌菌丝,临床症状消退后,他接受了4个月的伊曲康唑治疗,剂量为每日两次,每次200毫克。一年后,他出现右侧前额病变间歇性肿胀,头皮病变加重。前额活检显示界面性皮炎,真菌过碘酸-雪夫染色阴性。头皮活检高度提示为盘状狼疮,他开始服用羟氯喹。数月后,第三次活检显示真菌感染,培养物培养出粗球孢子菌。他接受了伊曲康唑治疗。回顾性来看,患者6年前在美国亚利桑那州时曾患山谷热。
