BD often develops in long-standing, uncontrolled diabetes, although there are reports of BD as the presenting sign of diabetes. Disabling BD has also been reported in older adult patients with optimal glycemic control. Bullae often resolve on their own without scarring, but recurrence is common, and new bullae can continue to form over a period of years. The average age of onset is 55 years, and there is a 2:1 male-to-female ratio.
