Abstract
A 16-year-old Chinese girl presented with mildly itchy persistent rash over dorsa of her feet for four years. The rash began from her right big toe and increased in size progressively, causing difficulty in moving her ankle joints. She received various topical steroids and systemic antifungals from doctors but the response was poor. Her past health was good with normal developmental milestones. Her mother had similar rash over both legs since childhood. Physical examination revealed well-demarcated scaly erythematous plaques over her ankles, dorsal aspects of both feet, heels and soles (Figures 1 & 2).
