Abstract

Circumscribed palmo-plantar hypokeratosis is a rare entity. The morphology consists of a long-standing, solitary well-circumscribed macule with a sharp and mildly scaly border. It is usually found on the palms or soles. We report a case of 73-year-old Chinese woman who presented with such a lesion, with emphasis on the clinical and histopathological features. This is followed by a brief literature review.

局限性掌跖角化減少症是一種罕見病。形態上表現為長期單一的皮膚斑,邊界清淅伴有細鱗屑,常見於手掌或腳掌。我們報告了一例73歲的華裔婦女出現這種病變,重點探討其臨床和組織病理學特徵,並接續簡短的文獻綜述。
