Kerion of the pubis is a deep dermatophyte infection with systemic symptoms, rarely affecting the genital area. We present three new cases of kerion of the pubis secondary to Microsporum canis infection.
Direct examination with potassium hydroxide solution showed hyaline septate hyphae and chains of arthroconidia around the hair shaft. Microsporum canis was isolated in culture in all of the cases, with yellow to orange colonies on Sabouraud agar. Identification by mass spectrometry was made using MALDI-TOF. Patients were treated with griseofulvin.
Clinicians should have a high index of clinical suspicion for deep fungal infection when patients present with suppurative infections or folliculitis-like lesions on the mons pubis area.
耻骨部脓癣是一种伴有全身症状的深部皮肤癣菌感染，很少累及生殖器区域。我们报告3例犬小孢子菌感染继发耻骨部脓癣的新病例。
氢氧化钾溶液直接镜检显示在毛干周围有透明分隔菌丝和关节孢子链。所有病例培养均分离出犬小孢子菌，在沙氏琼脂上形成黄色至橙色菌落。采用基质辅助激光解吸电离飞行时间质谱（MALDI-TOF）进行鉴定。患者接受灰黄霉素治疗。
当患者在耻骨区出现化脓性感染或毛囊炎样损害时，临床医生应高度怀疑深部真菌感染。
