Dermatophyte infection may present in the form of concentric rings caused by Trichophyton concentricum, known as Tinea Imbricata. In immunosuppressed patients, there are reports of lesions in the form of concentric rings caused by dermatophytes other than Trichophyton concentricum too, mostly by Trichophyton tonsurans, known as Tinea indesiciva or Tinea pseudoimbricata. We report a case of tinea capitis in a HIV-positive adult woman on antiretroviral therapy, who presented with concentric rings of papules and pustules with slight scaling on the scalp along with diffuse thinning of hair. Both Potassium hydroxide mount and culture showed the presence of Dermatophytes. Tinea capitis is considered rare in adults, but new cases are being reported in immunocompromised as well as in immunocompetent patients. The pertinent features of this case are: HIV-positive adult female on antiretroviral therapy, presenting with tinea capitis in the form of concentric rings; culture from the lesion grew Microsporum audouinii; responding to oral Terbinafine.
皮肤癣菌感染可能表现为由同心性毛癣菌引起的同心环形式，称为叠瓦癣。在免疫抑制患者中，也有报道称除同心性毛癣菌外的其他皮肤癣菌引起的同心环形式的病变，主要是断发毛癣菌，称为非典型癣或假叠瓦癣。我们报告一例接受抗逆转录病毒治疗的HIV阳性成年女性头癣病例，该患者头皮出现丘疹和脓疱的同心环，并伴有轻微脱屑以及头发弥漫性稀疏。氢氧化钾涂片和培养均显示有皮肤癣菌存在。头癣在成年人中被认为较为罕见，但免疫功能低下以及免疫功能正常的患者中都有新病例报道。该病例的相关特征为：接受抗逆转录病毒治疗的HIV阳性成年女性，表现为同心环形式的头癣；病变部位培养出奥杜盎小孢子菌；对口服特比萘芬有反应。
