Prurigo nodularis (PN) is a rare, chronic dermatologic disease that
causes intense pruritus, leading to significant physiological and psy-
chological discomfort and a diminished quality of life. The estimated
prevalence of PN is 72 per 100,000 Americans, and most often presents
later in adulthood, between the ages of 51-65, with African-American
patients 3.4 times more likely to have PN than white patients [1, 2].
The typical clinical presentations of this dermatological disorder are
intensely pruritic papules, plaques, and nodules that are multiple in
number, firm, and flesh to pink colored.
