The lesions were pink to brown, irregularly shaped macules, 1–2 cm in diameter, disseminated prominently on her trunk (Fig. 1A) and extremities. The lesions were induced or exacerbated by mechanical friction. Erythema occurred after removing tape from the skin (Fig. 1B). Her palms and soles, hair and nails were spared. She was born without obvious abnormalities including bodyweight, skin disorders or other diseases at term after an uneventful preg- nancy. No history of atopy was reported, and her family history was unremarkable. A punch biopsy specimen was obtained from her dorsal skin. What is your diagnosis? See next page for answer. Fig. 1.
