Circumscribed palmar hypokeratosis: case report and literature review


HF Cheng 鄭學輝, WY Lam 林永賢, KM Ho 何景文


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.
