케톤형성 식이요법으로 인해 발생한 색소침착가려움발진 2예

초록

Prurigo pigmentosa (PP) is a rare inflammatory skin disease that commonly affects Asian women. It is characterizedby symmetric pruritic eruptions in a reticular pattern, primarily on the back, chest, or neck. The etiology of PP isunclear; however, it is estimated that neutrophil-mediated inflammation of the skin is induced by various exogenousstressors, such as friction from clothing and sweating. In addition to exogenous factors, some cases are thought tobe related to ketosis, diabetes mellitus, fasting, or dieting to lose weight. With the increasing popularity of ketogenicdiets, cases of PP are being more commonly reported. To raise awareness of this disease, we present two cases ofPP that occurred after following a ketogenic diet.
