An 83-year-old man presented with an approximately 1-year history of an extensive inflammatory purulent crusted lesion in the bald area of the scalp diagnosed as tinea caused by Trichophyton rubrum. The scalp biopsy specimen showed suppurative folliculitis with perifollicular abscesses in upper dermis, and periodic acid-Schiff-positive fungal elements within the hair follicles and in the hyperkeratotic horny layer. The infection probably spread from diseased fingernails. A cure of the scalp lesion was achieved 2 months after starting daily oral treatment with 250 mg terbinafine. To our knowledge, the case presented is the first in which a suppurative abscess-forming T. rubrum infection of the bald area of the scalp in an immunocompetent man has been described.
一位 83 岁男性，头皮光秃部位有一处广泛的炎症性脓性结痂病变，病史约 1 年，被诊断为红色毛癣菌引起的癣病。头皮活检标本显示化脓性滤泡炎，真皮上部有毛囊周围脓肿，在毛囊内和过度角化的角质层中有过碘酸希夫阳性真菌。感染可能从患病的指甲传播而来。开始每天口服 250 毫克特比萘芬治疗 2 个月后，头皮病变痊愈。据我们所知，本病例是首例免疫功能正常的男性头皮光秃部位形成脓性脓肿的红色毛癣菌感染的病例。
