Prurigo pigmentosa following laparoscopic gastric sleeve.

Prurigo pigmentosa is an uncommon inflammatory skin disease predominately affecting young women. Clinically the disease presents with erythematous and urticarial papules arranged in a reticular pattern. Lesions heal with reticulated hyperpigmentation. Strict ketogenic diet is one of many factors that might trigger the disease. In this article, we present a case of prurigo pigmentosa following a complicated laparoscopic gastric sleeve with the resolution of the rash after improvement of the patient's diet.
