一名 14 歲男孩進來，頭皮上有厚厚的黃棕色鱗片，主要分佈在前額和頂部。患處呈紅色，有鱗屑，毛髮脫落，無疤痕。真菌檢測呈陰性。
A 14-year-old male patient presented with focal masses of thick, adherent, plate like, yellow-brown scales, attached to the hair shafts, predominantly affecting the fronto-parietal area and vertex of the scalp. The underlying scalp had thick, erythematous plaques with fine, non greasy, silvery-white scaling with noncicatricial alopecia. Potassium hydroxide examination of scales and hair and culture for fungus was negative.

Pityriasis amiantacea 可能來自任何主要影響頭皮的皮膚病，例如 seborrheic dermatitis 。但我們並不完全確定它是如何開始的。我們的目標是研究 pityriasis amiantacea 患者的模式，以了解治療如何更好地發揮作用。我們檢查了 63 名患有 seborrheic dermatitis 的孩子，發現了 7 例 pityriasis amiantacea 病例，其中大多數是女孩。我們平均追蹤他們約 20. 4 個月，發現他們的年齡約為 5. 9 歲。其中，女孩5人，平均年齡9歲。所有患者均成功接受局部酮康唑治療。
The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole.

石棉状糠疹 (pityriasis amiantacea) 影響頭皮，表現為閃亮的厚鱗片。鱗片包圍並束縛一簇毛髮。這種情況可以是局部的，也可以覆蓋整個頭皮。由於反覆去除鱗屑上附著的毛髮，可能會出現暫時性脫髮和疤痕性脫髮。這是一種罕見的疾病。
