A 25 year old hairdresser was referred acutely following the development of pruritic pink papules and subsequently bullae, 24 h after the application of a temporary black henna tattoo to the dorsum of both of her hands by a family friend. In addition, she had fallen asleep for several hours with her hand resting under her chin and had noted redness and swelling within the pattern of her tattoo in this location also. She reported previously developing a pruritic, erythematous eruption over her hands following colouring her clients' hair and had started to use latex free gloves at work for this activity.
