Papular urticaria in Adult
The lesions are firm, pink, raised, 2- to 8-mm papules, often with a visible central punctum. They may become excoriated or secondarily infected. They can last weeks to months and often recur at the same time each year. Often, only one person in the household is affected and caregivers are disbelieving of proposed cause. After resolution of the papule, pigmented (postinflammatory) macules may persist.
