Post bariatric surgery prurigo pigmentosa in an adolescent.

Prurigo pigmentosa is an inflammatory skin condition that is characterized by the presence of pruritic reticulated hyperpigmented papules or vesicles of the upper trunk. Previously, this condition was rarely encountered until the rise in popularity of weight reduction methods. Even with the increased prevalence, most affected patients are still adults. We present the case of an adolescent who was successfully treated with doxycycline and encouraged to resume eating.
